📚Resource overview: “Open Access Journal Towards a “Freiburg Model” of Housing for the Common Good? Fostering Collaborative Housing in Urban Development” is a peer‑reviewed article in Urban Planning (Volume 9, Article 8191). It is authored by Benedikt Schmid (University of Freiburg), Carola Fricke (Saarland University), and Cathrin Zengerling (University of Freiburg), and examines the district development project “Kleineschholz” in Freiburg, Germany, as a case of collaborative housing and municipal steering towards the common good.
🌍Why this matters for sustainable housing: The article situates Kleineschholz in wider European debates about the social and ecological costs of capital-driven housing markets and the search for a “third way” beyond market and state. It uses “collaborative housing” as an umbrella term for initiatives prioritising goals other than profit (including co-housing, resident cooperatives, and collective self-organised housing), and emphasises that “common good” (Gemeinwohl) orientations do not always align with formal charitable/non-profit status (Gemeinnützigkeit).
🏘️Case study basics (Kleineschholz, Freiburg): Kleineschholz is planned in Freiburg’s central Stühlinger district, with around 500 residential units on a 77,500 m² site. The planning process began with citizen dialogue in 2010 and has included multiple participation formats. The project is promoted as 100% oriented towards the common good, aiming for affordability, sustainability, tenant protection, and long-term retention of properties.
🧩How the municipality steers outcomes: The core lever analysed is concept-based tendering (Konzeptverfahren) for allocating publicly influenced plots. Rather than a rigid point system, Freiburg designed a more qualitative, “open” evaluation intended to support innovation and neighbourhood diversity. The tender design is complemented by planning instruments and contracts (land-use plan, leasehold or purchase agreements, repurchase rights, and tenant-protection commitments) to legally anchor common-good standards.
🤝Actors, eligibility, and safeguards: The tender targets actors oriented towards the common good and excludes individual ownership models such as building groups with private unit ownership. Eligible applicants include (1) organisations with tenant participation in asset value (e.g., cooperatives or Mietshäuser Syndikat-type structures), (2) entities with a public/municipal/church mandate for services of general interest, (3) entities promoting social/ecological/cultural aims (with reference projects), and (4) employers’ housing for essential professions. Safeguards described include no conversion into partial ownership, obligations to retain buildings for at least 30 years, restrictions on resale, and tenant protections such as no termination for personal use and limits on luxury refurbishments.
📈Financing, costs, and implementation challenges: The article identifies financing as the main risk for collaborative housing groups, especially amid high construction costs and interest rates. It reports financial support measures including a time-limited grant from the former landowner (BImA) of over €6 million for subsidised housing construction and a municipal subsidy of over €6 million to reduce privately financed rents in the medium term. It also notes that Freiburg adjusted the original leasehold-only approach by reintroducing purchase options (with a repurchase option after 99 years) due to subsidy-program constraints.
🌱Sustainability measures and debated constraints: Kleineschholz includes a centralised energy concept with district heating (contract concluded in December 2022), compulsory connection to the grid, photovoltaic requirements (35% of building floor area specified as PV module area), and a minimum “efficiency house 55” standard. Collaborative housing groups interviewed welcomed the ambition but criticised some early decisions and detailed regulations (e.g., energy concept choices and prescriptive planning rules) as limiting flexibility for alternative solutions.
🔎Key conclusions and transferability: The authors argue Kleineschholz represents an experimental “lighthouse” project enabled by public land control, sustained municipal capacity, and long-term relationships with an established collaborative housing ecosystem. At the same time, they caution that transferability is constrained by the precondition of public land ownership and the high time, personnel, and financial investments required. Kleineschholz is presented as offering practical lessons for municipalities seeking socio-ecological housing transformations, while also highlighting the limits of project-based solutions in addressing broader distributional conflicts around living space.
