 Housing projects like the Narkomfin were designed for the attempts to reform everyday life in the 1920s, such as collectivisation of facilities, equality of the sexes and collective raising of children, all of which fell out of favour as Stalinism revived family values.The styles of the old world were also revived, with the Moscow Metro in particular popularising the idea of 'workers' palaces'.By the end of the 1920s Constructivism was the country's dominant architecture, and surprisingly many buildings of this period survive.
