After the purchase of a small settler’s house from the 1950s, there was not much money left for a young family to build themselves a home. The decision was therefore made to refurbish and extend the existing house rather than rebuild it, saving not only money but also the material and energy conserved in the existing structure. The settler’s house is treated as raw structure into which the new is fitted, tuning up the typology, energy use, and accessibility of the house.

The suburban house—its spatial qualities having blurred, its references to history and context gone dim—is brought back to its origins and transformed into architecture. The three stories of the house are differentiated and formed through three different spatial concepts: A lengthwise directed living space on the ground floor, separate rooms circulating around a central access area on the first floor, and an open space concept in the attic.

The load-bearing walls are retained, while the different spatial concepts are introduced into the structure. The new lengthwise directed rooms on the ground floor connect front yard and garden, through the living space. Spacious double doors in the cross-direction link the new terraces on the sides of the house to both living room and kitchen. The new staircase is relocated on the outside of the house, connecting ground and first floor without disrupting the open character of the living-space. The four rooms of the first floor become individual characters—morning, day, evening and the north/garden room—through single windows, all facing a different direction. The attic bares the possibility of being buildout into an open space bedroom, arranged around a well-positioned bath box.

The small house stays small. It grows in length by 2.20m and in space from 118 to 152 m². The extension rests on the foundations of the former terraces and is built in a light steel construction fitted with wooden walls. The new, insulated rafter-roof connects both parts of the house. The outside walls of the existing structure are insulated and plastered. While the different constructions and materials differentiate the new and the old are inside and out, the overall coloring of the walls keeps this effect subtle.

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.

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.

Grundbau und Siedler explores how lower income groups can become home owners. This project was originally developed in the framework of the IBA Hamburg 2013 for the urban district of Wilhelmsburg. The dominant typology in this area is the allotment garden hut, in the 1970s large social housing complexes were also erected there. Although the theme of these developments was "urbanity through density", they are neither densely built nor do they succeed in producing any sense of urbanity.

The project by BeL stretches the typology of the hut to multi-storey housing – a skeleton provides the basic frame, its different stories can be individually filled out, both spatially and over a period of time, by the residents themselves employing self-build methods. The future home-owners buy a package consisting of a plot within a basic, concrete-built skeleton, all the building materials needed to develop their plot, and a handbook giving detailed instructions on all the steps necessary for the development work.

In warmer climatic zones Le Corbusier's Domino House principle from 1914 has proved its value as a successful construction system for informal housing developments. Aashwa´i in Cairo, Polykatoikia in Athens, Gececondu in Istanbul, and Favela in Sao Paulo confirm the superiority of the Domino construction principle – and not just from the viewpoint of costs. It is a shelf that provides ideal conditions for a mix of functions; a surplus of space creates a flexible basis to be appropriated by future extensions, conversions and adaptations. The open basic structure allows flexibility over a long period of time.

Applying the Domino principle in Germany today requires specialized materials and details in order to satisfy the demands made by highly developed post-industrial societies regarding comfort, economy and ecology. The Grundbau or skeleton has a single staircase serving three units on each floor, the structure is five-storeys high and offers twelve sites for settlers. Each of the upper four stories has three units, whereas the ground floor contains the settlers' private workshops, car parking spaces, the public utilities connection room and the approach to the open staircase.

The settlers acquire a complete kit of building components to erect a typical settler's house. This kit contains all the construction material. A detailed handbook describes the steps that they can carry out themselves, as well as indicating those areas of work that must be approved by a specialist. The organization of the floor plans is independent of the load-bearing structure and the neighboring stories. All versions of the typical floor plan in the settlers' kit address different housing needs (the number of persons, lifestyle etc.) and changes of function over time (a growing family, the advent of old age, change of user). A set of functionally neutral spaces is offered with an abundant number of doors. Consequently, the users can employ whatever function they wish. All the rooms are connected to each other; each room has openings to its neighbors. The large number of doors allows the rooms to be grouped as required. For instance: one family may want a large bathroom with a view, whereas another may use this room as a child's bedroom. Each dwelling has two service shafts that are positioned at the intersection of the partition walls and can serve three rooms.

