139 Postfassade Facade Competition, Honourable Mention, Cologne 2017

With their Post Office 3, Cologne, Joachim and Margot Schürmann monumentally, finely and humanely inserted an infrastructural building into the city. The BDA prize-wining Post Office 3 is a very serious work of architecture. In the tradition of great architects, the Schürmanns produced a whole in which all its considerations—from urban positioning to material dimensioning—interlock perfectly. In the 35 years since its design, however, the digital revolution has radically changed the industrial needs of the post. Conversion of the city block-sized building to living quarters therefore makes sense, but cannot be approached as a typical industrial building conversion. To preserve the spirit of Post Office 3 as it is adapted for a second cycle of use, requires the humble work of apprehension and analysis. The internal logic of the building, its principles and rules, must serve as the basis for its metamorphosis. 

One can see in its size, proportion and volumetric articulation, a reference to the palazzo of the Italian Renaissance at work in the Schürmanns design. They structured the building both vertically (in the base zone, middle zone and roof) and horizontally (in an overarching axial symmetry with emphases center and corner) according to classical rules. They then filled the exterior load-bearing skeleton of the post office with window bands and masonry bands, combining their pre-modern principles of structure and proportion with modern, precise construction. Consistent detailing is a principle of all good architecture; a labor which here resulted in concrete structures, masonry, metalwork and glasswork of outstanding quality. This uniquely modern glasswork (for the walkways along the street, the interior courtyard ring, and staircase to the roof) taken in tandem with the open terraces and stairs of the corners, expresses the final principle of the design: the life of the building is made visible. Joachim and Margot Schürmann have translated the movements of the people into architectural form.

These features form the basis for the new façade concept: transparent solidity. The façade becomes a climatic and acoustic space for habitation, allowing for the preservation of the buildings exquisite detailing (designed to fulfill 30-year-old energy requirements). A loggia is closed off with glass blocks and single-glazed reversible windows, extending the compact living spaces of the interior and inviting residents to vary connection to the outdoor space. From a distance, the classical solidity of the building’s preserved volumes is reinforced by the shiny surfaces of its materials, while from close-up, the façade reveals its multi-layeredness and new residential content. The new division of the flats in the floor plan is perceptible in the subtle rhythm of the reversible windows while the newly added upper floors introduce a slight syncopation to the western façade. The clear, slightly turquoise glass blocks fit effortlessly into the building’s dimensions and together with glazed brick parapets they introduce light blue and light green into the pallet of beige, grey and white. The tiled floor of the loggia adds a warm pink to the mix, without overpowering the façade. This new colorful residential character is repeated in the inner courtyard, where generous tiled terraces adopt the brick parapet, stepping back with each floor and providing all units with direct access to the sky.

111 Raderthal Urban Design Competition, Cologne 2014

status: competition
program: housing
location: Raderthalgürtel, Cologne
team: Anne-Julchen Bernhardt, Jörg Leeser, Paula Frasch, Matthias Hoffmann, Christiane Schmidt
client: PARETO GmbH
date: September 2014

Even after a century of development, Cologne’s ring road or ‚Gürtel’ contains large reserves for the potential development and expansion of Cologne. To integrate this expansion into the overarching urbanism of the ‘Gürtel,’ a precise urban morphological analysis of all sections of the Cologne Belt was conducted. The resulting catalogue of urban building blocks forms the ground out of which the proposal--‘Der Raderthalgürtel’--grows. The section of the ring in question is one of the youngest on the Cologne Belt. The 1970s construction of the ‘Deutsche Welle’ and ‘Deutschlandfunk’ high-rise buildings produced diffusely urbanized and intensified the area, which was still partly agricultural and partly industrial.

At 220 meters in length, the ‘Große Siedlungshaus’ is the horizontal counterweight to these high-rises, while the compact physical presence of such a large structure compliments and furthers the urban diversity of the greater ring road. Row houses with roof terraces face south onto the Gürtel, reflecting the characteristic 19th century reform urbanism of neighboring Klettenberg and Sülz. To the North, the Siedlungshaus presents a façade with seven towers and seven gates leading to seven interior courtyards. These courtyards are shielded from street noise by the row houses, but because of their low stature, still receive generous amounts of sunlight. The adjacency of the large ring road with the small housing typologies generates an interplay of private and public space for all ages. Semi-private niches face to the North while a series of Jane Jacobs-esque stoops lead South onto to ring road sidewalk. The uniformly distributed through-ways gently describe interior yards in which ‘en passant’ supervision of children comes naturally.

Cooperative Small Town 2050

"Neither the village nor the big city makes any serious effort to fulfill the demand that has always existed for us: to develop everything individually and in such a way as to be as organic as possible, or leading of a self-sustaining life."
Heinrich Tessenow: Handwerk und Kleinstadt, Berlin, 1919, p. 15

"Since [the small town] can indeed, to a great extent, form a world for itself and seek to develop independence, the freedom of all other worldly circles is self-evident to it, and as the small town strives for its own personal existence, it recognizes immediately, from within itself, the conditions of personal freedom, and thereby, in the large-worldly or large-political sense, the ability to take interest and action again."
Heinrich Tessenow: Handwerk und Kleinstadt, Berlin, 1919, p. 62

Germany is characterized by contradictory developments; in the big cities there is a housing shortage, while rural regions are drying up. This is more evident in Thuringia than in other federal states; while the cities of Erfurt, Weimar and Jena are growing, the other municipalities are predicted to experience a dramatic population decline over the coming decades (see Bertelsmann Stiftung, 2015). In Apolda however, its structural, social and economic distinction from the big cities is not seen as a disadvantage, but as a basic requirement for sustainable development. The Cooperative Small Town 2050 envisions the balanced small town of the future, focusing on regulative practices in the areas of energy, food production, and labor. Apolda thus serves as a model for a federal state consisting primarily of villages, small and medium-sized towns.

This Cooperative Town is framed as a ‘work in progress.’ It does not follow a master plan, but develops according to a charter with cooperatively agreed goals, decided on by the Future Council. The council is interdisciplinary by nature, bringing together interested citizens and potential citizens of Apolda. They are responsible for developing regenerative systems of transport, food, energy, work and education; which projects are implemented in which order thus depends on the towns citizens. The diversity of the measures, their distribution in the area and their networking are therefore decisive.

The Future Councils meet regularly in the charter space on the RST site, where a multidisciplinary technical school focuses on the development of cradle-to-cradle. The school consists of workshops, experimental fields, exhibition and seminar rooms, library, studios, co-working, work yard, warehouse, start-up labs, the charter meeting room, café, beer garden, combined heat and power plant, market and housing. The school is a microcosm of the model town. Here, craftsmen, artists and scientists learn, live and work together on the questions of the future, testing and modeling autonomous systems. The school grounds are not a fenced enclave, but part of the city; a new service road crosses the campus, connecting all the school's public spaces and opening them up to the surrounding town. The pupils thus research and live in community with the townspeople, integrated into the society they serve.

