Birkhill Farmhouse and attached farmbuildings to South

Birkhill Farmhouse is a mid-18th century farmhouse with attached farmbuildings, arranged around three sides of a farmyard. The farmhouse is largely of brick in an English garden wall bond, with sandstone dressings, and has a Welsh slate roof. The farmbuildings are of brick and some coursed sandstone rubble, with green slate and corrugated asbestos roofs.

The farmhouse has a symmetrical five-window front with chamfered quoining and a plain cornice. All windows have plain surrounds, cornices to the ground floor, and eight-pane sashes, except for two renewed casements. The central doorway has a cyma surround and pulvinated frieze, and a half-panelled/half-glazed door. A sandstone, slated lean-to is located at the extreme right, and the lower service area to the right has no windows. End stacks are present, with the left-hand stack original and having stone coping to the left only.

The rear of the farmhouse features a sixteen-pane sash window to the kitchen, as well as two first-floor windows (one a sash) and a small window lighting the stairs. Above the doorway, which has a rectangular overlight, is a small plaque in a chamfered surround bearing the letters 'P.H.H' (Howard) with a relief lion. Inside, the kitchen has a flag floor, and the first-floor fireplace surround has curved angles. Features include one panelled door and some original floorboards.

A stable range is attached to the south, with a side purlin roof, slit ventilators, original openings, and a 20th-century garage doorway. A south range incorporates a threshing barn, originally attached and heightened in the 19th century, featuring slit ventilators and an A-frame roof with collars and staggered purlins. A granary is also attached.
