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.

Kölner Architekturpreis 2014, Honourable Mention

Ehrenfeld is a quarter of Cologne where living and working are traditionally combined. Typical for this area are small workshops in the backyards of street front houses. In this project, one of these small industrial halls, a protected former blacksmith's workshop from 1902, is converted into a living and working space for a small family and their business.The building consists of a small two-storey office house and a 10 by 25 m sawtooth-roof hall. The relatively small rooms of the office house are converted into an intimate living area for the family with bedrooms and a central open kitchen. The big hall is used as a free open space that can be used for working and living. At special occasions it can be converted into a showroom for the company's products: BMX bikes.

The protected building, which was in a very bad condition as a result of being out of use for decades, was completely restored in terms of structure, insulation and surfaces. Original and new architectonic elements and surfaces blend together to produce a timeless atmosphere, neither old nor new.

The main spatial intervention consists of cutting out a new patio from the volume of the industrial hall. One space is converted into two: an interior and an exterior space.
The interior space that used to have an almost claustrophobic atmosphere, the only connection to the outside being translucent skylights, is combined with an exterior space of light and air that can be used as an outdoor living room.

The two spaces are connected via a big sliding door that can be opened over the full width of ten meters. Thus, the separation of the rooms blurs in summer – living and working can take place inside and outside - whereas in winter you can watch the rain and snow fall into the patio from inside.

The area between Vogelhüttendeich, Rotenhäuserstraße, Jaffe-David-Kanal and Aßmannkanal has special qualities: it is a landscape in the city. Wilhelmsburg, the Elbe island, originally sparsely populated with its hydraulic engineering can still be experienced here. The canals and many allotments give the area a scenic atmosphere. The pier with its beer garden at Vogelhüttendeich is a place in front of the city but not yet in the countryside. To the west lies the Reiherstieg district, the epitome of a dense, culturally mixed neighbourhood. Here the blocks stand sharply defined as bodies in the landscape, forming a closed space of intensive urban life. In the commercial area south of the planning area, garden elements of a suburban idyll can be found. This temporal, spatial and typological fusion of the landscape with urban and industrial fragments is fundamental to the design.

In Wilhelmsburg, landscape and city meet like living and working. Different typologies stand side by side without constraint, they use and reinforce the qualities of the area, individually or in context. The encounter of different building types with diverse open spaces creates a multitude of independent subspaces. We create urban density through architectural typology. Within a plot, the individual buildings are coherent and create urban space in their specific design.

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.

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.

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.

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.

The scheme is based on Edward T. Halls theory of proxemics, a study on the individual's need for personal space. To guarantee privacy within an open space, confidential conversations need to be protected by minimum distances. The proposal embraces the conflicting requirements of openness and privacy and encourages customers to ascend to the upper floors.

A low-ceilinged Rustico welcomes the customer on street level. The ground floor is open to the public 24 hours a day and houses several ATMs. During business hours an extra-wide spiral staircase opens to a spacious Piano Nobile. The structural system of the building consists of 13 slim columns and 5 waffle floor slabs. A service core contains ATMs, a staircase and an elevator.

Due to the cooperative heritage of the Sparda Bank the project indulges in humbleness.

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.

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.

The result of car-oriented city planning, Düsseldorfs Kö-Bogen’ area no longer satisfies the demands of a contemporary, publicly perceptible urban space. In particular, the intersection of Hochstraße, Berliner Allee, Schadowstraße and Hofgartenstraße, as well as the crossing streetcar lines, create a public space inadequate for the needs of a pedestrian-oriented city center: offers for cyclists and pedestrians are missing and Gustaf-Gründgens-Platz is isolated by parking ramps. It has been reduced to an underused, mono-functional theater square. This urban planning proposal follows a integrated, yet selectively targeted strategy to transform the site. The negatively perceived compression of urban dynamics, caused by the noise and exhaust of road traffic, and the barrier-forming traffic infrastructure, are reformed into an exciting, comfortable and livable urban space. The existing dynamics of the site are not negated, but absorbed. Nuisances and hazards are eliminated through the clever arrangement of new features and the re-appropriation of the old.