137 Hallen Kalk Urban Design Workshop, 1st prize, Cologne 2017 – BeL & Studio Vulkan & Prof. Dr. Guido Spars

status: urban design workshop, 1st prize
program: multi-use: school, kindergarten, workshops, community areas, housing, offices, public open spaces

South of Kalk’s main street is a place where large empty spaces lie half asleep. ‘Die Hallen Kalk’ (The Kalk Halls) are a series of very large, monumental, industrial spaces which—with little exception—have long remained closed to the public.

This is about to change: the industrial halls will become communal halls; the site will be mixed in with the street. To create a diversity of urban spaces, a diversity of strategies is applied. These strategies emerge from the qualities of the existing structure itself, and therefore—while diverse—are united in maintaining the original character of the Halls. The existing usages thus generate a sophisticated structure for implementing the new usages.

The Kalk halls under 3,500 m2 each receive distinct uses: a market hall, school hall, festival hall, studio hall, dance hall, craftsmen's hall, adventure hall, play hall, BMX park and residential courtyard. The juxtaposition of these large units creates a mesh of uses which give the surrounding spaces an urban liveliness. The larger spaces—up to 10,000 m2—are more ambiguous. Here, the different uses lie over and within each other, staggered or simultaneous, fostering unexpected human interactions. Through removal of the skylight glazing, Hall 70 is transformed into a large plaza. Here the schoolyard, sports areas, kindergarten, planting area, greenhouse and refectory/restaurant mingle to form an impressive and multi-layered space. The unique blend of spatial definition and open sky, combined with its sheer size, makes Hall 70 into a significant Kalk landmark. Architectural sublimity and cultural openness constitute here a new cornerstone for a developing neighborhood.

A Bernese Quarter

The new urban quarter on Viererfeld is being created in synergetic relation to the surrounding scenery - the Aare slope, the historic Enge promenade and the Bremgarten forest. In interpretation of the cinematic method "splitscreen," one half of the space is cast as landscape, the other half as urban. These two large figures—the city block and the city park—take up the scale of the perimeter and reinforce its magnificence with grand gestures. The city block is a typologically pure form wherein individual houses subordinate themselves to the whole, resulting in a large communal interior framed by private flats. The city park reinterprets this principle with intensive edge use and a coherent, open center. Both large figures thus oscillate between a monumental grandeur and small-scale spaces.

The linearity of Bern’s old town is continued by the city block and elevated into a principle of spatial experience. The block’s two long fronts—one facing the promenade and the other the park—locate the required density at the edge, thus leaving the largest possible space in the interior undeveloped. The continuity of the exterior co-exists with interior heterogeneity through parceling; the plot is here understood not only as a fundamental economic principle but also as a formative one. Plots allow for the realization of different house sizes (small/medium/large/very large) and economic models (building group/cooperative housing/ pension funds), creating both consistency and adaptability. This system maintains a calm exterior, while allowing the interior to develop its own qualities. It becomes a sort of ‘outside’ in its own rite; its own biotope—socially and ecologically held together by its size and character. Public paths traverse the courtyard, each breaking the perimeter at two joints—where visibility and connectivity concentrate public services—and forming three yards within the interior.

These paths connect the linear elements of promenade and block to the equally long city park. Following Camillo Sitte’s theories of irregular urban space, generous street square and park spaces are experienced in sequence, lending the quarter a heterogeneous, green, urban character. Criteria of perception and use thus produce the new Viererfeldpark, which consists of an intensively used edge and open inner commons. The spatial framework of the park is built of fine paths and high hedges, displaying a wide array of public uses along the periphery, while giving glimpses into the expansive interior. The hedges form commons of round cells aligned in a diagonal enfilade. This arrangement frames strong individual spaces, while the park’s impressive size remains visible along the axis. The circular path system circumnavigates the subspaces creating long movements, and connects the commons to the forest to the East and the new quarter to the West. Three tall houses are placed amongst the gardens to the South, accentuating the flowing space of the commons and completing an ensemble of spaces punctuated by alpine views and large oak trees.

AIT-Award 2012

The van Dyck roasting plant is located at Körnerstraße 43 in Cologne-Ehrenfeld, a district characterized by its development during the industrial revolution. Its dense, orthogonal street network is lined by Rhenish three-window houses. Workers and petty bourgeois lived here, while in the block interiors, artisanal businesses and companies such as Audi, 4711, Helios, Herbrand and the chocolate factory Kwatta maintained production facilities. Since the Second World War, many immigrant workers moved to neighborhood, and recent development has been characterized by gentrification. While Ehrenfeld's industrial and artisanal importance is steadily declining, the gastronomic offer is steadily growing.

The design concept of the newly founded coffee roastery Van Dyck hearkens back to the industrial founding of the neighborhood without nostalgia. The technical production processes of a coffee roaster become the central design element; the experience of production becomes a gastronomic idea. With the roasting machine as a tabernacle in the visual axis of the room and the packing table serving as connecting element to the shop window, the guests participate intensively in the production of the coffee. The visit becomes a tasting; coffee and food are served at the packing table. The privilege of participating in the roasters' lunch break—behind the scenes of a legendary production plant—determines the perception of van Dyck.

An automotive enthusiast's greatest happiness is a visit to the "hallowed halls," the production facilities of his beloved make. Coffee lovers worldwide can now enjoy daily van Dyck coffee on Körnerstrasse.

162 Volta Nord Urban Study, Basel 2020 – BeL & Marco Merz Marion Clauss & Studio Céline Baumann

with Marco Merz, Marion Clauss, Leonard Schaffner, Céline Baumann, Merlin Bauer, Martina Kausch, Martin Josephy, Bárbara Maçães Costa
client: City of Basel
date: January 2020

The site lies in the transition zone between the Volta industrial area and the St. Johann residential district. A juxtaposition of different scales and building forms defines the site, whose identity emerges in the field of tension between impressive large buildings and small, individual urban building blocks. This juxtaposition is fruitful. Although the buildings and open spaces of the industrial plants follow exclusively logistical necessities, they form qualitative urban spaces which, when converted, result in multi-layered living environments. The urban structure of the design takes up the potential of this industrial context, interweaving the needs of a mixed living and working quarter with the expressive spaces of the industrial environment.

From three elementary typologies—the bar, courtyard building, and comb—a series of large conglomerates are born; creatures with a shifting open-closed character. One moment they appear as object-like solitaires, while the next they yield to the open spaces with a touching intimacy. These large entities are formed from groups of smaller individual typologies which vary in height between five and nine stories; optimized for the lighting of all interior and exterior spaces. A multitude of yards, courts and niches are formed by these large volumes, offering acoustic protection from the noise of the surroundings; each dwelling has at least one façade facing a protected area.

