Blaen-y-Cwm

An L-shaped farmhouse of 1½ storeys in local quasi-dressed slate masonry, apart from the south gable which has been rebuilt in brick (with loss of chimney); roof of small slates. Stone end-chimney at east. The house is entered at the east side of the south wing: door to right, small-pane sash window to left, two through-eaves stone dormers of unequal height, in one of which a small-pane sash window survives; the dormers not aligned with the window and doorway below. The adjacent south elevation of the contour-range has a window below and a similar dormer above, not aligned. Former door and two windows at rear.

Small stone-walled front enclosure.

The main east/west range has two rooms separated by timber-framed partition. There are two cruck frames in the room to east and intersecting chamfered beams forming 4 squares with chamfered joists counterchanging direction. Large fireplace to east with stone staircase recessed into the wall at the right of the hearth.

In the wing extending south there is a large moulded transverse beam supporting two ovolo-moulded longitudinal beams with unchamfered joists. C19 wooden staircase.

On first floor in the south wing is a timber-framed partition (over the heavy transverse beam); C19 partitioning.
