Roskestal Farmhouse, Including Front Garden Walls and Gate-Piers

Roskestal Farmhouse is a farmhouse dating from the 17th century, with extensions added in the 18th century. The front is pebble-dashed, the gable ends are rendered, and the rear wing is of granite rubble with granite dressings. It has scantle slate roofs. The front range exhibits 17th-century dressed granite chimneys with a simple entablature over the gable ends, scrolled granite kneelers, and heightened eaves. The building follows an L-shaped plan. The original front range was a two-room layout, likely with a parlour to the left and a hall to the right, separated by a cross passage that leads to a stair outshut in the rear angle. A 17th- or 18th-century service wing or granary is set at right angles behind the left-hand side, accessed by granite steps leading to its loft. The remains of a wall at the rear right of the wing suggest a formerly enclosed rear courtyard.

The two-storey, nearly symmetrical front has three windows on the south-east elevation, with a central doorway. A chamfered 17th-century doorway and a chamfered three-light mullioned window are on the left-hand side. The other windows are circa late 19th or 20th century horned sashes. The left-hand gable end features two chamfered window openings dating from the 17th century. The rear wing incorporates reused chamfered stones in its right-hand wall, while other original openings are constructed of unchamfered granite monoliths. A chamfered doorway is situated through a high courtyard wall behind the right-hand rear corner of the house. Some reused 17th-century masonry exists within the farm buildings at Roskestal. Low, cement-coped granite rubble walls enclose the rectangular front garden. The gateway, aligned with the front doorway, features round-headed granite monolithic piers. The interior contains a possible late 18th-century stair, alongside 19th- and 20th-century carpentry and joinery, with the possibility of earlier features not currently visible.
