Description
Forton House is a large house built in the early 19th century. It features painted brick and a slate roof. The main block is tall and has lower extensions at the rear. The front, facing southwest, has a regular but not symmetrical design with three storeys and three windows. It has a low-pitched hipped roof with wide eaves supported by coupled carved brackets. The walls include slightly-cambered openings, a moulded stucco cill band on the second floor, and stone cills. The windows are sashes set in reveals, with one casement in an altered ground floor window on the southeast side. The entrance is a triangular-headed doorway within a stucco porch supported by two plain columns, leading to a six-panelled door. The southeast elevation features three widely spaced large openings on two floors, with similar details: sashes on the first floor above French windows that open onto a terrace. The two windows on the northeast side are enclosed within a trellis verandah, which is glazed at each end and has a hipped slate roof. The other elevations have a more vernacular style, with irregular window sizes and patterns.
