Barn at Upper Cwm Cadarn

Rubble stone, the upper end retaining some external plastering, and slate roof with crested red tiles. Five bays, with a central threshing floor, the uphill end formerly floored and walls plastered, probably a granary, with a blocked door each side to the second bay from the upper end. Pitching doors on the W side, also blocked when the building altered and the floor removed to extend the barn. One high level door to the S end gable, probably the main access. The lower end of the building has 2 tiers of slit vents, but 4 tiers in the gable end, and a central pitching door. The cartway on the NE side has been extended later to form a short porch with a raking roof.

The upper end has a full truss with half-chamfered tie at floor level, the upper part framed for a door between the upper and second bays. Other trusses with tie beam and collar carrying raking struts to the principal rafters. Two tiers of trenched purlins.