The settlers decide what the rooms will be used for. Flexibility results from use and not through adaptation. Functionally indeterminate spaces in a floor plan without corridors require the settlers to interpret and conquer their own space. In the 1:50 scale configuration model (contained in the building kit) the settlers can examine which ways of using the spaces work best for them. Those who wish so can ignore the recommendations and the material offered in the building kit and can improvise. Settlers can reject the guidelines within their own plot, everyone has the right to make their own mistakes and improvements. The Grundbau contains everything needed to build and operate a unit; the settlers can use the workshop spaces on the ground floor from day one and can run their own construction site from there. The Grundbau has railings making scaffolding unnecessary, the settlers can carry out their work from the 70-cm wide strip of balcony.

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.

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.

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

Diagrammatically formulated, this solitaire bundles the entire interior program along Mercedes Street and raises it, thus obtaining a coherent, permeable green space which connects all adjacent streets. This minimizes pavement and maximizes potential areas for vegetation and social interaction. The building is a 38.5m high and 25.4m deep, functional hybrid. It is set back towards Mercedesstraße, tangent to the property line at Gartenstraße and at Poststraße it keeps maximum distance to the opposite development; a respectful neighbour. As a high point, the building is clearly perceptible from every side due to its precise positioning, without triggering conflicts with the buildings opposite. On the contrary, it creates new urban contexts and gives expression to its public purpose.
 
The entire area lies at the center of a "shared space" formed by the surrounding streets of Mercedesstrasse/Gartenstrasse/Unter Torgasse and Poststrasse. The boundaries of this urban space are fluid, pedestrians and cyclists enjoy absolute priority, and the speed of all vehicles is reduced to a minimum.
 
The 5.8m high first floor of the 11-storey structure has a special significance. Its structural footprint is minimal and its height maximal to allow permeability in all directions. Each side forms special subspaces; the quiet entrance hall of the apartments is located on Poststrasse, while the more public Mercedesstraße is lined by a colonnade with accompanying trees. Here, tables of the café of the Kultur- und Bürger*innenzentrum can be placed in the morning sun. This space leads southwards into the urban loggia, where a cantilever created by the sloped seating of the civic hall above forms a public, covered outdoor space. In addition to its function as the entrance area of the cultural and civic centre, this space doubles as a lively forum for cultural and social activities at the intersection of Mercedesstrasse and Gartenstrasse. To the West, between the building and Unterer Torgasse, the public green space provides shade, calm and room to relax.

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/

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 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 qualities of life in the ‚Horner Geest‘ are strengthened and further developed - from mono to multi: We identify minimally different settlement clusters in the existing urban fabric and develop them into character-rich neighborhoods. The aim is to be both more diverse and more specific.

The green character remains: different open space potentials are adopted, strengthened, interlocked with the neighborhoods and connected to a coherent space - the Green Loop. It is full of program and establishes a new hierarchy within the district; all 19 clusters lie along it. A bike path connects all public open spaces.

The narrative street links the neighborhood: Manshardtstrasse becomes an experiential space between green and urban where exchange, commerce and trade take place. Three centers form on this diverse artery, in between the neighborhoods present their unique faces to the street.

A lively piece of the city is created: diverse building typologies and open spaces, clear hierarchies and spatial sequences, individual identities and neighborhoods - connected by the Green Loop - continue to write existing spaces and the identity of the place in a contemporary and future-oriented way. The result is a mixed district in which everyone is welcome to live, work, learn and play.

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.

The Ribbon is the center of the co-living campus, where all paths, encounters, entrances and pauses come together. It is generously permeable, greened, shaded by many trees and interspersed with sports and leisure areas.

4 Living in courtyard communities
At the Ribbon, two courtyard communities are developed from the existing buildings, one is added to the east, and the spontaneous woodland encampment is left in place. With between 30 and 200 residential units apiece, each community is centered around a unique relationship to open space: a central communal courtyard garden, a private garden/communal alleyway, and a view into the surrounding landscape.

5 Studying and researching in society
A compact, divided infrastructure results in three clusters of larger building plots for the university. One half of each of these clusters is located on the Ribbon and uses and promotes its public nature. Studying, researching and working takes place in society.

This project is structured around climate protection. It translates parameters of climate-friendly building into form. The structure is determined by fresh air movements, the drainage patterns and a regiment of minimal paving of the former agricultural landscape. The entire development is placed as a coherent figure in the landscape, against which it communicates and responds.

