Description

Redheath is a country house that has been converted into a school. The front range was added in 1712 for C. Finch to an earlier 16th-century house that is no longer standing. The building was altered in 1743 and further extended and modified in 1866 for H.C. Finch, with additional extensions made in the 20th century. It is constructed of brown-red brick with lighter red brick dressings and features a hipped tiled roof. The house has nine bays and is one room deep, rising to three storeys. The central three bays project slightly, with a central entrance that includes an eight-panelled door surrounded by a rusticated surround, vermiculated blocks on Roman Doric pilasters, and richly carved brackets supporting a semi-domed hood.

The building has a moulded plinth and glazing bar sashes set in moulded flush frames, with gauged brick flat arched heads. The windows flanking and above the entrance are scalloped. There is a cyma reversa plat band over the ground floor and cyma recta floating cornices above the central first-floor windows. The outer sections have an ovolo plat band over the first floor. Small nine-pane sashes are present on the second floor, with '1712' cut into the brick in a recessed apron below the central window. The eaves cornice is also notable.

A central cupola sits on the ridge, which is a 20th-century replacement of the original from 1743. This cupola features a square drum with a moulded cornice, an octagonal bell turret supported by Roman Doric columns, and an ogee leaded dome topped with a weathervane finial. The right return has three bays with plat bands and altered openings. The ground floor has two sashes, while the first floor features a central cross casement, a small vertical casement to the right, and a blind opening to the left. The second floor includes a two-light central casement and a one-light casement to the right, with a blind opening to the left.

The left return has two bays with plat bands and glazing bar sashes, along with blocked cellar windows. The rear wall has altered openings and brickwork, with a ground floor lean-to addition at the centre. There are 19th-century stacks on the rear ridge and a one-storey 19th-century block to the rear left, which has three bays, a glazed entrance, flanking sashes, and a roof hipped to the rear. Inside, there is some original bolection moulded fielded panelling on the ground floor and a stone fireplace in the hall. The 20th-century additions are not of special interest.
