Pant Mawr with attached outbuilding and barn

Pant Mawr is a farmhouse with an attached outbuilding and barn, designed in an L-shape. It is constructed from whitewashed rubble stone and features slate roofs with roughcast end stacks. The roofs of the house have overhangs at the gable verges, likely indicating a reroofing that took place in the late 19th century. The house has a two-storey front with three windows, which is offset to the right. The windows are 4-pane cambered-headed sashes, and there is a 20th-century door. The front also includes stone voussoirs and stone sills, with slate-hanging on the left end wall.

To the left, the lower outbuilding range has one 20th-century window, and the roof extends over a full-height opening that connects to the barn at a right angle. The barn features two loops on the right side, a door with stone voussoirs, and one loop on the left side. Additionally, there is a whitewashed rubble lean-to on the end wall of the barn. The rear wall of the barn has a blocked lower door with stone voussoirs, one loop on the right, and two loops on the left.
