Designed by the architectural firm Godfrey & Spowers, it is a modernist building. It previously served as the headquarters for BHP Billiton, and the company's sign on the outside of the structure was the highest in the country. BHP has since moved to a new building across the city in QV Village.
The building's most obvious feature on the skyline is its sloped roof, which hides various communications equipment. The structure's facade is 170,000 m² of laminated glass.
