The film City of Tomorrow by Korpys/Löffler was made in conjunction with the 50th anniversary of the Interbau 1957 in the Hansaviertel in Berlin Tiergarten as part of a larger installation in the Akademie der Künste. As an extension to the exhibition Korpys/Löffler rented the glass basement of Paul R. Baumgarten's Eternithaus. One morning they removed one of the 7.5 m long tree trunks from the bulkheads of Object 13, an eight-storied apartment building by Egon Eiermann, and walked with the trunk on their shoulders in a kind of procession through the Hansa Quarter to the Eternithaus. Once there, Korpys/Löffler used the trunk to manipulate a number of selected design items and objects documenting this process through photographs. The moving images, taken by the artists as they walked along the quarter, merge in an integral way with the film images from 1953, taken by an anonymous cityscape chronicler, who extensively filmed the remaining houses and ruins of the Berlin Hansaviertel, built in the 1880s. On the foundations of these ruins, a prestigious social housing estate was built from 1957 onwards as a symbol of the German new beginning, the so-called "City of Tomorrow".