By removing the traffic from the overpass and routing it underground, or integrating it into the surrounding city, a new piece of public infrastructure is created.  The ‘Tausendfüßler’ (centipede) creates a high-quality outdoor space with weather protection unparalleled in Europe, creating a distinctive new feature for Düsseldorf. The new space is an amplifier and transformer of adjacent uses. Connected to ground level by six new vertical accesses, the Tausendfüßler creates a two-level horizontal sequence of different programs. This space connects the Hofgarten, Berliner Allee and Immermannstraße with a marketplace, outdoor theater, cafes and play areas for children and adults.

Gustaf-Gründgens-Platz will now be connected at ground level with the new open spaces surrounding it. The surface of the new urban space will consist of exposed aggregate concrete slabs in four light, slightly varying shades of gray. The slabs form a generous polygonal units with surfaces treated to give them the shimmering mica effect typical of gneiss. Two low points are both water fountains, square drainage and light sources for the parking garages below. The subway station is connected to the ground surface by an opening including a staircase and is related to the other public spaces.

Living in the center of the city, in close proximity to the cultural center and the Hofgarten, is a central component of the design concept. Gustaf-Gründgens-Platz, which is given a new presence, is enlivened by residential use and enhanced in its function as a public space. To this end, two new structures replace the former buildings at Gustaf-Gründgens-Platz and Tuchtinsel, while a third new structure completes the constellation. The structures each consist of a 25 m high base and a 54 m high tower. The northwestern building is connected to the elevated streetcar station, while the southern building spans the Tausendfüßler. To the north, the buildings’ 6 m high arcades open directly onto the square, concentrating commercial and public uses. Here, the apartment buildings’ lower floors participate directly in the urbanity of the square (children's laughter, latte macchiato, ice rink in winter, water games in summer), while apartments on the upper floors bring with them a view over the city. For the residents, the Hofgarten is perceived as a front yard.

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.

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.

The transformation of the ‘hafen’ (harbor) into HafenCity is a challenge. Where once large-scale mono-functionality of harbor basins, crane facilities and quay sheds dominated, a small-scale mixed quarter is now emerging. This project seeks to weave these strands—of place, identity, function, construction, space and material—together. The industrial grandeur remains tangible; the openness of the formerly mono-functional large remains present in the small-scale mixed.

This begins with the structure of the building, a hybrid of skeleton and load-bearing bulkhead construction. This three-nave masonry pier structure is the unifying essence of the building, binding together space, material and façade. Its neutral spatial structure enables the construction of 30 different flat types with specific requirements for divisibility, switch-ability and, in some cases, very determinate dimensions. Changes in family or occupant structure throughout the entire house can thus be accommodated without structural interference. Thanks to short spans, composite timber ceilings and prefabricated elements are possible, reducing carbon-hungry materials and allowing for easy re- and deconstruction. On the facades, the structure is reinterpreted as functional ornamentation. This restrained narrative is contextual: it is a masonry building on the harbor. Was there before? Is it a converted warehouse building? The visible structure, the ordinariness of living and its prominent location make for a quietly peculiar building.

The terp-formed pedestal facing the Versmannstraße and the promenade along the wharf below result in the building’s two ground floors. The plan development follows, subtly differentiating the building into two volumes: an L-shaped structure—eight stories to the North and five to the South—sits atop the terp, while a four-story cube faces onto the promenade. Offset by half a story, but with an aligned parapet, they form a split-level building which is nevertheless legible as an independent body; first cut in, then exposed. The upper ground floor is hidden from the street by its neighbor—the communal entrance courtyard is reached through a passage—while the lower ground floor perforates the terp wall modestly, connecting it with the promenade. Here the 1,5-floor high ‘Quarter-pipe’ communal space is accessible from both sides, constituting the first of the buildings various communal spaces. Others include a play place at ground level, a communal kitchen/terrace and multiple roof gardens. These spaces, the two volumes, and the apartments themselves are united through a single external stair: the social heart of the building. The staircase creates an address and an identity, offering easy ascent through the split levels, casual interactions, and —from the 4th floor upwards—views onto the Hamburg harbor.

