Architecture of Australia
|Part of a series on the|
Australian architecture has generally been consistent with architectural trends in the wider Western world, with some special adaptations to compensate for distinctive Australian climatic and cultural factors. Indigenous Australians produced only semi-permanent structures and during Australia's early Western history, it was a collection of British colonies in which architectural styles were strongly influenced by British designs. However, the unique climate of Australia necessitated adaptations, and 20th-century trends reflected the increasing influence of American urban designs and a diversification of the cultural tastes and requirements of an increasingly multicultural Australian society.
Notable Australian architectural adaptations include the Queenslander and Federation styles of residential architecture. Iconic Australian designs include the UNESCO listed Sydney Opera House, Melbourne Royal Exhibition Building and the 11 remnant penal colony sites selected for World Heritage protection in 2010.
In the period before European settlement of Australia in 1788, evidence of permanent structures built by Indigenous Australians in Australia was limited as the Indigenous population did not build establishments that were commonly recognised by the European Settlers. Tents and wattle and daub huts preceded more substantial structures. As a British colony, the first European buildings were derivative of the European fashions of the time. As most of the colonialists where from England the first buildings reflected English ideas.
Georgian architecture is seen in early government buildings and the homes of the wealthy. The architect Francis Greenway, who appears on the Australian ten-dollar note designed early buildings in the Georgian style. Examples include the Hyde Park Barracks, St James' Church and St Matthews Church at Windsor.
Another European style to gain favour in 19th century Australia, particularly in churches, was Gothic Revival architecture. Pointed arches, turrets, battlements and gothic ornaments could also be found on bank, insurance offices, university buildings and homes. One of the best examples of this style can be seen at the lower end of Collins Street in Melbourne.
With the Australian gold rushes of the mid-19th-century major buildings, largely in Melbourne and Sydney and to a lesser extent in regional capitals such as Ballarat and Bendigo were built in the style of Victorian architecture. From about 1850 to 1893 Italianate architecture was also popular as it allowed greater displays of prosperity through rich and ornate decorate features such as cast iron lace work and slate roofs. Towards the end of the century the style was pushed to an extreme by some architects. Buildings became over-burdened with excess columns, balustrades, exaggerated entrances and other lavish decorations. Medley Hall in Carlton is an example of this style which became known as the Boom Style from 1880 to 1893.
One of the most significant architectural movements in Australian architecture was the Federation architecture style of the turn of the 20th century, where Australia began to play with the idea of a "style of our own", and the modern styles of the late 20th century which sought to reject historicism.
Walter Burley Griffin was an American architect and landscape architect who played a key role in designing Canberra, Australia's capital city. A legacy of his unique building designs remains in a small number of Melbourne buildings and the Sydney suburb of Castlecrag. Castlecrag was planned by Griffin and also features a number of houses designed in the organic Modernist style he developed after the Prairie School architecture that marked his earlier career in the United States. The simple, flat-roofed cottages that Griffin built in Canberra used his innovative, patented techniques for concrete construction.
One of the most important local introduction to Australian architecture was the verandah. As pastoralists took up land and built solid, single story dwellings the addition of verandahs proved popular as they provided shade and looked attractive. They were often integrated into the symmetry of Georgian style homes.
Like elsewhere in the world, socio-political factors have played their roles in shaping Australian architecture. During the early 20th century, cities across Australia had placed building height limits, typically 150 feet (45 m), thus hampering the development of American-style skyscrapers until the limits were lifted in the late 1950s. Likewise the popular notion of the "Australian Dream", in which families seek to own their free-standing houses with backyards, meant that high-density housings were rare in Australia until the end of the 20th century. The design of housing in Australia after World War II, which was mostly undertaken by builders, has been described as poor aesthetically and environmentally.
Significant concern was raised during the 1960s, with green bans and heritage concerns responding to the destruction of earlier buildings and the skyscraper boom, particularly in Sydney. Green bans helped to protect historic 18th-century buildings in The Rocks from being demolished to make way for office towers, and prevented the Royal Botanic Gardens from being turned into a carpark for the Sydney Opera House. In Melbourne a battle was fought to preserve historic Carlton, Victoria from slum reclamation for public housing, while gentrification played a big part in the suburb's salvation.
In the 21st century, many Australian architects have taken a more Avant-garde approach to design, and many buildings have emerged that are truly unique and reflective of Australia's culture and values. As a result, many Australian practices are beginning to expand their influence overseas rather than the reverse which was often the case. Melbourne is seen as the city at the forefront of design ideas. Sydney is focusing on the humanist approach tending towards minimalism and architecture in Queensland is interested in outdoor rooms and the filtering of light.
Australian architectural styles 
Buildings were often heavily influenced by the origins of their patrons, hence while the British would like to be reminded of their Gothic churches and Tudoresque cottages of a perfect England, the Dutch, German, Polish, Greek, Italian and other nationalities would also attempt to recreate the architecture of their homelands.