The hierarchy of these spaces—their zones of graduated privacy—can be grasped intuitively. Two vistas into the park in the northern part of the development signal accessibility without thresholds, while large yards—formed with the simple bar-type buildings and characterized by a high degree of collectivity—open to the street for commercial, artistic, educational, or communal uses. The courtyard building-type entrance courts provide a somewhat smaller communal space for residents, while the comb-type buildings, with their small pockets of semi-private space, stitch a small-scale residential character into the industrial-scale surroundings.

070 Big Plate Competition, Oslo, Norway 2009

status: competition
program: National Museum of Art, Architecture and Design at Vestbanen
location: Oslo, Norway
team: Anne-Julchen Bernhardt, Jörg Leeser, Kristina Eickmeier, Wolfgang Zeh
gross floor area: 36.000 m2
client: Statsbygg, Oslo
date: June 2009

Vestbanen is a void waiting to be charged. The modest size of the remaining landmarked station buildings is as absurdly disproportionate to the scale of the site as it is to the importance of the National Museum. To incorporate the large building masses into this delicate context, museum and office functions are assigned to two separate volumes. They share the same urban density but can be developed and realized individually. The museum is a horizontal slab, the office building a diverse vertical volume. Both typologies are derived from the immediate physical and historical context. Both pay tribute to the neighboring urban fabric and the landmarked station buildings.

Assimilating to the scale of the station buildings in height, the museum fosters the dignity of the landmarks without dwarfing them. Its magnitude as a National Museum is developed in the horizontal plane. Its vast footprint stems from the typologies of shipyards as well as train stations. It is modest in height but exuberant in depth. The new museum occupies the entire site, there is no figure ground relationship. There is no museum object but an all-embracing museum volume. The expansive footprint invigorates the existing public exteriors. There is an abundance of public space in the context. Triangular sculpture gardens charge the existing public spaces in front of the museum entrances.

The National Museum will stimulate intense urban density on the site. All public functions are at ground level. The public permeates into the museum through the open ground floor façade. The flatness of the new museum is horizontal monumentality. It is a deep space illuminated by controlled natural light. The friendly gallery maze is an open system to be appropriated by the public in time.

A universal enfilade system provides total flexibility and unlimited but controlled access. The low hierarchy of the spaces fosters incidental use and self-determination. The Lofted Archive is an indestructible container. It serves as a machine to preserve the cultural achievements of a society, which need to be stored and maintained. Serviced by functional cores and illuminated by light shafts, it's a heavy-duty workspace, forklift accessible.

client: KoWo Erfurt
date: February 2018

In the historic garden city, the residential courtyard is the spatial image used: buildings enclose a common space as a garden. In reference to this spatial image of social togetherness, a differentiated courtyard structure is created in Erfurt: individual buildings stand at the edge of the plot, leaving a common center free. The existing link between the Muskauer Platz neighborhood and the Gera floodplain is not cut off by the courtyard structure, but spatially charged. The openings between form transitions, from the residential area through the garden courtyard and into the Gera floodplain. The threshold spaces reference the gates of the historic garden city: four for foot and bike, one for foot, bike car, and fire brigade. In keeping with the courtyard type, all buildings are accessed from the garden, with additional entrances from the outside to avoid creating a backside.

The communal garden of approx. 3500 m² is used as a meeting point, offering not only a place to relax but also the opportunity to garden and harvest. The loose grove of fruit trees and the flowering meadows create a free, serene atmosphere. A garden house near the raised beds and the lawn creates a spatial anchor point, providing space for garden tools and movable furniture. Here, vegetables are cleaned, honey is extracted and juice is pressed together in autumn. The chosen plants attract insects and animals, thus reinforcing the character of the large, shared garden: consciously different from floodplain and actively cultivated by all 340 residents. 

To fulfill the systematization requirements of a garden city, the design consists of small series-buildings. While the outdoor space is a large form, the buildings are of medium size. In all five houses, the same flat types are grouped together; horizontally and—in the case of the larger ones, vertically—thus creating maximum repetition in the buildings. The garden houses are designed contextually; developed from the site, each with its own garden interpretation. The entire complex forms an encyclopedia of garden types and corresponding dwellings. The black pine house looks out into the forest and forms the main gateway to the courtyard. Bikes and cars are parked under the house, while the apartments above take on the quality of tree houses floating above the garden. To the North, staggered row houses feature extroverted gardens facing onto the floodplain, exemplifying private garden life. The conservatory house celebrates communal spaces with a framed roof terrace and a double facade. This envelope creates a buffer where exotic plants can grow year-round. The courtyard houses have the most radical reference to the garden, with living rooms at ground level, opening onto the introverted courtyard. Finally, the flower house crowns the yard. It is designed as a large cluster house of connectable individual flats, all with views into the park. The communal roof garden makes it a green beacon, while at the ground floor, a kiosk serves the park ice cream and lemonade.

The New Garden City Öjendorf is not a garden city, but a landscape city.

The space of fields framed with hedgerows, leading in gentle topography through oak avenues to the Öjendorf cemetery and Lake Öjendorf, contrasts in its original, beautiful, man-made, landscape character with the surrounding settlement space. The design attempts to create a symbiosis of landscape and development and to carefully refine the site.

The development is interpreted as a system of landscape halls that are habitats for people, animals and plants. A context for people is established via enfilades, while the thick floral walls form the habitat for animals. 

The field communities are developed as courtyard variants in relation to the landscape. The character of each ensemble is developed for the specific character of its field. A minimally invasive circulation system ties the twelve courtyard communities together, while each remains open to the landscape. Each flat, therefore, has views of the ecologically dense field edge. City and landscape city combine in view and movement.

The landscape city is the work of many. It relies on the commitment of its residents - in the planning, in the self-construction, in the maintenance and in the management. The design is not a final formal image, but a robust framework for living in the landscape.

St. Pauli is a neighborhood of Hamburg known for its red-light district and for its coexistence of extremes. ‘Der Kiez’ is a unique biotope for sub-cultures, one of the rare strongholds in the resistance against Disneyfication. The tenants here struggled for years to save the Esso Häuser from demolition, but after a forced eviction in December 2013, the protest's focus switched towards securing the return of tenants to a new building. Under the auspices of the so-called PlanBude an intense participation process with the citizens of St. Pauli took place. The PlanBude formulated the St. Pauli Code by conducting interviews and collecting over 2000 suggestions, wherein residents used drawings, clay models and letters to express their hopes and fantasies. This extraordinary bottom-up process formed the basis for an urban planning competition to develop the now vacant plot of slightly over 6.000 m² on the Reeperbahn.

The St. Pauli code in short:
1. Diversity instead of uniformity
2. Small-scaledness
3. Affordable instead expensive
4. Originality and tolerance
5. Appropriation and vitality
6. Experiment and subculture
7. Public space without consumerism

Is it possible to safeguard (or even catalyze) the specific character of St. Pauli in anything new?

