Streets in the sky, prefabricated panel housing estates, raw concrete flying saucers, tower blocks shaped like corn cobs: these are some of the constructions that recast the urban landscapes of Eastern and Central Europe after the Second World War. The volume lets readers explore and learn about the brutalist and modernist architecture erected in the former Eastern Bloc and in ex-Yugoslavia, and build paper models of some of the most intriguing buildings, from the massive estates of Moscow to the skyline of Tbilisi.
