The site was originally sold in the first Adelaide land sale of 1837, purchased by George Curtis for 12
shillings. In 1861 the site contained a simple two-storey brick dwelling, a wall surrounding the house and a stable. It was purchased by a stockbroker
James Chambers in 1861, who in the same year sponsored the expedition of
John McDouall Stuart, which was launched from the site. A plaque on the property's surrounding wall commemorates the event. The expedition was the first successful European crossing of the continent, but James Chambers died at the property before Stuart's return. In 1862 the site was purchased by businessman, politician and philanthropist
Hugh Robert Dixson (later Sir Hugh Robert Denison), who demolished the existing home, leaving only the wall surrounding the property and the stable. Dixson erected the current grander building in 1897 (or 1901? In 1908, the building was sold to Sir
John Langdon Bonython, editor of
The Advertiser and member of the first Parliament of Australia. Bonython renamed the building "Carclew" after the area in
Cornwall where his ancestors had lived. The property remained in the Bonython family until 1965, when it was purchased by the
Adelaide City Council. After a 2006 architects' report recommending maintenance work on the structure of the building, the
Government of South Australia undertook the construction work, which was completed in October 2009. ==Architecture==