The urban plan is based on a strategy of small parcels, ´Kleinteilig', in order to guarantee diversity. The overall plot will be subdivided in five properties, assorted according to their usage. This so-called Realteilung is deployed both as a social and an economic tool. Specific residential typologies are separated and organized into a series of individual buildings. Within each building, identical units are simply stacked; this lack of internal complexity keeps construction costs—and thus apartments—affordable. At the same time, the homogeneity within each building meets the heterogeneity of the entire complex on the streets.

This results in an urban complexity exemplified by the ground floor. It features 42 doors, providing access for residents and a cocktail of public functions. This sparking potential exchanges within the city; interactions are an instrument of tolerance. This street life is also diversified and organized through several tactics. Residential buildings are placed along the quieter Kastananienallee side of the development, while the hotel is placed on the much livelier Spielbudenplatz. To increase density and deal with zoning regulations, a new street is added to the site, greatly increasing the public perimeter of the block. Through an offsetting of the building mass at the street’s entrance, it creates a public space protected from the noise and reveling of the Reeperbahn. To this space, a collection of communal roofs, a shared courtyard, and a public balcony are added, completing an armada of places where the sub-cultures of St. Pauli, young creatives, hotel guests, residents of the apartments, families and the elderly can all mix and mingle.

date: April 2017

In the home of the Heimatmole building community, big life changes do not mean moving out, but small architectural changes. Having a child, caring for elderly parents, separations and group living arraignments can be accommodated by installing a new door or closing a doorway with a wooden stud wall. The house offers maximum adaptability through minimal intervention. This is made possible by an architecture structured around a multitude of neutral spaces. Not simple intermediate spaces, the rooms have precisely determined dimensions, allowing them to accommodate all facets of life; kitchen, workshop, bedroom, dining room, eat-in kitchen, children's room, utility room, music room, library, youth room and office now fit into every room. Through a central diffusion of bathrooms, water (and thus potential kitchens) is available throughout the floor-plan, allowing for a wide variety arrangements. The office, work room or guest flat can become autonomous without expensive conversion.

The building stands directly on the Warf plaza, enhancing the creative potential of the neighborhood with its mixture of living and working. The two-story base of the building features many doors, and a series of double height spaces. The most public of these is the communal ‘Heimatclub,’ while the others are the defining features of the four live/work maisonette apartments at ground level. These apartments are offered privacy by a thin layer of climbing plants. They are use-flexible, but achieve this not in their floorplan, but in their volume. The residents determine the character of their plaza though their individual decisions: is it studio, office, living room or kitchen at ground level? Each of these maisonettes is completed with a terrace on the courtyard side of the buildings.

Above the base, the relationship between the public side and the protected communal side is flipped. While on the Warftplatz the residents form a counterpart to the neighboring house, the courtyard side faces the Elbe river, visible to the whole city. On the upper floors therefore, the façade needs to offer privacy from the city while participating in its image. These contradictory requirements of protection and representation are handled with a green scaffold. This element is both technical and ecological in character, supporting a multitude of climbing and flowering plants, and crowned with an energy-harvesting wind turbine. This façade is no empty image, but full of life. Its balconies create a direct relationship between the courtyard and the building’s residents, offering views of and from the city, while flowering trellises attract birds and insects.

Agricultural engineers Ulrich and Kerstin Overmeyer have built a new biodynamic farm with a farm store, residential building, stable and barn on a ten-hectare plot in Emmelndorf. In front of the organic market garden on Emmelndorfer Straße, a large scattered fruit meadow and a wetland biotope have been created. "We want to make primary production tangible and make shopping a direct sensory experience," says Kerstin Overmeyer, explaining the concept. "We want to make sustainable management in harmony with nature tangible. Anyone who comes to us should immediately be immersed in our agriculture," adds her husband Uli Overmeyer.

The courtyard is composed by individual volumes, all with views of the garden landscape. The large volumes are constructed of timber and are themselves composed of smaller volumes with thresholds, intermediate and partial spaces that take up references to the neighboring buildings. The overall structure of Gärtnerhof becomes smaller and larger simultaniously. In the patchwork of facades there are different veneers made of re-used bricks. The spaces all communicate with one another across the yard; all annexable according to the seasonal and momentary needs of the residents and operators.

The Gärtnerhof is a cross between a garden and a farm; a charged island in the landscape. The garden is compaction, in the yard the garden experience is opened up and thus further condensed; it is a space of rural conjestion. The farm is so compact that life and work are immediately perceptible, that the operational processes are optimized. The farm has a closed energy cycle. Animals, houses, equipment, fruit, vegetables and people coexist in a dynamic, cultivated order, to the rhythm of the seasons, in accord with the laws of nature.

location: Krefeld
team: Anne-Julchen Bernhardt, Jörg Leeser, Laura Fuchs, Leander Lentner
client: GGK Grundstücksgesellschaft der Stadt Krefeld mbH und Co.
date: May 2021

In the Stadtbad Krefeld, everything is already there. Renewed with light interventions, it reveals itself an open, public incubation center for small businesses.
New spaces emerge through opening, adding or minimal subtractions; alterations all complimented with playful furnishing.
The formerly introverted building is—through a plethora of new entrances—made public.
There are cold, lukewarm and warm rooms; the diversity of climates serves a diversity of uses.
Rooms can be rented on a daily or monthly basis, with select by-the-hour rooms for special engagements.
The spaces are evenly divided into very small, small, middle, large and very large rooms—a fitting size for everyone.
Circulation spaces are shared and multi-functional; they foster run-ins and adjust themselves to the requirements of their users.
The gardens and the pools in block's interior create a magical atmosphere. The block becomes public, but this atmosphere is preserved.

The building is a ‘solitaire’ in a garden, surrounded by a wall. The wall is urban, programmatic and formal, taking communal uses and returning them to the city. To the inside, the wall encloses the garden for the children, who can play on the green, protected from noise of the city. To the outside, it provides public bicycle parking and car sharing, space for a public café and forms a new square, the ‘Körnerplatz.’ The Christuskirche church square thus receives an add-on across Schloßwenderstraße, capping its southern end. The resulting sequence of squares incorporates all the uses of the city - housing, education, movement, commerce and worship.

The building rising above the wall is a simple compact volume made of brick. With its façade (and the unique spaces it reveals) the building responds to its location in the city. The four common spaces each have specific qualities related to their respective sides: a café opens onto the new square, a shared living room faces the church square, a laundry room and open terraces face the residential neighborhood to the South, and a living/study room face the university library. Each of these spaces make their own distinctive mark on the otherwise regular structure of the brick relief façade.

