Sunbury Hill Farm

Farmhouse, now a private house, dating to the late 15th century. It was originally a two-story crosswing of a former open hall house, likely built for the keeper of the royal park of Langley, incorporating reused elements from a 13th or 14th-century aisled building. A 17th-century kitchen wing was added to the west, followed by a two-story section on the site of the hall. The house was enlarged to the east, refronted on the south, and a new staircase was added in the early 18th century. It was renovated and recorded around 1977. The rear (north) and east end are timber frame with roughcast rendering, while the front has red brick, along with a brick stable range with a loft above. The roofs are of steep old red tiles.

The house is a two-story, cellar-level structure facing south, with a two-story kitchen and stable range set back to the left, and external end chimneys. The formal south front has a plinth, a moulded brick floor band, and an eaves cornice with a parapet above. Segmental gauged brick arches top the three windows on each floor, with a raised keyblock to the ground floor windows flanking the door, and sunk decoration to the central voussoirs of the arch above the door. Slightly recessed three-light transomed casement windows are present, with a single-light window in the right-hand corner. Four stone steps lead to a four-panel door with a rectangular fanlight, a heavy frame, and a moulded flat hood on heavy shaped brackets. The rear has small-paned casement windows, and a 16th-century outshut features a gabled dormer.

The interior features a large, round-headed recessed cupboard on the axis of the front door, in the form of a coved niche with shaped shelves. Raised and fielded panel doors, a wide arched architrave with a scrolled keystone and entablature projecting centrally, are also present. A cove is painted with a classical subject, dating around 1725, depicting a rider on a horse leading another by the bridle. A contemporary staircase is lit from the west, with a moulded closed string, turned balusters, a moulded handrail, and panelled sides. Panelled window shutters are also a feature.

Visible timber structure is present in the roofspace and a storeroom on the northwest of the first floor. A particularly lofty 15th-century section, 23 feet to the eaves, measures 30 feet by 15 feet, containing two rooms on each floor, with a central stair bay (a newel survives) and a four-light window to the west, formerly lighting a door from the stair. A large first-floor north room is spanned by a chamfered arch-braced collar beam truss to a clasped-purlin roof with arched windbraces. Close-spaced wide wall studs are visible. Another room has a king-strut and collar truss to a clasped-purlin roof with curved windbraces. There is no evidence of original chimneys. Stop-chamfered spine beams with run-out stops are present.
