Berlin Modernism Housing Estates (German: Siedlungen der Berliner Moderne) consists of six subsidized housing estates (Siedlungen) that testify to innovative housing policies from 1910 to 1933, especially during the Weimar Republic, when the city of Berlin was particularly progressive socially, politically and culturally. The properties are outstanding examples of the building reform movement that contributed to improving housing and living conditions for people with low incomes through novel approaches to town planning, architecture and garden design.
