This building was constructed in 1924-1925 according to plans from 1923 and is special in many ways. At that time almost no houses with flat roofs were built in Central Europe. The architect Jiří Kroha uses some forms of Cubism, a style that was widespreaded in Czechoslovakia in the early 1920s, but reduces it in the forms and also achieves something constructivist with his nesting cubes, protruding oriels, and the ribbon windows. Being a left-wing architect, it is possible that he took up the theoretical concepts of the constructivists in the Soviet Union. This thesis has not yet been formulated.
Even tough that this building is considered as a important milestone in modern architecture, it is not listed (yet).
