Citibank House is an 18-storey office building in Perth, Western Australia. The 224-foot (68 m) 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.
