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.[3]

Design

In 1963, well-known Belgian architect Leon Stynen experimented with a technique which allowed a cantilevered facade. All of the floors and the facade of the building are held up with steel cables which are supported from rooftop beams. The design allows for a greater unobstructed interior space.[4] It was Europe's first building which made use of "suspended construction".[3]

The floors are supported by external cables, which allows each floor to have no internal columns. The ten floors are all similar and divided by interior wood-based walls. The facade is a type of curtain wall with metal grids. A restaurant is located on the upper level of the building.[5]

The center concrete columns are 57 metres (187 ft) tall, and in addition to supporting the stairway and the duct work, they also support the steel core of two 55-metre (180 ft) beams. Nine crossbeams, 18 metres (59 ft) long, run perpendicular to the two primary beams. Cables are then hung from the crossbeams, and these support the floors.[3]

Axa-Royale Belge Tower

The building was purchased by Axa Bank Belgium and renamed the Axa-Royale Belge Tower.[6][7] It underwent a major renovation and most of the original interior is now replaced.[3]

On 5 March 2001 the building was classified as an architectural monument based on historical and architectural value.[8]
