The Exzenterhaus is a commercial office building in Bochum, Germany.[2] Designed by architect Gerhard Spangenberg, the building was constructed on top of an air raid shelter built during the World War II era.[2]

Overview

The cylindrical bomb shelter stands 22 metres and was constructed in 1942.[2][4] The structure was built with 520 beds and 52 seats, but would accommodate more than 3,000 people during air raids on Bochum.[4] The bunker was left empty for many years following the war.[4] The city sold the bunker to the builder of the Exzenterhaus for €670,000.[5] Construction on the building started in 2009 and was completed in 2013.[2] The building rises 15 storeys above the top of the bunker and at an overall height of 90.5 metre, it is the tallest building in Bochum.[2][6] The name Exzenterhaus literately means "eccentric house" in German, which itself is derived from the latin phrase "ex centro", meaning off-centre.[7]

The newer portion of the structure is separated in three different five-storey sections shaped like polycentric rings, each which cantilever up to 4.5 meters, giving the impression of a twisting structure.[8][2] Each of the top fifteen storeys features a balcony when extends in the direction that floor's section's cantilever.[7] The first two floors of the bunker portion of the structure contains a reception area, while the remainder of this portion is used for archival and storage purposes.[2] It is located adjacent the Oskar-Hofmann-Straße station of the Bochum Stadtbahn.
