PROJECT DESCRIPTION
A renovated 1916 heritage building, nicknamed the ‘Money Box’, with a new office tower extension, featuring a cantilevered 10-storey section projecting 22 metres over the heritage buildings. The new building’s efficient structural steel frame, featuring V-shaped bracing and suspended columns in tension, has allowed the existing buildings to be free of any structural intervention. The new building also incorporates sustainable features such as rainwater harvesting and high-performance glazing.
Judge's comment: The judges were impressed by the ability of the team to design a complex cantilevered construction on a restricted city centre site both adjacent to, and overflying, heritage buildings. The highly complex structural challenges have been met by a combination of elegant design solutions and pragmatic construction sequencing in order to achieve maximum value for the client, and in particular the use of post tensioning in the frame, composite steel and concrete construction of the compression tubes, and temporary support from the heritage building during construction. .