Re-densification of this block at ‘Mauenheimer Gürtel’ is enabled by the site’s good connection to public transit, the existing retail and supply infrastructure of the neighboring ‘Nippes’ district and, in particular, the proximity of recreational space.

First, the interior of the block is enlivened with the insertion of slim ‘entrance’ slabs into the block at the North and South. The first floors of these slabs are open with 3.50 m clear height; bicycles can be parked here, and the block community gains meeting room and a workroom. Further interventions to the existing building are minimized, with only one apartment converted to ensure an escape route, while new apartments are supported above the existing building with an independent structure, giving the whole block 3-4 extra floors of living. The new building is designed as a timber modular construction, with each apartment consisting of five prefabricated modules. These modules can be transported by truck, while the support structure is delivered largely finished. Lifted over the existing building by crane, the erection of the structure takes only a few days.

The apartments themselves are planned as open-use, accessible 100 m² four-room apartments. The rooms can be easily divided, creating a 7-room apartment from four modules. The very homogeneous existing building (almost only 1- to 2-room apartments) is thus complemented and hybridized by a differentiated and flexible resident population of families, student and senior living communities.

Plot 3 is composed of three residential buildings: the ‘Liège’ tower, the ‘Gradient’ building, and the Zigzag house. Each has access to the communal courtyard and features a public or communal roof function. Most prominent of these is the basketball court, which crowns the gradient building. Accessed by a public staircase between the Liege tower and the gradient building, it is connected by a setback at the sixth floor of the tower to ‘Park Fiction 2.0’ and the rooftop restaurant of Plot 1, completing a network of public roof spaces.  

The 11-storey Liege tower is a small high-rise building; it lives from the flats' view of the city. Each floor has four units, oriented to one side, with additional sunlight and views provided by its characteristic projecting winter gardens, which function as balcony in the summer and additional room in the winter. At ground level, Liège is set back from the street, creating a small square. The 24-hour shop here has a large canopy reminiscent of the old Esso petrol station. The square preludes the ascent upwards to the public roofs, while the half-height setback at the 6^th floor enables the connection of basketball court and Park Fiction 2.0. At this junction a large penthouse, a common room for indoor activities or a superintendent office can be created

The Gradient building features flats of different sizes, accessed via arcade. The flats get progressively larger towards the corner, creating a surreal perspective effect; a kind of trompe-l'oeil. The motto is not ‘one size fits all,’ but ‘one size for everyone.’ To exploit natural light, the largest flat inhabits the corner, while the arcade is pushed back from the East façade, creating a private threshold and balconies. To the West, mini balconies enjoy evening sun over Taubenstraße and foster interaction with the street.

With a communal children's play area on the roof, the zigzag house completes the ensemble. It cleverly exploits spacing to look in all directions. It is a three-story building with a twisted floor plan; the flats have qualities that are otherwise only possible in a free-standing building. They are designed to be open to different occupancies: residents can live or sleep facing the Kastanienallee as well as the street. The balconies and loggias provide deep streetscapes or catch the western sun on the courtyard side.

date: March 2011

The human has always been moved to explore the cosmos; it is one of the oldest cultural fixations of civilization. As she contemplates the universe, the individual is searching for the deepest grounds of her existence. Here the intellect is developed; by curiously looking into the universe, man became a thinking being. In our conceptions of the heavenly bodies—their mechanics and their mathematics—thought meets the sublime. World-harmonic longings, hypotheses about the God-givenness of Nature, assumptions about physical determinism; man constructs the world, a self in search of knowledge.

The spherical gas container is not a building but a technical unit. It is constructed, not designed. Its austere beauty is based on its monumental construction, unintentionally (and thus more so) impressive.

The new Galileum Solingen is not a building but an instrument for communicating and exploring the universe. The grandeur of the technical cultural asset meets the grandeur of astronomical science. This is an ideal combination. It makes one shiver.

Adding the new to the old creates a symbiotic structure, both preserving the dignity of the existing structure and lending charisma to its new function as an observatory and planetarium. The result consists of two essential components, the sphere and the bar. Brushing eachother in the foyer, the bar provides subtle access to the planetarium—a half-spherical volume supported by spokes, off-center within the sphere of the gas container. The impressive interior volume of the container is opened—at the top by an oculus, and at ground level by the removal of the old steel shell—and becomes the Galileum's entrance way.

