Designed by John Smith Murdoch and a team of assistants from the Department of Works and Railways, the building was intended to be neither temporary nor permanent—only to be a "provisional" building that would serve the needs of Parliament for a maximum of 50 years. The design extended from the building itself to include its gardens, décor and furnishings. The building is in the Simplified or "Stripped" Classical Style, commonly used for Australian government buildings constructed in Canberra during the 1920s and 1930s. It does not include such classical architectural elements as columns, entablatures or pediments, but does have the orderliness and symmetry associated with neoclassical architecture.
