The Berliner Bau- und Wohnungsgenossenschaft von 1892 eG stands as one of Berlin's oldest housing cooperatives, founded on March 9, 1892, as the Berliner Spar- und Bauverein. During a period when rural workers flooded into Berlin and rents had surged 75 percent between 1880 and 1892, the cooperative emerged from an initiative by wealthy citizens who sought to provide better living conditions for workers through collective ownership.
Today, the cooperative manages approximately 6,900 apartments across various Berlin districts and serves over 18,500 members. As co-owners, members gain protection against arbitrary rent increases and apartment sales, with surplus profits reinvested into property maintenance or returned as dividends.
The organization's portfolio includes significant architectural heritage. Two UNESCO World Heritage sites belong to the cooperative: the Gartenstadt Falkenberg, known as the "Tuschkastensiedlung," built between 1913 and 1916, and the Siedlung Schillerpark, both designed by Bruno Taut. The Wohnanlage Proskauer Straße, constructed from 1896 to 1898 by Alfred Messel, won a gold medal at the 1900 Paris World Exhibition.
Recent construction projects demonstrate the cooperative's focus on sustainable densification without additional land consumption. At Ortolanweg, 26 new apartments were added through a two-story wooden hybrid construction atop existing buildings. The Nettelbeckplatz renovation transformed a 1970s estate by adding 40 apartments while incorporating energy-saving measures, accessible housing, and communal spaces including student apartments and senior living arrangements. The cooperative operates concierge offices in Charlottenburg, Spandau, Tempelhof, and Wedding, providing members with practical assistance ranging from shopping to interpreting official correspondence.
