Outbuilding at Mynydd Brith

Outbuilding, rubble stone with corrugated iron roof, built in 2 parts with straight joint between, downhill site with older part apparently at the uphill end. Downhill end appears to have been a lofted coach-house or cartshed with 2 blocked broad entries to ground floor with stone voussoirs to cambered-arched heads and to 2 arched loft windows. Blocked door at mid-height to left was probably the original loft door reached by outside steps. Tall right end wall has 7 tiers of dove-openings in gable. Plainer older section to left has three doors with stone voussoirs and date plaque to right 'ID 1830'. Left end gable has loft opening with timber lintel. Rear wall right is of almost mortarless stone.

Plain barn interior with later C19 pine trusses to roof. Four blocked ventilation slots on back wall.
