William Danby (1752–1833) almost entirely rebuilt the house, at first by John Carr, architect of York, in 1764–67. Danby altered and extended the house, giving it the Gothic aspect it retains, in two building campaigns, to designs of the Yorkshire mason-architect John Foss of Richmond (1745–1827), who became a close personal friend. In the first, of 1791–96, the north range was added. A design for the Drawing Room, at least, was contributed by James Wyatt. In a second building campaign, of 1813–14, again under the direction of Foss, the south wing was built. The house included a handsome library.
