In recent years, there has been much discussion about the expanding role of architects in the making of cities. While this has often skewed idealistic who really wants an untrained transportation planner designing aesthetically pleasing but semi-functional subway lines? in certain cases, architects have led the vanguard of alternatives to development-as-usual. This is very clear in Germany, where new models for housing have emerged, ones that take ideas about communal living out of the realm of hippie collectives or alt-squats and into the pragmatic territory of pooled finances and homeownership. The Baugruppen German for building groups is one model for constructing housing in this future of architect-led, collectively funded communitybased living. Berlin has become a prime site for alternative everything, and the R50 Baugruppen project embodies a fantastic wish for cohousing to ease some of the problems of the housing market.

Wurster, a journalist and translator, and Fezer, who also owns Pro qm bookstore renowned in Berlin for its selection of art, design, and architecture books built a custom unit to divide the central living space. Opposite: Many surfaces are as they were upon move-in, with the cinder block wall dividing their unit from their neighbors, visible in the dining area. Fezer fashioned the feature wall from old Ikea furniture, construction wood cut to various lengths, and other reused elements. It incorporates kitchen storage, a bar, and a piano nook (end page). 158
Named for its location at Ritterstrasse 50 in Berlin s Kreuzberg neighborhood, R50 stands seven stories, surrounded by green and blocks of typical social housing. Nineteen households built the building together, the modern way: Funds were pooled for construction and the purchase of the plot, and participatory planning catalyzed a comprehensive vision, from communal space to window fittings. The group and its architects, a collaboration between ifau with Jesko Fezer and Heide & von Beckerath, selected the site from a set offered by the Berlin Senate Department for Urban Development part of a city government bid to spark development outside the usual mode of initial investment for maximal short-term profit. The developer-driven side of things has left a bad taste in the mouths of many, as the center of Berlin faces a crisis of affordable housing, similar to the situation in Munich or Hamburg. Along with rising rents, there s evidence of a high-end condo rush, with properties like Fellini Residences or one2one driven by local and global developers, snapped up by eager empty nesters and suave speculators alike. Even with these new buildings, the business institute IW Köln estimates an overall deficit of 10,000 housing units in Berlin year to year until 2030. A remarkably low 43 percent of the housing in Germany is owner occupied, as estimated in the most recent national census in 2011. Rents have increased just as the country s storied tenants rights have slipped in the face of asset leverage through property-based profit. Where unlimited leases with difficultto-raise rents were once the norm, now there is national political discussion of mietpreisbremse, a brake on rental prices. The shortage of housing stock in Germany s urban centers, lack of newly constructed public housing, and the sale of existing public housing to private controllers have all heightened anxieties. The time for alternatives is now. The Baugruppen is a solution for the moment, when the city is not acting as it should, says R50 resident and artist Florian Zeyfang. For R50, the architects gathered potential residents from their networks, including friends, acquaintances, and collaborators. The group assembled includes architects, artists, and journalists professions that don t net the typical buyers or MAY 2015 159
A folding, multiple section wall not uncommon in Germany allows the unit to be opened to the outside, permitting fresh air and access to the balconies that wrap the entire building without separation between units. The balconies are made from galvanizedsteel panels, harmonizing with the mesh on the balcony rail, which is used as a standard fencing material in Germany, sold in rolls. Opposite: Wurster and Fezer s bedroom, pictured in the foreground, is triangular and can be opened up to the house or closed off. Two children s bedrooms and a workroom line the shared corridor along the facade. 160