The way to the stars goes first through the underworld. Where the access road and the footpath meet, a flight of steps cut into the ground leads into the concrete foundations of the old container. One leaves the landscape, sinking into the post-industrial Hades of the gas-tank foundation. A free-standing steel spiral staircase offers a way out, up towards the light of the occulus. Rising, one is immersed in the moving monumentality of the dome. The path eventually winds around the interior wall of the dome, past the planetarium and to the entrance door of the Galileum, which is cut into the shell. In the foyer, the sphere lightly penetrates the space, offering, through another cut in the shell, access to the planetarium. But an external stair tower offers more height, leading from the foyer to the observation platform. Here, one is with the stars.

The small Plot 2 features a compact, interconnected structure of communal cultural uses. Thus, the complex relationships of opening, demarcation, insight and separation give form to this urban building block. On Spielbudenplatz stands the small museum with a massive façade, crowned by a skate park. Its glass pedestal contains a café and a club, which extends into the basement. From here, a staircase connects the clubs concert space with the townhouse-style hostel next door.

The museum façade acts as a sound barrier, protecting the alley behind and the building itself from the noise of Spielbudenplatz. Operable windows are hidden in the trapezoids of the soundproof wall, and skylights are concealed in the volcanoes of the skate park. A bridge spans the alley, connecting the skate park to the adjacent 3D building of Plot 1. Here skaters spend the afternoon in the evening sun, enjoying the view over the Reeperbahn while a service entrance from the hostel supplies drinks.

The club has two function rooms: a day club on the level of Spielbudenplatz with a stage in the shop window and a subterranean club with a basilica-like layout under the alley. You descend into the club via a central staircase - with cloakroom and box office in what would be the organ loft. From the club, a service staircase leads up to the hostel, where visiting performers can lodge. The hostel is a narrow, eight-story townhouse on the alley with three small double rooms and a slightly larger private room on each floor. The rooms face the alley, each with a façade basket for airing clothes and storing travellers' belongings. A two-story restaurant, which also serves as the reception, opens onto the alley. Here, guests can spend their days and evenings before ascending to their rooms.

Ja, das möchste: Eine Villa im Grünen mit großer Terrasse,
vorn die Ostsee, hinten die Friedrichstraße;
mit schöner Aussicht, ländlich-mondän,
vom Badezimmer ist die Zugspitze zu sehn -
aber abends zum Kino hast Dus nicht weit.
(aus Theobald Tiger alias Kurt Tucholsky, Das Ideal, Berliner Illustrierte Zeitung 31.7.27)

To the north lies the urban street; to the south, a garden within nature. Here, one finds conditions out of Tucholski's "The Ideal."

The transition from the private to communal areas is finely graded, inviting contact between neighbors. To create a semi-public space along the facade, the ground floor moves back slightly. Each entrance hall is flanked by a finely tiled bench, helping the house to participate in the life of the sidewalk. The two-side oriented apartments have a continuous window strip towards the urban side, where a small balcony enables a connection, while a pergola creates balconies and loggias for all apartments along the garden side.

The building offers a variety of housing, from 2 to 5 ½ room apartments. These are distributed in a balanced mixture over all floors and provide for a wide range of living needs at various scales. The residents can use the floor plan flexibly; small spaces are arranged around a neutral distributor space, which can be both kitchen and living room. In the apartments from 2 ½ rooms or more, the user can decide freely about having a bedroom to the street or towards the garden. Some large apartments can be divided. Due to the flexibility of the ground plans, many alternative housing forms--such as cooperative housing, live/work housing or multi-generational living--are possible under one roof.

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.

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 Conversion of the Breisestraße Car Park – A model for Berlin

The conversion of a multi-story car park cautiously densifies the neighborhood with minimal capital, offering room for a community of 91 people. Construction costs of 828 € / m2 NF allow the tenant to pay a monthly rent of only 6.50 € / m2, ensuring equitable housing opportunities. The project is a model for Berlin; the Briesestraße Car Park serves as prototypical scheme, applicable to all d'Humpy system car parks.

