Dumfries House is a Palladian country house in Ayrshire, Scotland. It is located within a large estate, around 3 km west of Cumnock. It was built in the 1750s by John Adam and Robert Adam for William Dalrymple, 5th Earl of Dumfries, and inherited in due course by the Marquesses of Bute, in which family it remained until 2007. It is notable for having preserved much of its original 18th-century furniture in situ, some of which was specially commissioned for the house from Thomas Chippendale.
