Two Barns, Horse Engine House, Pigsties, Cowhouse, Linhay and Former Cowhouse with Vehicle Entrance Flanking Road to North-West of Pentreheylin Hall

A group of farm buildings including two barns, a horse engine house, pigsties, a cowhouse, a linhay, and a former cowhouse with a vehicle entrance, dating from the mid-18th century to the mid-19th century, with later alterations. The barns and cowhouse are constructed of red brick, with one barn incorporating a weatherboarded timber frame. The former cowhouse flanking the road and the horse engine house are of uncoursed limestone rubble, and the linhay has corrugated iron cladding on its south side. All buildings have slate or corrugated iron roofs. These buildings form a farmyard associated with Pentreheylin Hall, with the former cowhouse and vehicle entrance situated to flank the road.

The first barn and lower cowhouse are aligned north-east to south-west, with a second barn attached at a right angle to the south-east. The horse engine house, with adjoining pigsties, is situated in the angle between these two barns. The linhay is attached to the north-west end of the second barn, with a former cowhouse at a right angle to the south-west at its north end, adjoining the road, with a vehicle entrance to the south-west.

The barn and lower cowhouse are two-storied and feature X-shaped air vents flanking a lozenge-shaped vent, with a boarded door approached by external steps. A segmental-headed doorway is flanked by infilled square-headed openings with wooden lintels and inserted 20th-century windows. The cowhouse has eaves hatches alternating with lozenge-shaped air vents, and a four-bay opening with a continuous wooden lintel, and inserted doorways on the ground floor. A polygonal horse engine house is open on the east side, with attached pigsties. The second barn has lozenge and X-shaped air vents and a segmental-headed opening on the first floor of its south-east gable end. The linhay has seven open bays, divided by cast-iron columns, and two hatches above. The former cowhouse is open to its north-east gable end and has a vehicle entrance arch to the opposite end, with an eaves hatch to the left of centre.

The interior of the barn attached to the lower cowhouse has a queen-strut roof in five bays, with jowled wall posts and curved principals on the first truss from the south-west, and a continuous loft. The cowhouse has a king-post roof in six bays. The horse engine house also features a king-post truss. The second barn, open to the roof in four bays, has a mix of king-post and queen-post trusses, along with collar and tie beam trusses to the north-west gable end, incorporating timber-framed square and rectangular panels and tension braces. The linhay and the former cowhouse adjoining the road both have king-post roofs.