All measures to improve the substance of the car park are carried out following the principle of least intervention. The removal of prefabricated ceiling elements enables light to flood in from above into private courtyards, allowing all flats to receive light from two sides. With minimal effort, the car park is thus transformed into a series of courtyard houses, each offering a range of apartment types formed within the ceiling panel grid.

A differentiated open walkway winds itself as a Rue Intérieure through the house with continuous natural light and visual connection to the outside world. Not only does this street provide bike, skateboard and scooter-friendly entry to the interior private courtyard houses, but it enables communal occupation, appropriation and adaptation through a series of common areas: guest rooms, workshops, kiosks, bike rooms, etc. After beginning near the multi-purpose hall on the ground floor, the Rue Intérieure, winds its way up the ramps through the building, culminating in the in the roof terrace, where residents can meet, play, relax and grill.

To occasion the 90th anniversary of the foundation of the Bauhaus, the Foundation of Weimar Classicism is organizing a large Bauhaus exhibition: 4 locations, 3400 m2, 1200 objects, one exhibition, one city: ‘Das Bauhaus kommt aus Weimar’ (The Bauhaus is from Weimar), April 1 - July 5, 2009. The exhibition architecture includes both the interior of the four museums - Bauhaus, Goethe, Schiller and Neues Museum - and connects the 4 exhibition locations to one another.

The inter-museum connection is made via so-called ‘text hedges.’ The text hedges—self-supporting constructions made of two 4 mm thick laser-cut steel sheets—feature quotations from Walter Gropius, which thematically introduce the exhibition. In front of the museums, the text hedges use existing flowerbeds, baroque balustrades and postmodern sandstone walls as substructures, adding a layer of exaggeration to Weimar's closed, harmonious urban space. The motif of the bourgeois quote—welcomed in Weimar—is, through human-sized lettering and radical content, brought to completion.  

The Bauhaus wanted nothing less than a new human: industrial mass production as the means to a glistening future... a future which has existed for more than 40 years now. The exhibition architecture is made of a single universal system, used in each museum. Made of aluminum square tubing and white Resoplan panels, this system is all-encompassing. It is made for the exhibition, the trade fair, the supermarket, the store fittings, the everyday life, the Gesamtkunstwerk, theater, photography, text, festivals, etc. The exhibition experience can then also be comprehensive: sleeping, eating, relaxing, looking, contemplating, watching film, seeing theater, teaching, arriving, leaving, returning…

Verzinkerpreis 2019, honorable mention: sustainability 

The staub&teer bike shop in Cologne is a sustainable project. The salesroom for gravel bikes and accessories of a Cologne bike factory had a fixed budget of €50,000 for 100 m² of space. For this, the complete drywall construction, the electrical, lighting and sanitary installations, painting work and the sales equipment were to be carried out. The shop - perfectly located in the Roman Cardo street - had no spatial or atmospheric qualities, so only a strong overhaul of the space would make the shop a place of commerce.

The spatial or atmospheric upgrading of the room is achieved by installing a construction system from an alien context - a ready-made. The galvanized EURO formwork construction system serves as a wall, room divider, paneling, door, counter and shelf, and can be deconstructed without leaving any residue. The differently joined modular elements, fixed by means of clamps, form a sequence of rooms: the vestibule, the counter space, the cabinet of curiosities and the bicycle gallery are lined up, one after another.

The construction system was built by the shop operators themselves in 5 days, and fulfills the individual functions through various modifications. Perforated or galvanized steel sheets are set with magnets; flush with the outside as a presentation surface or flush with the inside as shelf backing. As bicycle holders, bent anchor rods were inserted into the anchor nuts inherent in the system. As product holders, stock insert-able hooks were inserted into the perforated panels. The universal formwork, purchased for 30.000 €, required no modification, and can thus be resold after a possible dismantling.

