Parliament House, Legislative building in West Perth, Australia

Parliament House in West Perth is a legislative building designed in Federation Academic Classical style, constructed with Rottnest Island brick, Donnybrook stone, and jarrah timber throughout. The structure contains both chambers with public galleries, formal ceremonial spaces, and traditional parliamentary rooms.

An 1897 Royal Commission proposed housing both houses in one building; after a nationwide design competition judged by New South Wales's government architect, the Public Works Department design by John Grainger and Hillson Beasley was chosen. Construction began in 1902 and the building opened on 28 July 1904. The eastern wing followed between 1958 and 1964, and a southern extension was added in 1978.

The Legislative Council chamber shows how local building materials mix with traditional British parliamentary design, reflecting Western Australia's constitutional identity. The interior spaces demonstrate how the region connected its own resources with classical English forms.

Visitors can watch parliamentary sessions from public galleries on sitting days and join guided tours to understand how legislation works. The tours provide access to the main chambers and show visitors the key rooms where government business takes place.

The western facade displays replica statues of the Lion and Unicorn from Westminster, gifted in 1936 by the Empire Parliamentary Association. These symbols visually connect the building to the birthplace of British democracy.
