Farm building at Pen-y-waun farm

This is an early 19th century, two-storey farm building with a design that suggests it may have originally served as bothies for farm labourers, featuring separate entrances for the ground and first floors. The structure is made of rubble stone and has a hipped slate roof with wide eaves and stone chimney stacks at each end.

On the north side, which faces away from the farmhouse, there is a central four-panelled door surrounded by panelled reveals and flanked by tall 12-pane sash windows. Notably, this side lacks windows on the first floor. The elevation that faces the farmhouse has a central door but no ground floor windows. However, the first floor features a central 12-pane sash window, originally flanked by two tall round-headed windows; the left window is now blocked, while the right window, which has a moulded architrave, has been converted into a doorway with a long ramp of 15 steps leading down to the farmyard wall. There is also a similar blocked tall round-headed window on the east end and another 12-pane sash window on the west end. Internally, the upper floor is currently used as a corn store.