Since opening, the bike shop has become a social meeting place—given its universality and the energy of the operators—serving this role in addition to that of a sales room: https://www.instagram.com/staubundteer/

The Neuländer Quarree is a decisive building block in the urban transformation of Harburg's inland port. While the typical port traffic, logistics and commercial structures will continue to exist in the long term, residential and leisure uses are beginning to move in, requiring protection—particularly from noise. The urban master plan successfully meets this challenge with the perimeter block development of the building sites, but requires careful architectural interpretation of site-specific qualities. Harburg's inland harbor possess an identity-forming heterogeneity; the autonomous juxtaposition of sometimes dramatically different spaces, scales and building typologies give the area a rough, disorderly charm. Yet disorder is by no means random. The individual buildings each have their own order—corresponding to their individual industrial processes—and they hold together, not through monotony, but through a shared vocabulary of infrastructural elements and a common landscape: large swaths of sky, inland waterways and the resulting presence of water fowl.

The Neuländer Quarree develops its qualities from this balance of autonomy and dependence. The unadorned romanticism of the harbor is reinforced through and engagement with found building types. To this end, conglomeration serves as a principle of orchestration, coordinating a concert of the ordinary, the bulky, the simple, and the magnificent. The individual structures of the quarter are united by the master plan in an orderly manner, and the small blocks create dwellings which deal with the challenges of alignment and noise. However, to participate in aesthetic qualities of their immediate surroundings, the blocks are opened up and re-interpreted as assemblages of smaller parts. These parts are understood as house types which take up an active relationship to their context, evoking memories of familiar residential buildings. The resulting collage is overwritten by a material similarity; the formal structure of corrugation applied in different materials: sheet metal, GRP, ceramics, and precast concrete. These elements are complemented by generous, fowl-safe glass, giving all flats views into the landscape.

The first conglomerate, A1, is composed of three apartment buildings around a small square, one symmetrical, one staggered, and one round. An elevated plinth containing a fully-glazed restaurant and multi-story bike garage connects the symmetrical building to the north with the staggered building to the south. The staged building, in turn, merges into the round building to the west, completing the three sides of the square. The second conglomerate, A2, is formed from a deep-row building and a villa, both sitting on a plinth. The plinth contains 5,6-meter-high studio or commercial units and a generous lobby, serving as address and communal space for the development. The final conglomerate, A4, is more composite, featuring a homogeneous inner courtyard formed by corner, terrace and apartment buildings. The inner courtyard is the garden of the day-care center, which is situated in a ring around it, while the corner and terrace apartments claim expansive views of the harbor.

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.

With the Mühlkanal quarter, Salach is developing a unique piece of the city and a special piece of the landscape. The space between the railway and the river Fils - both the infrastructural elements which have allowed the city to grow - is now itself joining that city. The industrial ensemble and the floodplain thus emerge as charged urban spaces. The 1,000 employees of the Schachenmayr, Mann & Cie company almost 100 years ago will now become approx. 1,000 people (approx. 700 residents, 300 jobs) who live and work in the Mühlkanal quarter.

The conversion and extension of the protected buildings establish an ensemble, both culturally and socially outstanding. The four buildings of industrial culture - each exemplary of the techniques, structure and design of its time - are carefully converted and minimally supplemented. These structures are only suitable for living in a few areas, and thus require a special programmatic mix, developed in relation to each structure. Each of the four buildings receives a loose focus: work/studio space, small-scale production shops, a market/event hall and culture/education. In the existing buildings, people continue to produce and work, but also research, trade, educate themselves, meet and relax. To create an urban fabric, however, more is needed; the generous areas for working are supplemented by diverse typologies for living.

The new buildings are added to the existing ones as new rooms in a spatial sequence; a continuation of the sites industrial logic. The saw tooth halls are connected to the factory building via the workshop, offering expandable residential studios of various sizes on two double floors and a building of cluster apartments. The long row of three wool-sorting buildings to the north is extended by one building. The resulting comb-like structure functions as mobility house for cars and bicycles, and features South-facing terraced apartments, forming the Northern edge of a lively residential street. The Southern edge is then created by three groups of back-to-back row houses. These row houses are arranged according to size, creating small plazas along the street to the north before condensing into residential paths leading southward into the landscape. Flanking these paths, small residential towers frame views toward the river. One step over the new mill canal and you are standing in the wild river landscape along the Fils. New gardens and meadows can be found here, seating steps can be discovered along the bank, and in the thicket of the otherwise inaccessible biotope, one finds the secluded refurbished Hattie-Barreis hut, now a picturesque beer garden.

