Castle Hill House

Castle Hill House is a large house, now divided into apartments, dating from the 18th century with 19th-century additions. It is constructed of red brick with peg-tiles and slates and has a U-shaped plan, extending over two and three storeys with attics and cellars.

The west-facing front elevation features three bays and two storeys, topped by a parapet with a stucco band. Behind the parapet are gabled, hipped peg-tiled roofs, each with a large red brick stack. A single-storey, flat-roofed porch, built in the 19th century and matching the brickwork, projects from the centre, with a 19th-century door, upper glazing, and a lower panel. Doorways and windows have brick voussoirs, and all windows are sash windows with 4x4 panes. An external brick stack from the 19th century is adjacent to the porch on the south side.

The south garden elevation is divided into two units, with the main unit to the west mirroring the front elevation and featuring a large three-bay window across both storeys. The ground and first-floor windows are sashes with 4x4, 3x4, and 4x4 panes respectively. A deep first-floor balcony, dating from around 1900 with a brick balustrade, is also present. Below the balcony is a French window with four 4x6 panes and a glazed overlight of 5x2 panes on each side, alongside a sash window with 2x4 panes. A first-floor casement window has glazing bars in a pattern of 4x6 panes and a 4x1 pane overlight. To the east is a slightly set-back lesser unit with two bays, two storeys and a cellar, with a gabled, peg-tiled roof, a central stack, and 3x4-paned sash windows. A cellar window is a sash with 2x4 panes.

The north side features the front unit with a style similar to the front elevation, a hipped roof with two dormer windows, and a stack towards the rear behind the ridge. The window range is irregular, and the walling shows evidence of alteration. The windows are sashes, with four 3x4-paned sashes, one 4x4 sash with some old glass, and one triple sash with a segmental head, having 1x4, 2x4, and 1x4 panes. The rear unit is parallel to the south side, but separate, with a hipped slate roof and two 3x4-paned sashes.

The rear, east-facing elevation is on sloping ground, with gabled, three-storey elevations on the rear units and a single bay of the front block between. A first-floor doorway is approached by steps, leading to a 20th-century door and overlight. A 3x4-paned sash window is on the second floor. The south wing is blank and partly obscured by a 20th-century extension, while the north wing has a central exterior stack to the south and a shallow three-storey lean-to addition on the south side. Ground floor features a 20th-century door and two sash windows on both the first and second floors.

The interior has been considerably altered in the 20th century, but a central, late 19th-century staircase retains a shaped handrail, turned balusters, Tuscan newel posts, and a similar dado. The first-floor landing features an arcaded wall in a Jacobean Ionic style and doorways with cornice hoods and gadrooned friezes, along with fielded panel doors.