In the building, storage rooms are not assigned to the individual apartments, as is typical. By pooling the required 4.5 m2 per apartment, and adding it to the 1,5-meter-wide hallway space, a new 3-meter-wide communal space is created. The individual apartments thus become a cluster apartments. The hallway—a place of communal living in historic housing typologies—is a multifunctional space. In addition to storing items that do not fit into the apartments (racing bikes, snowboards, surfboards and suitcases), larger communal items can find a place here; kicker, work tables, large televisions, sofas, and oriental carpets turn this space into a living room. The four-to-seven residents of a hallway community can decide collectively about how to use the room, allowing the hallway to reflect the community it serves.

status: project
program: New National and University Library
location: Ljubljana, Slovenia
team: Anne-Julchen Bernhardt, Jörg Leeser, Matthias Hoffmann, Wolfgang Zeh
date: March 2012

Library is a place of permanence and continuity. It is rooted in Roman remains. Its geometry is based on the universal orthogonal grid of Roman colonial planning. Yet it is a place of change, openness and progress. As a laboratory of knowledge it nurtures scholarship and community.

Here time is no longer linear but becomes simultaneous. Library melts time into a single presence. There is no antagonism of old and new, no ideological compulsion to destroy and overcome. Whether we rest on the shoulders of giants or whether giants stand in our way, the future will know. Library pays tribute to the rich urban fabric of Ljubljana and complements Plečnik's city with humility. It balances between civic grandeur and modesty. To be the New National Library and yet one among many buildings Library is just slightly detached from the city block, an almost stand-alone monument. Almost. Its distribution of building mass emphasizes Zoisova Street as an "University Boulevard" and adapts in scale towards French Revolution Square. Both entrances are marked with recesses and grand stairs. The gap between the city block and Library opens a pedestrian path to cross the courtyard. Access of vehicles for loading, the handicapped, and restricted parking is also permitted here.

Library expands the limits of typologies, it is an open plan building yet contains six distinguished public rooms. Free access shelves and restricted archive areas blend into a continuous space. Physically they are separated by glass walls. Horizontally the public rooms have no limits, the rooms are defined by their voids and their natural light.

A structural system of waffle slabs supported on cores and cross-shaped columns allows large spans and a minimum of piled foundations. The impact on the archeological remains is minimized, the flexibility of the library space is maximized. Library is an open building, the entrance level is a 24h zone. Five reading rooms and the multi-functional hall are spread across the floors. They create zones of distinct character, each with individual spatial qualities. The user can retire to his place of choice. In the special collection he will be among Roman ruins, in the grand reading room underneath the sky. The multipurpose hall is situated on Level 0 and can be used independently from the library.

Library is a place of presence and identity. It is a physical space, it has weight but is still floating. It defines space but stimulates interpretation. Library is multi-folded space.

Schloss Türnich is a unique spatial structure made from architectural and landscape elements. Together, they form a system of particular pieces: the castle, the moat, the French garden, the English landscape park, the mill, the forrest, the avenue and the agricultural land. The elements are not necessarily connected to each other and old connections are often interrupted by new elements.

This generous distribution of partially disjointed scenes - a recurring phenomenon throughout the history of the castle - is the main feature of the situation. The changes in the castle complex should therefore do justice to the special nature of the place. The connection between the castle, the village and the surrounding agricultural land should be achieved subtly via indirect connections; maintaining the autonomy of the subspaces and underlining their special atmospheres.

date: February 2020

The Strobbe printing press is an important part of Izegem's architectural identity. This building is thus seen not merely as a resource for sustainability, but also as an important example of a proud industrial building tradition. The essence of this building is the starting point for the ‘Cultuurfabriek’—the ‘Volkshuizen’ of Izegem. It is a house which belongs to everyone - a symbol of the city’s re-appropriation.

The Cultuurfabriek unites the previously separated institutions of archive, library and academy within the large body of the Strobbe printing house. The result is more than the sum of its parts, for the overlap of institutions creates a unique social entity in its own rite. Through the large, shared event space, restaurant/bar/cafe and small exhibition space, both the peculiarities of the individual institutions and their thematic harmony are experienced together.

The transformation of the Strobbe printing press into a culture hub is achieved with only minor interventions and additions: the building is understood as a large open structure in which existing qualities are discovered and enhanced. The structural beauty of the space is exposed, the size and essence of the rooms made tangible, while a few new large installations organize and upgrade the space. These space-making additions are infrastructural in nature, always accessible, and contain secondary rooms underneath or inside. These additions serve as actors in open space, concentrating and provoking action.

Towards the goal of sustainability, the building is regarded as a complete system in which all individual parts contribute to the success of the whole. The conversion of the existing building saves resources, the grey energy bound in the building is reused, and superimposition of program allows for a minimum of new construction. Preservation goes before demolition, strengthening before replacement.

Overath is a small town on the periphery of Cologne's suburbia. Rationator is a detached house for a family with 3 children.
Sited on a stretched building plot along the bank of the Agger River, the house is threatened by floods up to 2,5 m above ground level. Thus the design anticipates possible flooding with a choice of flood resistant materials and construction techniques.
The clients represent the typical family who dream of their own house, but have a limited budget. Rationator acknowledges this predisposition with a choice of communication strategies and profound typological exercises.

client: Stiftung Einfach Wohnen
date: December 2020

The new Rotbuch-settlement is composed of an unequal double; two house ‚characters‘ that complement the colorful image of the neighborhood.

The larger, angled townhouse is oriented towards the street and forms a generous green corner against the intersection, while the smaller garden-house joins the group of second-row-houses placed in the topography. Together, these characters mediate between the scales of the surroundings, continue the open building structure and seek a self-evident presence in the midst of the beautiful vegetation.

The townhouse is developed as a dense package of rooms with common spaces of various scale and use. Floor communities of different micro apartment sizes (1-, 2-, and 3-rooms), intentionally located next to each other create mixed-age, mixed-living-model communities around South-facing, shared living rooms. The living spaces emerge from within the structure of the building; open spaces supplemented only by the adjoining smart-closet bathrooms.

The garden-house leaves space for the large existing Larch and has a clear, simple structure and layout. Kindergarten and Day-care share the first floor along the garden with morning sun, while above are two maisonette-cluster apartments with a communal terrace.

The heart of the new ensemble is the collective courtyard between the two buildings. High-crowned trees shade the gravel square. Connecting the two access roads, it offers space for communal activities and meetings, becoming the center of gravity for the settlement.

Balthasar Neumann Preis 2007 shortlist

As a non-hierarchical, uniformed, infinite and flexible space FRABA Sp. z o.o. is a metageneric production plant. FRABA produces electronic components for the automation industry in a non-automated manufacturing process. The products are hand assembled in small series. The assembly consists of tables, shelves and trolleys.

On a tight gross budget of 580€/m2 a prototype plant for future expansions around the globe is developed. The design reacts to location specific construction and logistic conditions for each site.

In Poland there is a sufficient supply of timber at considerable low costs compared to the conventional steel structure. With a global steel market overheated by Chinese demand and the affordable labour costs in Poland, a lightweight timber structure becomes reasonable.

