Barn Almost Adjoining At Rear Of Tregithew Farmhouse

This building is a barn almost adjoining the rear of Tregithew Farmhouse, dating from the 18th and 19th centuries. It features serpentine rubble walls with dressed granite monolith sills, jambs, and lintels. The barn has a steep hipped scantle slate roof with clay ridge tiles. It is a large rectangular structure with two first-floor winnowing bays above what was likely a shippon, which has been used for stabling since the 19th century.

A horse engine house was added to the rear right around the mid to late 19th century, featuring a canted hipped end supported by quarried granite posts. The earth bank at the rear has largely been removed. The barn is two storeys or one storey over a basement. The south front has two first-floor winnowing doorways grouped towards the middle, with an original ground floor doorway to the right. The middle and left-hand doorways, along with two small ground floor windows, are later additions. The left-hand side wall has a blocked full-width first-floor doorway that was originally used for unloading sheaves from wagons. The rear of the barn has two original first-floor doorways that align with those at the front.

Although the horse engine house has lost its machinery, it still retains some of the timber associated with it in the roof space. The interior of the barn is very complete, featuring original floors and closely set pine roof trusses with lapped and pegged collars and pegged apices. This barn is an unusually complete example from the 18th century that was later modernised in the 19th century with the addition of the engine house for threshing machinery powered by horses or oxen.
