Cowhouse and Barn Range at Llwyndyrus

The range is built of rubble stonework with a slate roof. It is set on a continuation of the raised boulder-paved platform above the fold yard on the E. The N end consisting of a 4-bay cowhouse wider than the attached barn at the S end. Two entries at the rear (W) of the cowhouse. The barn is narrower, of 3 bays, with a central wide opening each side, and flanking tall ventilation slits. A long lean-to is attached at the rear at the S end.

The four bays of the cowhouse are expressed by three king post trusses with shoulded kingposts carrying raking struts to the principal rafters. Three tiers of purlins. Slate two-beast stalls for cattle facing across the building, formed with slate slabs, protected around their edges by timber, and a feed walk along the back against the wall.