The structural system consists of a 52m diameter 60°solid web beam grid. It rests on 19 17cm diameter stressed steel tube columns with a clear span of 9,70m. The shell is made of prefabricated insulated plywood elements, 14% of the roof is covered with triangular skylight domes. The top surface is aluminium coated bituminous roofing membrane. Gross floor area is 2069 m2 with an overall clearance of 4,5m. The building has mechanical and conditioned ventilation, Skylights are specifically designed for perfect daylight assembly conditions and avoid heat gains during the summer.

The circle is an optimized box. In comparison to a rectangular building of the same volume it has less surface, which in addition to saving energy, reduces construction material by up to 13%. The triangular grid minimizes the constructive complexity while offering a maximum of possible layout variations. The dimension of the triangular grid is adapted to the needs of the company; optimized for the client's production process as well as for possible future uses.

net floor area: 53.826 m2
client: National Library of the Czech Republic, Prague
structural engineer: Jürgen Bernhardt, Cologne
date: September 2006

The building of the New National Library marks the western edge of Letenská plain. Even though building mass is added to the area, the wide and open terrain is preserved as a multifunctional urban space. Corresponding to the monumental dimensions of the urban context, the New National Library rests as a simplistic volume on the extended gravel surface of Letenská plain. Oriented parallel to the open area, the building has a square footprint of 97,20m2 based on an 8,10 m square grid. To the north, an open plaza provides the main entrance for pedestrians. To the east, the library café, which also serves as an entrance, features a terrace looking onto the infinite gravel surface of Letenská plain.

The New National Library is a hybrid typology between utilitarian functionality and public grandeur. Sixty percent of the floor area is used solely for storage, with twenty percent of the floor area is open to the public. The presence of 10 million books creates a monumentality by sheer number, similar to baroque libraries, where visitors and employees are completely surrounded by books. With generic typologies such as supermarkets as a model the scheme juxtaposes the programmatic necessities of separating magazine and public spaces with the baroque approach of universal presence. The enormous size and complexity of a National Library reflects into simplistic spatial matrix.

In plan the 97,20 m deep open space is structured by supportive cylinders and voids in the floor. The voids connect spatially to the lower floors, which are mainly used as magazine spaces. The cylinders also provide controlled natural light through circular patios. Four cores contain vertical circulation, fire escapes, public and freight elevators with car capacity. Upper floors have 6,75 m clearance, lower floors 2,33 m. The neutrality of the system allows for a wide array of possible layouts. Essentially the ground floor contains public services, the first floor reading rooms, the second floor administration and public services. Restaurant and auditorium are also on the second floor.

Each upper floor is accompanied by a secondary lower floor (inverted mezzanine) that provides storage space for the public.

The peculiarity of the site is its production of contradictory phenomena. The nearby highway and industrial buildings create an audible world characterized by their unpleasant loudness while the left-over open spaces have fostered a bucolic wilderness, complete with an idyllic lake.

Through the insertion of a residential quarter, ‘Am Albertussee’ creates a new mixture of city and landscape. Here, the synthesis of two contrasting urban morphologies—the open modernist cityscape and the closed compact “European city”—combines the best of both concepts.
The scenic nature is emphasized by the flowing spaces of modernity, while the interior spaces of the solitary blocks protects the inhabitants from the noise of their surroundings.

The outdoor space is an inclusive permeable public space, serving both the residents and the greater population as a place for meeting and leisure. Not only does the transition between the pastoral south and the urban north mark relationship of nature and culture, but it gradually introduces inaccessibility protecting scenic biotope from and for the densely programmed public space.

date: February 2020

The ‘Dragoner Areal’ inspires a strategy of preservation and continuation. Its spatial and atmospheric density, richness and diversity lend this strategy its starting point, goal and content. This diversity is a product of a duality: a friction between the site’s 19th century army barracks and the Wilhelminian urban texture which has grown up around them. In between the rigid geometry of the barracks and the amalgamated interior of the Berlin block, a disorderly, yet lively hinterland of subordinate outbuildings has developed. To create a truly mixed-use urban quarter, the integration of these existing commercial and cultural uses is paired with a clarification of the barracks’ inherent architectural characteristics. By taking up its already in-progress transformation, this monument of the past becomes the living heart of future development.

The frayed sequence of courtyards along the block interior are strengthened, capped or enlarged to form a series of more definite courtyards and living ensembles. Public functions are re-oriented or added—supporting and introducing block life—while the reclaimed order of the barracks’ structure introduces clear entrances, sightlines and throughways. This structure is therefore maintained, with special attention given to the re-fortification of the three traditionally open spaces: the central parade ground and the two practice fields. This is achieved not by reconstructing the missing wings and head buildings, but by replacing them with a diverse cast of more contemporary structures. Residents and users have then direct access two the two practice fields, which—restored to their original proportions—now serve as an urban garden and work yard, and the parade ground—now partially re-appropriated into a central plaza.

net floor area: 45 m2
client: Julie & Michel Vandenbroucke
costs: 100.000 €
date: July 2011

The Guest House project is based on BeL's personal experience as guests and temporary inhabitants of the Vandenbroucke residence.

Built fifteen years ago in the style of a fermette, the residence has been dramatically renovated by 51N4E. Their radical transformation opens the conventional plan to a multitude of functional programs. Gutting the existing house and adding an exterior space enclosed by a steel wall, the boundaries of exterior and interior are blurred completely. Domesticity is given a new significance, the fluid spaces offer a multitude of interpretations. In its ambiguity the house is an architectural manifesto and a home at the same time. It is a spatial portrait of the residents, an open house, happily awaiting guests.

With a guest program in mind particular functional limitations of the transformed residence become evident. Guests outside of the owner's personal realm intrude upon the latter's intimacy and have demands for their own privacy themselves. Two essential architectural shortcomings emerge from this programmatic friction.

The Guest House project enhances the functional performance of the house to meet the extra demands of a guest program. Additional space is generated within the existing building. The Guest House is not a detached or added annex but expands into the interior. It is extra space discovered inside of the building. It enables independence of individual users, supplying alternative spaces to be appropriated by guests and hosts.

The Guest House is a miniature house hidden within the existing building. It's a parallel realm of complementary space waiting to be occupied by either guest or host. It offers a diversity of rooms in a spatial continuum. It is small in scale, yet a whole new universe. Searching for the remaining voids left by 51N4E's transformation, the Guest House exhausts the building's volumetric capacity. With a minimum of alterations it strives for a maximum of space, retrieving surplus volume to residential use.

Challenging the visible and invisible thresholds of the occupants, the Guest House emphasizes their modes of dwelling and pushes the margins of cohabitation.

