Gilbrook House, Including House Adjoining South-West

Gilbrook House, including the house adjoining to the south-west, is a detached house built around 1800, which incorporates cob walls from an earlier building of indeterminate date. The structure features plastered cob on stone footings, with the first floor being timber framed and lath and plaster infill. It has a Kingsbridge slate gabled-end roof and is likely designed as a three-room, cross-passage house plan that was completely reorganised and heightened around 1800. The house has a single depth with two later brick rear wings and two rear stacks with brick shafts. During repairs in 1967, traces of a left-hand end stack were uncovered.

The house is two storeys high and has an almost symmetrical front with a five-window range, featuring a modillion cornice. On the first floor, there are three 12-pane hornless sash windows alternating with two tripartite 4:16:4 pane hornless sash windows. The ground floor has a central doorcase under a broken pediment, flanked by pilasters decorated with paterae, and features panelled reveals and a soffit to a round-headed arch. The entrance includes a fielded panel door with a traceried semi-circular fanlight. To the left of the door, there is a tripartite sash window and a 12-pane sash window, while to the right, there is another tripartite sash and an additional doorway. The building has rusticated quoins, with the right-hand quoin set back slightly from the angle, and the cornice does not extend exactly to the right-hand corner.

At the rear, the wings contain some sash windows under segmental window arches. Inside, there are some joinery features from around 1800, including fielded panel doors, and the main reception room has two round-headed alcoves on the rear wall. Attached to the house is a substantial cob barn with a pantiled gabled-end roof. One of the front garden walls, which forms the rear wall of an adjacent building, is decorated with six small and two large brick round-headed recesses.
