Arbejdernes Byggeforening (lit. "The Workers' Building Society") was a Danish building society founded in Copenhagen in 1865 to provide healthy homes for the city's workers, especially those from the Burmeister & Wain factory. At the time of its foundation, the society had just 200 members but it grew fast, reaching 16,000 in 1890, and peaking at 26,342 members in 1955. The society built a total of almost 1,500 terraced houses at various sites around the city, including in Østerbro and Humleby in Vesterbro, before it was dissolved in 1972.
