Brisbane
Architecture

Brisbane has a number of heritage buildings, some of which date back to the 1820s, including The Old Windmill in Wickham Park, built by convict labour in 1824, which is the oldest surviving building in Brisbane, and the Commissariat Store on William Street, built by convict labour in 1828, which was originally used as a grain house, and is now the home of the Royal Historical Society of Brisbane and contains a museum. Other 19th and early 20th-century buildings of architectural significance include the Treasury Building, City Hall, Customs House, Land Administration Building, MacArthur Chambers, The Mansions, National Australia Bank Building, and the Federation-style People's Palace, a former temperance hotel on Edward Street.

Queenslander -style housing is common in Brisbane. Queenslander homes typically feature timber construction with large verandahs, gabled corrugated iron roofs, and high ceilings. Most of these houses are elevated on stumps (also called stilts), traditionally built of timber, which allow for a void under the houses which aids in cooling. The relatively low cost of timber in south-east Queensland meant that until recently, most residences were constructed of timber, rather than brick or stone. Early legislation decreed a minimum size for residential blocks leading to few terrace houses being constructed in Brisbane. The high-density housing that historically existed came in the form of miniature Queenslander -style houses which resemble the much larger traditional styles, but are sometimes only one-quarter the size. These houses are most common in the inner-city suburbs.

Brisbane is home to several of Australia's tallest buildings. All of Brisbane's skyscrapers (buildings with a height greater than 150 m (490 ft)) are located within the CBD, but the inner suburbs are also home to a number of high-density buildings, Torbreck being the first high-rise and mix-use residential development in Queensland. Brisbane's 91-metre City Hall was the city's tallest building for decades after its completion in 1930 and was finally surpassed in 1970, which marked the beginning of the widespread construction of high-rise buildings.

Brisbane's tallest building is currently Brisbane Skytower, which has a height of 270 m (890 ft). Architecturally prominent skyscrapers include the Harry Seidler -designed Riparian Plaza, One One One Eagle Street, which incorporates LED lighting resembling the buttress roots of the Moreton Bay fig, and 1 William Street, the headquarters of the Queensland Government.