Marceddi, Torre Salinas, you click it on the browser and fall on planet Earth from the heights of the stratosphere. Flying in on forests, sea, lagune, zooming into spontaneous trails between groves and fields, unplanned open areas along the coast, hidden camping facilities, scruffy mountains, draught areas, stray animals, rivers, curves of silver, fishes, boulders, dust. The entire island is full of beauty, even in beautiful sad places such as Marceddì, or the desert-like splendour of the lagune in Torre Salinas. From these simple observations and the use of Google Earth we developed the idea to produce new aerial photos of the two places. These aerial images - rather paintings than plans - intend to be new realities, assumptions of a future landscape, parallel to the current situation.

We travel through Sardinia in search of our own modern Arcadia.
Everything starts with the landscape: cultural and natural landscape.
The landscape is Sardinia's asset.
The landscape rather than buildings will serve as a catalyst for identity and urbanization.
The landscape becomes richer: it grows instead of disappearing.
The landscape saturates in its qualities: it becomes greener, bluer, wetter, dryer, thicker, airier, etc.
The consequence is the bonding of foreign and native, work and free time, nature and culture, good and bad.
Tourists and Sardinians live together in the same place: minimal separation and no boundaries
Tourism in a real Sardinia: it's not a theme park. All material comes from the site.
Minimal impact with moderate alterations corresponds to feasible economic principles.

Everything starts with aerial composites of the existing.
A thorough analysis in detail leads to the recognition of the existing qualities.
The image and the landscape are not identical. But once having reworked the image we've already affected the landscape.
The image, and consequently the landscape, is quantifiable.
It is about reaching critical mass to understand the relation of the landscape and its use. (The point when a landscape becomes periphery, a tourist village a sprawled strip, etc.)
Local retouching: all material comes from the site.
The result of the work is a perfect aerial image, we have found Arcadia, an idealized landscape.

After converting the 1950's department store into a modern residential and commercial building the only remaining retail spaces were located on the ground floor. The first floor is home to a public recreational room where children whose parents are shopping can be cared for by senior citizens; this space can also be reconfigured to form an office or a surgery. The target groups for the two residential floors are elderly and handicapped people who live in the city and wish to enjoy the advantages of unassisted living.

In the second and third floors there are eight apartments in all, which can be used individually or as a residential cooperative. In order to retain the openness of the former department store, the floor plans are divided only by the addition of core sanitary modules and moveable wall elements. Each apartment has a fully-glazed inner courtyard. The composite thermal insulation system, necessary to keep energy levels low, includes a newly developed light-plaster, which responds to sunlight with the aid of inset glass beads.

The 7/8 house is an extendable house, designed to accommodate different living arrangements. The internal structure produces a range of ‘houses’ from the 4/ 8 house (106 m2) to the 7/8 house (142 m2.) Within the finished shell, light ceilings and partition walls can be constructed of wood. This makes do-it-yourself changes possible: if another child comes, one of the air spaces is transformed into a new room over a long weekend. Once the children are out of the house, it can become smaller again and provide space for a second, independent ‘granny’ apartment. In this 4/8 + 3/8 house, the living area of the core house is 86 m2, and both units have their own garden access.

date: April 2012

A proper city has a marketplace, but when civic pride and prosperity allow it, a city affords itself a loggia. The city rises from the mundane to the sublime. It celebrates itself, urbs becomes civitas. A loggia is a universal building, where commerce, politics and culture meet. It embodies urban life.

The twelve historic marketplaces in South Westphalia are getting a common loggia: the Loggiavélo. It is vehicle-like building, driven from town to town by the twelve mayors of the participating municipalities. The mayors are ecological and sustainable motors, consuming not fossil fuels, but renewable raw materials. If a motor is prevented from riding by important appointments, they can be replaced by an equally environmentally friendly representative.

The journey from town to town, powered by the physical strength of the citizens, is an indispensable part of the Loggiavélo. This is where the mayors get closer, where cohesion is tested, where a community is born. A bond is formed between the twelve cities, fortified along the way by picnics in the beautiful South Westphalian landscape.Through sweat and toil, the legend of the muscle-powered community town hall is born.

When the Loggiavélo is not being used for locomotion, it stands in the marketplaces of the participating communities. It stands directly on the pavement, a neutral space for all urban functions. Music can be played here, brochures can be distributed, and people can fortify themselves with a pilsner. This is as much a place for historical speeches as it is for baked waffles; revolutions can start and cooking recipes can be exchanged.

Each of the twelve trolleys is equipped with luggage boxes, giving the Loggiavélo a total storage capacity of 450 liters. There is room for folding chairs, leaflets, electricity, computers, a music system, crockery and a waffle iron. Decorating the "frieze" of the loggia are the coats of arms of the participating municipalities. At night they glow, creating a beacon of civic pride.

The Loggiavélo is a vehicle of lightweight construction, aerodynamics and innovative technology, demonstrating the technological expertise of the South Westphalia region. The welded aluminum lattice tube frame of the Loggiavélo is a weight-optimized space frame; the wall and roof are covered with a printed Dyneema fiber-reinforced foil laminate. The sides are perforated to reduce the area exposed to wind, and all parts are sewn together to be waterproof.

To support the mayoral forces over the breathtaking topography of the Sauerland, the mechanical crank drive is electrically amplified by 250 watt Bosch center motors. High performance batteries can be charged by recuperation. The Loggia receives steering through a "drive by wire" system, operated by the front left driver. This system and electronically controls all wheels individually. Similar to a tank, the Loggiavélo steers by accelerating or decelerating the electric motors on the two sides of the vehicle in opposite directions, and braked with synchronized hydraulic disc brakes.

status: in progress
program: cooperative housing
location: Neunburg vorm Wald

structural engineer: Dr.-Ing. Arne Künstler, Frankfurt
client: 9BÜRGER eG Wohnungsbaugenossenschaft i.G.
date: July 2019

Arising in relation to the landscape, this new ensemble is composed of three parts: house, shed and yard. It is a cooperative living project for people over 50; people who want to begin the next phase of life in a lively and social environment.  

The house consists of 19 living units, a common room with kitchen, a shared bathroom and a guest room for visitors. Opposite is the shed—a large simple roof—for storage and work. Between these two structures is the communal yard. It is a space of movement and unplanned encounters: neighbors pass by, hang out, or repair their bikes; all the action is here.

The building is accessed via a long arcade, ramped to match the topography. The use of standard German accessibility standards is here formalized into a terraced social space and the structural backbone of the building: the residential units are stepped down along the slope of the ramp. The house is likewise staggered in plan, with the different flat sizes arranged according to their size. Facing south towards the arcade, each flat has a glazed, unheated veranda. It serves as a terrace in summer, enlarges the living space in the transitional periods and creates a threshold space between the communal arcade and private living quarters.

