AUD 231 million extension of the Art Gallery of New South Wales in Sydney, designed by Pritzker-Prize-winning firm SANAA, opened to the public on 3 December. The project includes a standalone building connected to the late-19th-century museum via a garden, which will double the gallery’s exhibition space. There will also be an underground gallery housed in a Second World War fuel tank, with a display area of 2,200 sq m. The new structure has been awarded a 6-star Green Star design rating by the Green Building Council of Australia. The New South Wales was founded in 1872 on a site overlooking Sydney Harbour. It is regarded as the most important public gallery in Sydney, and one of the largest in Australia.
