The Wohnungsbaugenossenschaft Berolina is a housing cooperative that has shaped Berlin's residential landscape for nearly seven decades. Founded in 1956 as the workers' housing cooperative "Junge Garde" at a fire station in Littenbach Street in Berlin-Mitte, the organization built its first residential building in Adlershof just one year later.
Today, the cooperative manages approximately 4,000 apartments across several Berlin districts, including Mitte, Lichtenberg, Pankow, and Treptow-Köpenick, serving around 5,000 members. The majority of its housing stock was constructed between 1956 and 1989, with comprehensive modernization carried out from the 1990s through 2016. Notably, Berolina operates the largest cooperative housing quarter in central Berlin, with roughly 3,000 apartments in the Mitte district alone.
Since 2000, the cooperative has systematically expanded through new construction projects, adding 353 apartments to its portfolio, with an additional 17 units currently under construction and scheduled for completion in 2025. The developments emphasize accessibility features, spacious balconies, and extensive green spaces.
Beyond housing management, Berolina maintains two community centers—"Jakob" in Mitte and "Frieda" in Adlershof—where members operate libraries and participate in various activities ranging from sports to literature circles. The cooperative also provides social counseling services through partnerships with social service providers, offering members confidential and free support.
Berolina prioritizes sustainability in its operations, focusing on energy conservation, renewable electricity, and carbon footprint reduction as integral components of its long-term property management strategy.
