Farm Building at South-West End of South Harton Farmyard

The farm building at the south-west end of South Harton Farmyard is a structure set into the hillside, resembling a bank barn, and dates from the 18th or 19th century. It is constructed from granite rubble and features a hipped roof made of corrugated iron. The building has two storeys, with the ground storey facing the yard featuring a wide central doorway that has a segmental arch, well-cut voussoirs, and a raised keystone. Inside the doorway, there is an open-fronted lobby with three doorways leading off it; two of these have plank doors with wrought iron hinges, while the third door, which leads to the dairy on the left, has thick wide planks alternating with recessed narrow ones. To the left of the outer arch, there is a two-light wood-mullioned window that provides light to the dairy. The second storey has no windows except for a segmental-headed owl hole.

Internally, the building has an upper floor supported by heavy granite lintels, which are set at a higher level over the lobby. The dairy, located in the left-hand ground storey room, features a granite trough along the gable wall, which is supported by granite posts. This trough is fed by spring water entering through a pipe at the upper end and empties out through the lower wall into an external granite trough, from which the water drains to a reservoir located under the north-east range of farm buildings. The roof was rebuilt in the 20th century. This building is part of a well-preserved farmyard layout that includes two other listed buildings and a manure pit.
