Government House is the official residence of the Governor of Western Australia, situated in the central business district of Perth (the state capital). It was built between 1859 and 1864, in the Jacobean Revival style.
Government House is located on St Georges Terrace (Perth's main thoroughfare), sitting on the same block as Council House and the Supreme Court buildings. The site has been used by governors since the establishment of the Swan River Colony in 1829, with the current structure built to replace an existing wooden building. The buildings and gardens of Government House are of exceptional heritage significance, being listed on the Western Australian Register of Heritage Places and classified by the National Trust. They are regularly opened for public viewing.
The building is a two storey mansion in the early Stuart or Jacobean Revival style set on 32,000 square metres of English gardens in the centre of the Perth business district, between St. Georges Terrace and the Swan River. The unique architectural character of the building is characterised by the use of stonework and bonded brickwork, incorporating square mullioned windows, decorated gables and ogival capped turrets. The attenuated gothic arcading at ground floor level derives from another form of Victorian Revival expression Fonthill Gothic. The building has 16 rooms on the ground floor and 25 on the first floor. According to the Western Australian Register of Heritage Places Assessment, Government House is a 'unique example of a Victorian Gentleman's residence' set in landscaped gardens with mature plantings and a number of commemorative trees.
