Citibank House is an 18-storey office building in Perth, Western Australia. The 224 ft building was opened in 1962 as the T & G Building, and was the tallest building in Perth until 1970 when Hamersley House was opened. It underwent a major refurbishment in the 1980s which significantly altered the building's external features. The building adopted its current name when Citibank became its flagship tenant. As of December 2008, the tower is the 26th-tallest completed building in Perth.
