Harpers Mansion

Harper's Mansion is a heritage-listed house and now house museum in Berrima, Wingecarribee Shire, New South Wales, Australia.It is recognised for its Georgian design.

Harper's Mansion is now a property of the National Trust of Australia (NSW), which acquired it in 1978. It was added to the New South Wales State Heritage Register on 1 March 2002.. James Harper and his wife Mary bought his first block of land in Berrima in 1832 on which he built the Surveyor General Inn in 1834, becoming its licensee in 1835. He was a Sutton Forest publican and that district's Chief Constable until 1835. In 1834 he purchased the 100 acres (40 ha) on which he built what is now called 'Harper's Mansion', which was most likely built in 1835-36.

The house was built with a single storey verandah and a detached brick kitchen. By 1844 there was also a stable block and a fenced garden.. The 100,000 clay bricks were made on-site and the Trust believes that the stone was quarried locally. At the time, tradesmen were building the court house and jail, and James may have used them. The National Trust thinks that the house was built from the pattern book of a Georgian townhouse, which was common in the colony.
