Barn About 70 Metres South of Alston Farmhouse, Adjoining Alston Cottage

This building is a former threshing barn, later used as a poundhouse, and now serves as a garage and store. It is located about 70 meters south of Alston Farmhouse, next to Alston Cottage, which is an unlisted late 19th-century building. The barn likely dates back to the early 16th century and is constructed of stone rubble with a significant area of cob, which was probably the original material for the entire structure, located at the left end of the front wall. The roof is covered with corrugated iron.

The barn is a small oblong shape with two opposing doors placed centrally: a wide front door and a narrow rear door, the latter of which is now blocked. To the right of the front is a second cart entrance. It is a single storey building. The front entrance to the former threshing floor features a chamfered, shouldered-head wood door frame with a cranked lintel, while the rear door frame is square-headed with pegged joints. The door frame to the right is made of later, reused timbers.

Inside, the barn has late 20th-century roof timbers resting on a concrete ring-beam, likely added in the 1970s. Barns with early door frames are rare in Devon, making this a particularly well-preserved example. It is noted that the barn was once used as a poundhouse for cider, and the field behind it was referred to as Poundhouse Orchard on the 1840 tithe map.
