Description
Dean House is a small country house built in the 18th and 19th centuries. It is constructed of brick, which was once colourwashed, and has a slated roof with lead ridges. The main structure is a three-storey building with five bays on each side, featuring 19th-century bows added to each corner, a canted single-storey bay in the centre of the sides, and a rectangular single-storey extension at the front.
The front extension includes a central pedimented Ionic porch supported by brick bases, set within a slightly projecting canted bay. On either side of the porch are 20th-century equal tripartite sash windows. The building has a moulded brick cornice and a parapet above the windows and doors, with balustraded sections and stone copings topped with balls at the corners of the canted centre.
On the first floor, there are five 18th-century 12-pane flush framed sashes with rubbed brick arches and a raised brick architrave around the central windows. Above this, there is a moulded brick cornice and five small 12-pane sashes on the second floor, with the moulded and dentilled timber cornice interrupted by the second-floor windows. The roof is hipped, featuring 19th-century stacks at either end along the return ridge. The house was formerly the home of Sir Ivor Spencer Churchill.
