The home of the Dundas family since the Middle Ages, it was sold in the late 19th century and is currently the residence of politician and businessman Sir Jack Stewart-Clark.

The tower house and the adjoining Tudor-Gothic mansion are listed separately as Category A buildings,[1][2] and the grounds are included in Inventory of Gardens and Designed Landscapes in Scotland.

[6] In 1416, James Dundas obtained a licence from the Duke of Albany (then the effective ruler of Scotland) to build a keep.

[8] On 13 August 1553 in the great hall, James Dundas gave his infant daughters Elizabeth and Jane gifts of silver plate.

[10] In 1818, James Dundas had the 17th century portion of the building pulled down and rebuilt in a Tudor-Gothic style by the renowned architect William Burn.

[11] It was again sold in 1899, when it was bought along with five farms and 1,500 acres (600 hectares) of agricultural land by Stewart Clark, the owner of a Renfrewshire textile company and a respected philanthropist.

The Keep, uninhabited for over 300 years, had its parapet rebuilt and its stonework restored, and it was installed with electricity, heating, toilets and a kitchen.
