Federation architecture is the architectural style in Australia that was prevalent from around 1890 to 1915. The name refers to the Federation of Australia on 1 January 1901, when the Australian colonies collectively became the Commonwealth of Australia.
The architectural style had antecedents in the Queen Anne style and Edwardian style of the United Kingdom, combined with various other influences like the Arts and Crafts style. Other styles also developed, like the Federation Warehouse style, which was heavily influenced by the Romanesque Revival style. In Australia, Federation architecture is generally associated with cottages in the Queen Anne style, but some consider that there were twelve main styles that characterized the Federation period.
The Federation period overlaps the Edwardian period, which was so named after the reign of King Edward VII (1901–1910); however, as the style preceded and extended beyond Edward's reign, the term "Federation architecture" was coined in 1969.
Federation architecture has many similarities to Edwardian Baroque architecture; however, there are significant differences that distinguish the Federation architecture style from the Edwardian Baroque architecture style, particularly due to the embracing of Australiana themes and the use of the verandah in domestic settings. Australian flora and fauna are prominently featured, and stylised images of the New South Wales waratah,flannel flower, Queensland firewheel tree, and other flowers, and the kangaroo,kookaburra, and lyrebird, were common. The Coat of Arms, and rising sun, representing a new dawn in the country of Australia, also appeared regularly on gables.
