Castlemilk House was an 18th century country house and estate located in Carmunnock parish, south of Glasgow, Scotland. The house was built around the 15th-century Castlemilk Tower, but was demolished in 1969 after its use as children's home had ended the previous year.
The lands of Cassilton of Carmunock were acquired by the Stuarts of Castlemilk in Dumfriesshire in the 13th century, and in the 16th century they renamed the estate Castlemilk.
In 1937 the estate was acquired by Glasgow Corporation for housing (under a compulsory purchase order, due to the Laird's misgivings over the land being used for high-density housing so far from locations of industry), but the outbreak of the Second World War delayed building work - the Castlemilk housing scheme was constructed in the 1950s, and soon modern tenements surrounded the house's grounds on all sides.
The mansion was acquired by Glasgow Corporation in 1939, and was used to accommodate evacuees from the city until the end of the war. It was then used as a children's home from 1948 until the expense of maintaining the house forced it to close in January 1969. Castlemilk House was demolished in 1969; a children's play area now occupies the site.
Other than a small park featuring the landscaped fish pond and a stone bridge (1833, Category B listed) which once formed the driveway to the mansion, and the driveway entrance gateways which are sited to the north-east, on the edge of Rutherglen, the accompanying stables block (built 1794, designed by David Hamilton, also Category B listed) is the main surviving legacy of the grand estate.
After being damaged by a fire in 1994, it was restored in 2007 (with the project winning awards) and now contains the local housing offices, community facilities and a nursery.
