Brisbane Square

Brisbane Square is a high-rise building in Brisbane, Queensland, Australia. The building has 38 floors and rises to 151 metres. The building's main use is for office space, with the lower floors leased to retailers, with a 350-space car park below the building. Significant tenants include the Brisbane City Council (floors 1-23) and Australian Retirement Trust (floors 24-37).

Brisbane Square is situated on the block bounded by William Street, George Street, Queen Street and Adelaide Street. The building faces the Conrad Treasury Casino on Queen Street and formerly, the Law Courts Complex on Adelaide Street.

Design
Brisbane Square is owned by ABN AMRO and was designed by international architects Denton Corker Marshall. The Civil and Structural engineers for the project were Qantec McWilliam consulting engineers. Two of the four distinctive, rectangular, coloured spaces near the base of the building contain the new Brisbane City Council and Brisbane Square Library. Brisbane Square is the largest commercial office building in Australia to have been awarded a 5 star Green Star rating. The original development application included a number of residential floors on the top of the building, however, this was rejected on the basis that noise levels would be excessive.

Construction
Construction was completed in late 2006. The project was constructed by Baulderstone Hornibrook.

The site of Brisbane Square was previously occupied by the now-demolished Prudential Building, state headquarters of the British insurance company Prudential Assurance Co. The 6-story art deco styled Prudential Building was completed in 1958.

Tenants
The Brisbane City Council operates a public library in Brisbane Square.
