Germany

Between 1925 and 1930 Germany was the site of innovative and extensive municipal public housing projects, mostly in Berlin, Cologne and Frankfurt am Main. These Siedlungen (settlements), were made necessary by the dreadful living conditions of pre-war urban tenements. The right to a healthy dwelling was written into the 1919 Weimar Constitution, but few dwellings were built until economic stability in 1925.

These settlements were low-rise, no more than 5 stories, and in suburban settings. Residents were provided access to light, air, and sun. The size, shape, orientation and architectural style of Germany's public housing were informed by the recent experience of the Vienese and the Dutch, the anti-urban Garden City Movement in Britain, by new industrialized mass-production and pre-fabrication building techniques, by the novel use of steel and glass, and by the progressive-liberal policies of the Social Democrats.

Architect Martin Wagner (with Bruno Taut) was responsible for the thousands of dwellings built in and around Berlin, including the Horseshoe Siedlung (named for its shape), and Uncle Tom's Cabin Siedlung (named for a local restaurant). But Wagner was second to the city planner Ernst May in Frankfurt. May was responsible for the construction of 23 separate settlements, 15,000 total units, in five years. He ran his own sizable research facility to investigate, for instance, air-flow in various floorplan configurations, construction techniques, etc. The Austrian architect Margarete Schütte-Lihotzky applied the principles of Taylorism to the kitchen workspace and developed the Frankfurt kitchen while working for Ernst May.

Beyond technical research May also published two magazines and embarked on a significant public-relations project, with films and classes and public exhibitions, to make Neues Bauen acceptable to the public. In the late 1920s the principles of equal access to "Licht, Luft und Sonne" and the social effects of a guaranteed ""Existenzminimum" became a matter of lively popular debate all over Germany. One indirect result of this publicity was the American housing movement: a young Catherine Bauer attended one of May's conferences in 1930, and wrote her seminal "Modern Housing" based on research done in Frankfurt and with Dutch architect JJP Oud.

Increasing pressure from the rising Nazis brought this era to an end in 1933. A majority of the German public housing experts had Social Democrat or Communist sympathies and were forced out of the country.