The garden city estate of the Köln-Nippeser Bau- und Spargenossenschaft on Eisenachstrasse is one of the oldest cooperative housing estates in Cologne. Next to the large Nippes railroad repair works, the architect Heinrich Krings built around 60 inexpensive terraced houses for railroad workers' families between 1903 and 1905. The settlement won the gold medal for floor plan design at the 1900 World's Fair in Paris. As the last of the settlement houses to retain both street and garden-side facades, House number 38 is now listed for protection. The house suffered the misfortune of a lovelessly executed 90s renovation: three bathrooms were installed, rooms were divided, textured wallpaper and diagonally laid floor tiles covered the simple but robust original materials. By the time the new owners—a family with two children—purchased the house, this renovation had already worn out, but due to very high real estate prices, the remodeling budget was extremely limited.

For the new residents, the three separate units crammed into the existing building were re-integrated with selective interventions. The formerly semi-public stairwell was connected to the adjacent living and dining rooms, the kitchen was relocated to the street side, and the entrance hallway was demolished. A functional wall with integrated storage, work desk and through-way separates the kitchen from the newly created entrance hall. The dining room was given a door to the garden, and a fireplace area connects the dining room to the staircase. On the first floor, the demolition of the bathrooms made it possible to create space for a large living room adjacent to the children's rooms while the master bedroom with dressing room and a large family bathroom inhabit the second floor.

The entire house was remodeled with a dual strategy of brutalization and refinement. The new state is composed of the exposed fragments of all the previous ones: the visible shell of 1903, the framed extension of 1905, first improvements of the 50s, parts of the renovation of the 90s and contemporary interventions. All fragments are connected by a layer of beige paint, graduating their differences. The inset reading nook, fireplace bench, pass-through storage wall and shower niche, complete the programmatic expansion of the house. These new interventions follow the so-called ‘dental filling’ tactic: they fit seamlessly into existing conditions while revealing their independence materially.

BeL (*2000), Anne-Julchen Bernhardt (*1971) and Jörg Leeser (*1967): On Walter Pichler's Sketch for the Underground City, 1960-64, Model, 2019, metal, concrete, plaster, paint, foam, wood, pastel calk, wood glue, paper, coal, styrofoam, plastic, play dough, sandpaper and plasticine.

The selected drawing – a light-hearted but somewhat nervous sketch bearing the title “Sketch for the Underground City” – belongs to an early body of work by Walter Pichler.
Working on abstract, hypothetical cities and buildings, Pichler questions the relationship of oppositional systems and investigates into positive and negative space, the designed and the found object, movement in space and movement of space. He is fascinated with infrastructure, spatial networks and the architecture of transition.

Over the course of four years he produced several series of drawings and objects, as the first seem to be mostly investigative and only occasionally presentation drawings, the latter are artifacts of meticulous craftsmanship in metal, concrete and plaster. Resting in time as singular entities, they obtain an almost transcendental aura; their painstakingly precise and slow process of making is inscribed into their abstract yet detailed manifestation. Form, space, light, material and surface are taken into the realm of fetish objects, the Sublime hovers within and around them.

The enigmatic objects are called Compact Building, Underground Building, Mouth of an Underground City, Core of an Underground City, Building over Infrastructure and Underground Building with extendable core. There is no record of an object titled the Underground City, the selected drawing solemnly bears that name.

Our model is neither abstract nor enigmatic but concrete. It is a model not an object. Its simple stereometric volumes are directly taken from Pichler's sketch. As a feasibility study it explores possible levels of detail Pichler's sublime objects would have faced, if they had been taken as representative model in an architectural process. The model is in search of the inherent beauty of the ordinary, it emphatically embraces the everyday, where the Sublime is just around the corner. Still, the Underground City remains the Other Space, pink cavities crouch underneath the surface.

