ABSTRACT The Finnish Housing Reform Association was set up in 1910 to promote public housing with new social ideas in housing design. After World War I, the association took the initiative to design affordable housing for the district of Käpylä in Helsinki. Construction was postponed by the years of instability that followed the Civil War of spring 1918. In early 1920, the City of Helsinki organised the subscription of shares in the People's Housing Company Ltd. Four– or two–family houses and even dwellings consisting of a room and a kitchen were a huge improvement to rental barracks. The quality of housing further enhanced by garden plots and communal saunas. Construction of the district resulted in notable stylistic variety. The scale of the area and the new efficient timber construction system that aimed at affordability and short construction times made Wooden Käpylä exceptional. In 1960, a design competition was organised that, had it gone ahead, would have meant the destruction of the Käpylä. The competition drew sharp criticism, and in 1971 Wooden Käpylä became protected in the master plan. Today, the street plan offers surprising views and a sense of freedom relative to previous as well as concurrent enclosed blocks.
