BP building

The BP Building, previously also known as the Axa-Royale Belge Tower, is a suspended-structure office building in Antwerp, Belgium, designed by the Belgian architect Léon Stynen. The building was completed in 1963 and features a unique cantilevered floor structure and cable supports. All of the floors are supported with external cables that are attached to roof beams: the weight of roof beams, all floors, and the external walls are carried by a center core. The building was commissioned by BP and is still referred to as the "BP Building", but is now owned by Buysse & Partners Smart Assets since 2018. Its architecture has been classified as Modernist and Brutalist.
