The Hansaviertel is a Berlin district between Tiergarten park and the Spree River. It was almost completely destroyed during World War II, but was rebuilt from 1957 to 1961 as a housing estate project by international master architects like Alvar Aalto, Egon Eiermann, Walter Gropius, Oscar Niemeyer, Sep Ruf. The whole ensemble called Interbau, is now protected as a historic monument.

This model apartment building was built as a part of an international architecture exhibition that was held in Berlin in 1957.