The simple, standardized construction principles of R50 are evident in Wurster and Fezer s unit, with walls of plywood, a sealed concrete floor, and the prefabricated elements. A custom-built bookcase (left) is the striking exception. The vintage furniture, lovingly restored and reupholstered (right), is sourced from northern Europe, and includes coffee tables made by Fezer from patterned laminate panels designed by Ettore Sottsass. While the more communal aspects of R50 might smack of 1970s California communes, its rational, financial, and functional planning places it firmly in another, less idealistic category. builders of new homes. They all essentially bought into the project, with everyone purchasing his or her unit in the building on spec before it had even been developed. The bank and project manager structured a package of financing by pooling the individual mortgages for the units of future residents that would fund all the phases of construction. This unusual method of financing was made possible by specialized programs offered by Nürnberg s UmweltBank, the self-styled greenest bank in the economic ecology of Europe s financial leader. The invisible hands of the market can strum a sitar, if need be. Yet the thing that elevates R50 beyond just a clever financing model is that it was designed with the intensive participation of its residents. The architects facilitated the process, starting with the founding of the building group, leading participatory planning and design meetings. We knew why these people, why this building, explains architect Verena von Beckerath, who, along with the project team, prepared diagrams to reproduce the results of the meetings and quantify individual spatial needs and input into the shared spaces. The collaborative method was also logical, as each unit s mortgage had to also carry a share of any collective areas. Per square meter, the apartments in R50 cost 2150, and, with public space costs factored in, 2350. The median purchase price for simply buying an apartment in Kreuzberg was 2950/square meter in 2013, according to data from commercial real estate company CBRE. R50 is a comparative bargain. The apartments are divvied up in size by investment and in structure by the preferences of each resident with an agreed basic standard for all building elements. While private developers offer an appealing facsimile of bespoke choice 12 bathroom tile colors! Wood or marble countertops? R50 began from desire and negotiation. The modest price meant that the units were delivered finished, but not entirely done, says resident Jesko Fezer, who was also a member of the team of architects who led R50 s construction. A project is not finished when the architects leave typically, they start and finish in a certain period in the life of a building. In the case of R50, this was a self-conscious decision to leave things flexible for adaptation, especially evident in Fezer s own unit. 162
The architects developed a concrete shell structure with modular wooden elements and a wire mesh facade to accommodate the variations of internal layout the studies called for. The residents opted to make the ground floor a shared space sensible given restrictions on locating apartments in the neighborhood that includes a double-height community room and laundry facility. A rooftop summer kitchen and deck is an outdoor gathering space for Berlin s northern European late-light nights, and wraparound balconies are a shared outdoor space and secondary exterior circulation route between apartments. Popping over to a neighbor s for a coffee, stepping around terra cotta flowerpots and scattered toys, becomes more intimate than crossing a hallway, as you pass your neighbor s bedroom windows. Yet this idyll is exactly the most fragile point of the Baugruppen. The communal aspect hangs perpetually in the balance with individual ownership. While the original residents might uphold the underlying tenets of the groupthink project, the question of selling and selling out comes up. Under German law, owners of units in the R50 building and other similar cohousing complexes can sell to whom they please. This, naturally, leads to some anxiety on the part of the community of owners, which only time will put to rest or realize in new, nasty neighbors. The architect-led revolutionto-be in housing is not perfect, though, at the very least, it certainly promises something different. Most importantly, it scales beyond a boutique project ifau and Heide & von Beckerath are currently developing a mixed-use Berlin Baugruppen complex with nearly 100 units. As that project demonstrates, the Baugruppen model represents an innovative strategy for constructing new housing. Baugenossenschaft (co-ops) and Baugemeinschaft, a form of cohousing led by an independent consultant-as-developer, often with an architectural background, have emerged as viable options as more Germans look to become homeowners. While the structural dimensions of the housing market are beyond the control of any building group, the fact remains that the growth of different ways of making buildings beyond typical public or private development is increasingly popular.

Scaling Up CoHOusing Alternative housing strategies have surfaced as more Germans aim to become homeowners. Landscape and urban planner Ulf Maaßen leads AREA, a consultancy for Baugemeinschaft projects in Berlin that, similar to R50, often serves those who could never otherwise afford their own homes let alone ones they had a say in designing. His approach is hands-on: If someone comes obviously intending to use the apartment for profit and not for living, I wouldn t recommend that person for inclusion in the building group. There are advantages to this level of control at the larger scale. At Eschengraben 10 14 in Berlin s dense Pankow district, a group of seven buildings, most built with AREA s management, share an enormous common yard. This is the extension of an idea of common space shared by a single building to encompass a block of cohousing. It s an excellent case study for a city with many central courtyards too often sadly separated by fences over plotlines. 164
The stairwell of R50 has become an important social space for meeting and greeting, and often for the games of the resident children in the building, for whom it becomes an extension of family space ripe for imagination. For Fezer, the staircase is one of the most important social areas in a building, one that is often overlooked or under-utilized, but in R50, this service core has been reclaimed. The architect-led revolution-to-be in housing is not perfect, though, at the very least, it certainly promises something different. Most importantly, it scales beyond a boutique project. The socioeconomic dimension of this is interesting to Fezer, who cofounded one of the leading architecture and design bookshops in the city, Pro qm, home to many a debate about the state of architecture. We have to think about the role of the architect if we have a social idea of how the profession can contribute to society, he says. When architects like Fezer can work to counteract investment-driven development, that is a clear positive form of engagement. The Baugruppen concept holds the promise of applicability outside of Germany. In the U.S., where 65 percent of residents own their dwellings, the swelling of the housing market s boom, bust, and residual bruising has left many in search of new ways to acquire a home insulated from or in avoidance of the predatory developerlender complex. A 2015 report by the Brookings Institution detailed a growing gap in proximity between low-income people and employment centers in America; both have suburbanized, but concentrated in different places, while in metropolitan centers, rent and home-sale prices have steadily increased, squeezing out both low- and middle-income sectors. While the more communal aspects of a project like R50 might smack of 1970s California communes, the building s rational, financial, and functional planning places it firmly in another, less idealistic, category. Don t call it a commune. It is undeniable that architects and planners can be active facilitators and mediators of the built environment, aiding in its development and offering alternatives to the norm. Just as food trucks opened up the restaurant business to those excluded by high barriers to entry in the form of starting and operating capital, perhaps the Baugruppen idea of cohousing offers a way for more people to act as developers, cooperatively creating buildings and communities. Surely, it could be the initiative of architects to begin these processes, exercising their agency as designers, expanding their professional role. M MAY 2015 165
The double-height shared space on R50 s ground floor is legally considered a winter garden, allowing the full-wall doubleglazed panels. This common area houses a baby grand piano, eclectic furniture, and ping-pong and foosball tables, along with a gallery-level guest room available for use by visitors to R50 s owners. The space was designed to be flexible enough to allow a later transformation into two levels, in anticipation of changes in the needs or desires of residents. 166
