Barn and Cider House at The Maerdy

The barn and cider house at The Maerdy date from the 18th century and form a linear range. The southeast wall of the barn is made of brick up to about 2 meters high, with timber framing above. The brickwork of the barn does not show a recognizable bond, while the cider house features English garden bond brickwork. Both buildings have roofs covered in corrugated metal.

On the southeast front, the barn is on the left and the cider house is on the right. The barn has a projecting gabled porch at the center of the threshing floor, with the gable head clad in corrugated metal. There are boarded double doors to the barn, along with two half-doors to the right. To the left of the porch is a single-storey lean-to shelter shed with a corrugated roof. To the right of the porch is a lofted cowhouse that has a projecting pentice with a corrugated roof and three ground-floor doorways from left to right: an old doorway that is blocked by horizontal slats, followed by two boarded doors with vent slits. The upper timber-framed walls flanking each side of the porch are weatherboarded.

Attached to the southwest gable of the barn is a small single-storey gabled extension with a pantile roof, which is flanked by 20th-century corrugated metal sheds. The southeast front of the single-storey cider house features a segmental arched window opening, a doorway with a brick skewback lintel, and another doorway with a timber lintel on the far right. On the northwest elevation, no barn doors remain. To the left of the threshing floor, there are two square window openings and a doorway leading to the lofted cowhouse at the lower end. The back wall of the cider house on the left is made of rubble stone and has an off-centre boarded door, flanked by square unglazed window openings on each side. The northeast end wall projects beyond the gable head and has a small hipped roof with a window opening below.

The barn has five bays, collar and tie beam trusses, and two tiers of purlins.
