When the Social Democratic Party of Austria gained control of the municipal administration during Austria's First Republic (1918-1934) (so called "Red Vienna"), it began the project of improving living conditions for workers. A large number of Gemeindebauten, usually large residential estates, were built during that time. Including those buildings that were finished after the events of February 1934, 64,000 apartments where completed, which created housing space for about 220,000 people. Apartments were assigned on the basis of a point system favoring families and less affluent citizens.
