L-Plan outbuildings to rear of Penlan Fawr P.H.

The L-plan outbuildings located at the rear of Penlan Fawr Public House consist of a single-storey former barn dating from the 17th or 18th century. This barn is constructed of rubble, with part of it whitewashed, and features a stepped gable at the right end. It has a slate roof that includes a gabled dormer to the right of the entrance, which now has a modern door. There is one sash window and a fixed glazed window on the gable end, along with six-pane sash windows at the rear. Inside, the barn has been lofted and features a four-bay A-frame roof with chamfered collars and lapped purlins. There is a blocked window at the left end where it adjoins later stables, as well as a blocked doorway that once led to the stable loft.

Adjacent to the barn, at right angles, is a low stable building from the 19th century, which was formerly lofted. This stable is also made of whitewashed rubble and has a slate roof, with a swept roof over the loft door above the main entrance. It features a three-bay roof supported by metal pegged trusses.
