Cumbernauld House is an 18th-century country house located in Cumbernauld, Scotland. It is located near in the Cumbernauld Glen, close to Cumbernauld Village, at grid reference NS772759. The house is situated on the site of Cumbernauld Castle, which was besieged by General Monck in 1651. It was built in 1731, to designs by William Adam (1689–1748), for John Fleming, 6th Earl of Wigtown. In the later 20th century the house was used as offices, first by Cumbernauld Development Corporation, then North Lanarkshire Council, and latterly by DH Morris, who went into liquidation in March 2007. Since then the building has lain dormant.
