STATTBAU HAMBURG

What STATTBAU HAMBURG does

STATTBAU HAMBURG GmbH is a Hamburg-based project development and Baubetreuung (construction supervision) firm founded in 1985 by MhM (Mieter helfen Mietern), the Autonome Jugendwerkstätten, and Netzwerk Selbsthilfe to enable self-managed and alternative housing forms. The company serves two primary client groups: (1) social organizations — facilities, foundations, carriers, and institutions that build or renovate housing for public welfare purposes in Hamburg, and (2) Baugemeinschaften (building communities) — groups of individuals planning joint residential projects. Core services span project conception through completion, including architectural planning, energy consulting, financing coordination, and construction management. The firm also operates a publishing initiative, FREIHAUS (since 1997), an annual magazine and online archive covering communal and self-determined living topics, and hosts the Wohnprojekte-Tage, an annual networking event for housing projects.

The business model combines fee-based project development and construction supervision services for housing cooperatives, social organizations, and Baugemeinschaften with municipal subsidies from the Free and Hanseatic City of Hamburg — under a formal contract since 1997 covering 'Stadterneuerung und soziale Arbeit' (urban renewal and social work) — which fund the free initial consultation, the Wohnprojekte-Tage event, and the FREIHAUS publication. Geographic reach is primarily the Hamburg metropolitan area with selected projects extending into Schleswig-Holstein (Wedel, Itzehoe, Ahrensburg, Husum) and Lübeck. A wholly-owned non-profit subsidiary, STATTBAU HAMBURG Gemeinwohl gGmbH, was established in 2025 to pursue common-good-oriented housing projects serving people with disabilities, the elderly, families, and LGBTQ+ individuals. The firm maintains long-standing partnerships with multiple Hamburg housing cooperatives (Schanze eG, Langenfelde eG, Wohnreform eG, Brachvogelweg eG) and co-founded both P 99 Gebäude-Verwaltungsgesellschaft (a service company managing ~500 residential and commercial units) and the Wohnreform eG umbrella cooperative.
