The Standard Bank Centre (also known as the Hanging Building or the 78 Fox Street)[1] is a skyscraper in Johannesburg, South Africa.

[3][7] The challenge for the designers - the German architect Helmut Hentrich (1905–2001) and the Austrian architect Hubert Petschnigg (1913–1997), who planned the skyscraper in collaboration with the British-Danish-Norwegian engineer Ove Arup (1895–1988) - was to find a spacious square in the crowded Johannesburg CBD to anchor an office building.

A special slewing crane was designed for the project to lift and mount a quarter of each floor level.

Concrete was delivered by night to the construction site to minimize traffic obstruction.

The windows use tinted glass with laminated double glazing for sunlight protection.
