English: A large-scale municipal housing complex built by the Social Democratic Party government during the period commonly known as "Red Vienna". It was part of a program for social reform. The Karl-Marx-Hof's monumental appearance, richly expressive colors, and public ststue form a symbol that promises a new life for the working class. Combined with the innovative planning of kitchens with running water, residential units with balconies, and the integration of the residential units with public service facilities, the worker families living here can enjoy a life that was previously limited to the middle class.
