Seven-storey ‘cloud’ over heritage buildings in central Sydney

The seven-story office addition rises above the rooftop of a 1908 warehouse and cantilevers over a heritage-listed electricity substation. The striking architectural design comprises concrete floors wrapped in a curved glass façade, appearing to ‘float above’ the existing buildings.

The site stretches between Clarence and Kent Streets. The former substation has a five-storey façade on Kent Street, with six storeys on Clarence, and features a purpose-built three-storey machine room at the basement level. The cantilever design of the new addition is made possible by adding a new building core at the south of the warehouse, limiting structural additions to the substation and allowing for retention of the machine room.