NEUBAU - on Königsberger Straße and Aleppoer Weg

Germany is an immigration country, in the metropolitan regions there is a housing shortage. By 2026 this shortage will amount to around four million affordable dwellings. In a large model NEUBAU shows four speculative self-build cities which represent a further development of the project Grundbau und Siedler that was implemented at the IBA in Hamburg. A comparison to the major reconstruction work after 1945 reveals similarities and differences over a period of ten years. We call the urban districts "city of assembly". They are co-productions; between the poles of self-determination and planning a wide variety of spaces is developed for community, production, trade, and private use. 50% of the residents have a migration background, these are districts for everyone.

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.

Following the example of the 1920s Haus Vaterland in Berlin, Plot 1 is an implosion of urban life that welcomes and delights residents of Hamburg and tourists alike. St. Pauli is formed by a variety of actors, a diverse cast of characters all of whom meet on the street. The hotel and 3D building stand on Spielbudenplatz, a colorful hybrid structure which becomes a street unto itself. It has two ground floors - one at ground level and one on the ‘Stadtbalkon’ - both with countless doors. These two floors—like the street they embrace—are dedicated to characters of St. Pauli, offering them new places for encounters, for meeting, and to linger. The balcony is a distinct throughway connected with the street by stairs at both ends: it is a street and a square in the air.

The hotel itself combines three different hotel types: the Grand hotel, the artist hotel, and the hotel tower. The foyer on the ground floor of the hotel forms a passage from Spielbudenplatz to the alley. Small retail / craft shops and a bakery are located here, enlivening this semi-public space. A double staircase leads upstairs to the lobby of the hotel, which connects the ground floor to the stadtbalkon. The façade facing Spielbudenplatz unites the different types into a multifaceted design that is reminiscent of the Esso houses as well as various famous hotels. The rooms are different in the three parts of the hotel. There is a room here for everyone.

Each hotel volume features a different public roof function. Crowning the lowest, western volume is Park Fiction 2.0: an open space for all Hamburgers. A stair leads from the park to the garden restaurant which inhabits the seventh floor of the tower and spills out onto the roof of the central hotel building; it offers a panoramic view over Spielbudenplatz, St. Pauli the roofs of Hamburg. The eastern façade of the tower provides the necessary elevation for a climbing wall, the faceted geometry of which gives the street face of the tower its distinctive form. The climbing wall is accessed from the roof of the adjoining 3D building.

The 3D building is a rectangular Leaning Tower of Pisa; a solitary building enclosed by columns and containing a winding vertical walkway. The tower extends the public space vertically. A freely accessible staircase begins in the alley, rising towards the city balcony to the East and then continues upwards towards the South in front of the hotel. From there you climb through a series of programmable public levels and overlook the alley from bridge to the skate park, before a final turn takes you up to the public climbing gym.

The Zollstock neighborhood in Cologne contains an array of different functions and building typologies. In the site’s immediate vicinity, there is a heterogeneous mixture of 3 to 4-storey perimeter block buildings, terraced buildings, free-standing 8 to 12-storey high-rise buildings, and 1-storey commercial buildings. The block interiors are often built up with scattered low buildings of 1-3 stories and connected to the neighborhood’s streets with doors and passageways.

Responding to a desire for both order and diversity, the scheme is modeled after the Pallenberg housing estate in Cologne-Weidenpesch. Built in 1906, the estate is composed of buildings around a central park and, according to the garden city principle, featured a community center with a reading room and public baths. A gatehouse flanked by other buildings gives access to the central zone.

The new interpretation in Zollstock consists of a 7-story, 16-meter-deep gatehouse on Bremsstraße and a smaller, 4-story, 12.5-meter-deep gatehouse on Heinrich-Brüning-Straße. In between, a 4-story building with a day-care center at ground level encloses the outdoor central common space. This central outdoor space serves as access for the flats and the day-care center, the play area and opens a new pedestrian crossing between the two streets. The inner building encircles the yard with a series of delicate arcades, providing access to the apartments and bringing life into the yard throughout the day. Between the inner building and the interior edge of the block, residents enjoy private gardens and balconies, while to the East, the daycare center opens onto a more protected play yard.
