The CAGA House was a 30-storey skyscraper in Sydney, NSW, Australia. When it was completed in 1977, it was the 10th tallest building in Sydney. The building stood for 15 years before being dismantled to make way for the Governor Phillip Tower. It was the tallest building in Sydney to be demolished until the nearby State Office Block was pulled down to make way for the Aurora Place.