099 AL29UC Conversion, Cologne 2014

status: completed
program: conversion of a 29th floor penthouse into a photographer's office
location: Cologne
team: Anne-Julchen Bernhardt, Jörg Leeser, Conrad Kersting, Christiane Schmidt
structural engineer: Jürgen Bernhardt
client: private
date: September 2014

At 134m high, the Uni-Center in Cologne is one of the largest residential high-rises in Europe. In addition to 1000 apartments, it has several offices and service areas. One of these, the 250 m2 penthouse atop the lowest wing of the building (29 stories) had been divided into 5 office units. With the addition of a few structurally strategic elements, dividing walls could be removed, unifying the penthouse space. With the exception of the neutral gray bathroom and technical room, the office is now composed of a fully glazed large room with a single core of exposed concrete. The glass facade was completely replaced by energy-efficient elements and provided with a large sliding system which opens East onto the roof garden. 

The conversion deals with perspective as a symbolic form. An approximately 90 cm high platform takes up most of the space. Under the platform there is space for the large number of cables which dominated the room before the renovation; these are now combined with the existing core and hidden discretely behind the bookcases which run along the edge of the platform. This simple move divides the room into two spaces: a low-lying zone along the facade and a wide, open area above. Below is the library, storage, and tea kitchen, while above are the permanent workspaces, meeting tables and a sitting area. The floor of the platform is covered with a specially designed and manufactured carpet, which—in reference to oriental patterns—contains ornamental elements such as the floor plan of the Uni-Center, the coat of arms of the building owner’s birthplace, and maritime motifs from the Gaudi tile used in the tea kitchen.

In raising the floor 90 cm, a breathtaking panoramic view extends over the balustrade of the roof garden—at a considerable 115 m—to the horizon. The world is at your feet.

141 Ehrenveedel Competition, Cologne 2017

text

status: competition
program: housing, workshops, retail
location: Ehrenfeld, Cologne
team: Anne-Julchen Bernhardt, Jörg Leeser, Laura Fuchs, Mariel Kaiser-Crompton, David Leber, Malte Wilms
client: Aurelis Real Estate
date: November 2017

The neighborhood of Ehrenfeld, with its characteristic mixture of small-scale residential/mixed-use development and large-scale industrial areas, is developing to serve future needs. However, in today’s economy, continuing the small-scale development of the area is just as impossible as preserving fragments of the site’s former freight depot. The project thus places a special demand on the architecture for the creation of a site-specific identity: the uniqueness of the place must not be lost in anonymity. The site, with topography rising toward the South, is traversed lengthwise by three axes: a neighborhood access road to the North, a bike-pedestrian through-way, and a green corridor sloping down from the train tracks to the South. Neighborhood alleyways connect these axes cross-wise, allowing for a central residential courtyard, while the zoning plan calls for the integration of commercial uses along the Northern neighborhood street.

These conditions—the interaction of different social spaces, topography, required noise protection, and planned building volumes—call for a mixture of building typologies to compliment the various open spaces and maintain the mixed-scale character of the neighborhood. Buildings A, B and C are therefore not only different from one another, but are further subdivided to finely tune relationships between public, semi-public and private areas.

Along the neighborhood street in the north, the buildings are arranged directly adjacent to the street space, creating a threshold-free connection to the public space. The neighborhood alleys to the east and west are activated by the entrances to the residential units of Buildings A and B, while low-threshold front areas of the ground floor flats create a transition from the public to the private sphere. The topography creates clearly defined transitions to the flat inner courtyard, which sits 1,5m above the ground-floor units to the North and West. Building B solves this challenge with a plinth, —at about the same level as the courtyard—accessible from the North via a staircase and from the South at ground level. Building A, on the other hand, mediates the height distinction through a series of double and split level units, all containing internal stairs. This strategy is picked up by building C, which is entered directly from the pedestrian and bicycle path, and features private gardens arranged another 1,5m up green slope to the South.

The ensemble is bound together by a canon of industrial façade materials and the central courtyard, the social heart of the area. With direct access for all residents, a gradation of secondary public thoroughfares and semi-public inner block areas, it invites communal use. Elevated off the street and lightly shielded from the bike path by trees, the courtyard features a water-bound sand surface, making it an explicitly informal grandchild to the open industrial yards of the past. The yard is protected from the sound of passing trains by the high wall of building C, while the terraces of buildings A and plinth of building B are just high enough to provide the yard with informal seating. The three buildings—with their ample balconies, roof gardens and arcades—work together, forming a protected, lively atmosphere

125 Euroforum Competition, Special Prize: Façade, Cologne 2016

status: competition. special prize façade
program: housing, workshops, retail
location: Mülheim, Cologne
team: Anne-Julchen Bernhardt, Jörg Leeser, Christiane Schmidt, Matthias Hoffmann, Michel Kleinbrahm, Gina Rauschtenberger, Leonard Palm, Wolfgang Zeh
client: Euroforum Nord GmbH & Co. KG
date: January 2016

The two solitary structures--containing a total of 350 dwellings--inherit their scale, and many of their characteristics, from the industrial architecture of the neighborhood’s past. They maintain a strict structure in their construction and design; the repetition of rational elements lending a calm, impassive presence to the simple building volumes.

The urban outdoor space is diverse and lively. Ground-level residential studios strengthen the creative potential of the area through the mixture of living and working. The urban exteriors stand in contrast to the paradisiac shared interiors, which also offer a habitat for animals and plants. All apartments have at least two types of light and views; looking out, the space is lively and urban, while looking in, it is tranquil and green.

The clear separation of the outside and the inside is reflected in the design of the façades. The street-side façades are clad with prefabricated concrete. While their horizontal structure is homogeneous with soft repetitions, the individual levels differ significantly from one another. This vertical differentiation creates a sculptural relief with diverse and invigorating shadows. In the courtyards, volumes are projected to maximize the surface of the block. The façades are thus uniformly designed as wooden elements; their warm and simple forms adding to the peaceful character of the courtyards.

status: completed
program: adaptable trade-fair-system
team: Anne-Julchen Bernhardt, Jörg Leeser, Adria Daraban, Max Schoeneich, Wolfgang Zeh
gross floor area: 3 - 200 m2
client: FRABA AG
date: 2009 - 2014

Evolving from DIN display system ISO provides improved flexibility, rapid assembly time and minimized payload. Presented on a worldwide campaign the ISO universal system has to comply with numerous international standards. ISO is nomadic architecture, it features lightweight elements, easy to carry and easy to assemble. Traditionally fabric is used to create shelters, ISO deploys a curtain/carpet made of customized injection molded polycarbonate snap-on tiles. ISO is a non-spatial concept. The elements can be applied in an infinite number of configurations on a multiplicity of trade fair lots. The possible organizational patterns are based on rules of proximity. Depending on the specific context the client can choose from a large array of possible set ups.

Iso is an attempt at nothingness. The spatial presence of the individual objects is reduced to the bare structural necessities. In an almost tribal simplicity, illumination is provided by lampposts. Tables and chairs have an intermediate height between chairs and bar stools to allow informal communication.

The grandeur of ISO's delicateness is a remedy to the barren environment of trade fairs. ISO is a satisfactory combination of austerity and pomp.
