Arbejdernes Byggeforening

The society built a total of almost 1,500 terraced houses at various sites around the city, including Kartoffelrækkerne in Østerbro and Humleby in Vesterbro, before it was dissolved in 1972.

The idea of providing good and healthy homes for the poorest part of the city's workforce originated among local politicians and medical doctors during the 1853 Copenhagen cholera outbreak which killed approximately 5,000 citizens.

A major reason for the outbreak was the dismal conditions in the poorest parts of the city which suffered from overpopulation and lack of proper sanitary facilities.

The Worker's Building Society was founded in 1865 on the initiative of the medical doctors Emil Hornemann (1810–90) and Frederik Ferdinand Ulrik (1818–1917) who had witnessed first hand how far conditions could deteriorate, but it also drew on possible reforms in health care and housing.

Considerably younger, they also demonstrate the general improvements in housing standards, with more practical floor plans and fittings, such as built-in China cabinets.
