Overview of the Initiative
The article, published by the Stuttgart‑based magazine Magazin QUARTIER, examines how citizen pressure transformed land allocation in Stuttgart’s Olga‑Areal from speculative auctions to a fixed‑price model based on market value. The piece details the development process, challenges, and outcomes of the urban renewal, highlighting the role of resident‑led building communities (Baugemeinschaften) in promoting affordable and sustainable housing.
Development Process and Timeline
Stuttgart’s city planning office introduced the “Bürger bauen mit – Baugemeinschaften in Stuttgart” proposal to the council in 2012. Since 2014, building groups have been required to pay only the Verkehrswert (market value) for plots, yet many still find these prices prohibitive. A 12‑year delay in the project’s execution was deemed unacceptable by residents, who called for stronger political oversight and cost‑conscious planning. Major milestones include the 2014 relocation of the hospital, the demolition of the old clinic, and the removal of a 1.5 m thick, 1,000 m² concrete slab under the high‑rise, which required controlled blasting and deep foundation work.
Coordination and Community Involvement
The city’s project management coordinated four construction fields but lacked a dedicated on‑site coordinator, leading to fragmented communication. When a contractor withdrew from the underground garage work, the building groups’ leaders convened to re‑organise the effort. Each new dwelling includes a dedicated parking space, and units larger than 35 m² also receive a bicycle parking spot; the Olga07 site, for example, accommodates over 40 bicycles in a communal bike cellar.
Social Mixing and Affordable Units
Three programmes support social mixing within the redevelopment. In the social rental sector, 54 apartments were built at 33 % below the local market rent, while 31 medium‑income rentals were offered at roughly 20 % below market rates. Additionally, 32 affordable ownership units were created, resulting in a total of 117 subsidised homes. A developer later pledged to relocate 14 of these units elsewhere as replacement social rentals.
Innovative Building Communities
Early occupation of the Olga07 site demonstrated that Baugemeinschaften can operate as efficiently as conventional developers. The article cites plans to extend this model to include cooperatives and socially‑oriented private developers. Notable projects include the “MaxAcht” timber construction, recognised by the Baden‑Württemberg Architects’ Chamber for exemplary building, and the “Olga07” development by Manderscheid Architects, both exemplifying environmentally conscious design.
Shared Spaces and Community Benefits
All building groups feature a communal room used variably as a sound‑proof rehearsal space, a recording studio, or a neighbourhood hub. When the local Stadtteil‑ und Familienzentrum (SFZ) was initially undersized, the Olga07 community offered its shared space to the centre, reinforcing neighbourhood cohesion.
Key Figures at a Glance
- Total subsidised units: 117
- Social rental discount: 33 % (54 units) and ~20 % (31 units)
- Affordable ownership units: 32
- Bicycle parking provision: ≥1 spot per 35 m², >40 spots at Olga07
- Concrete slab removed: 1.5 m thick, 1,000 m² area The article demonstrates how citizen activism, combined with fixed‑price land allocation and cooperative building models, can advance sustainable, affordable housing in urban German contexts, offering a potential blueprint for pan‑European cities facing similar housing challenges.