The movement and open spaces represent air corridors, the cool air from the fields is passed on into the area. The green main structure of a boulevard, formed by straight lines and circle segments, forms a first order, from which green landscape pockets depart. The main structure oscillates along the existing landscape elements the adjacent cemetery and fields. This structure also translates fire regulation into the form of the urban design in order to minimize paving. Thus, our paved circulation requires only 6% of the developments area instead of the planned 15%. This saved 9% is dedicated to green spaces. On the boulevard there are buildings that open outwards. The structures are higher along the boulevard and lower towards the landscape, framing vistas. Towards the South, the structures are composed by conglomerating housing typologies.

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 freight station in the Düsseldorf district of Derendorf has not been in its original use for several years, but has been occupied by a variety of temporary, alternative uses. This process of conversion will be completed in early 2005 with the demolition of all existing structures and the construction of new buildings for living and working.

Among the existing structures, at the site entrance, is a truck scale consisting of a concrete area for trucks inlaid at ground level and a small building for the scale apparatus. This building will be used by Orte e.V. as an exhibition and event venue for one summer. On 25.6. 2004, the 105th birthday of architect Hans Schwippert, BeL opened the exhibition entitled "Walden".

"Walden, or Life in the Woods" is the most famous work by Henry David Thoreau. As an account of his experiences, it describes the years from 1845 to 1847, during which Thoreau, a teacher and surveyor, built a log cabin not far from his hometown of Concord, Massachusetts, on Walden Lake and lived there as a hermit.

The truck scale belonged to the Swiss shipping company Danzas. After Louis Danzas fought for Napoleon at Waterloo, he began working for the Michel l'Eveque transportation company in St.-Louis in 1815. He became a partner in 1840 and lent the company his name soon after.

"Walden" includes three makeshift furniture made of poplar plywood and staples. All dimensions of the furniture comply with the DIN formats of the German Institute for Standardization. A couch, a chair and a table make the building habitable.

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 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 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.

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.

The new harbor square will be a lively, public space for city of Mülheim in the future. With its northern end, the bike station adopts the building line of the  adjacent residential buildings, forming the southern end of  the ‘Hafenplatz,’ the harbor square. The bike station is not a piece of street furniture, but a small public building. It is modeled on the urban loggias of the Italian Renaissance and the neoclassical drinking halls of 19th century Badish architecture. As a new building block in the urban fabric, the bike station establishes a connection with the larger public buildings on the banks of the Ruhr. The public bath, public hall and the city hall shape the character of Mülheim, their limestone facades and arcades defining a measured, dignified urbanity. The bike station continues these arcade spaces, a new interpretation of Hafenplatz.

The building is vertically divided into two zones. The ground floor houses the kiosk, bicycle parking and the transformer station. The transformer is clad in simple white steal, doubling as urban furniture. 34 bicycle parking spaces are created by the columns in the fully covered area, with twelve additional parking spaces possible along the edges. The walk-in kiosk has a sliding glass façade and mobile furniture, allowing for a variety of configurations. When the glass facade is open, a space without thresholds is created, the boundaries between public space, bicycle parking and the kiosk's lounge zone dissolve. The occupation of the loggia with multiple functions creates a covered public space which becomes an active part of the city through informal use.

The attic zone of the building has several functions. In urban space, it creates the necessary presence of a small public building, giving the eaves a height of 5.1 meters. The trusses form a light coffered ceiling, framing lamps and bringing a soft, diffuse carpet of light to the square in the evenings. The exterior facades of the attic offer a canvas for the artistic examination of the city. In a separate call for tenders, an artistic work in the tradition of the frieze can be commissioned here.

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.

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.

Ja, das möchste: Eine Villa im Grünen mit großer Terrasse,
vorn die Ostsee, hinten die Friedrichstraße;

vom Badezimmer ist die Zugspitze zu sehn -

(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 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 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.

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.

After years of consolidation on the inner edge of Hamburg's periphery, 16,000 new neighbors are expected in Bergedorf-West. This densified, new charged Bergedorf is investigated through parameters given by the existing urban-suburban structure.

The existing indifferent spaces will be transformed into new urban spaces, each of which will exaggerate its specific qualities and connect to the others via a network of well-defined open spaces. The aim is to be both more differentiated and grander than before.

Four spatial figures reinforce the latent spatial configuration by means of new construction: These juxtapose spatial typologies from the city, suburbs and village. The space is not drowned in newness. Types are read from the existing spaces and inscribed more definitely, volumetrically. Each new word giving a fresh meaning to its context. Life in Bergedorf becomes at once more urban and more scenic.

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.

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.

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.

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.
