Description

This is an outbuilding located to the east of Pentwyn, constructed from rubble stone and featuring a slate close-eaved roof with a small hip on the eastern gable. The south side has a broad opening on the left, which has likely been enlarged from a single door. The eastern end includes a loft door with a timber lintel, while there is a blocked door in the northern rear wall.

Inside, the building has a lofted space with heavy beams and three stalls against the eastern end wall. The floor is cobbled, and the roof is supported by a triple purlin structure with a pegged tie-beam-and-collar truss.
