Description
The barn and cowhouse at Pwllyrhwaid Farm is a 19th-century agricultural building constructed from local rubblestone that has been whitened, topped with stone slate roofs. The structure features a large threshing barn with a granary attached in line and a cowhouse built at a right angle to one end of the barn. There is a later lean-to shed on the gable end of the barn.
The threshing barn is notable for its paired central openings and three tall slit vents on either side. The roof is plain and slightly raised over the doorway. To the right, there are steps leading up to a gabled granary door, followed by a window that likely leads into a stable with a hayloft above, although this stable is accessed from the rear. The right gable wall includes a door for the hayloft.
On the left gable, there is a lean-to shed with a corrugated iron roof, featuring a four-slit vent above and an owl hole at the apex. The rear of the building has an integral cowhouse wing with four original doorways and a hayloft that has four rooflights above.
During a recent survey, only the interior of the barn was examined. The layout indicates that the cowhouse is an integral part of the structure, while the granary is an extension, as evidenced by the two tiers of slit vents and an owl hole in the gable wall. This suggests that a hayloft existed at the end of the barn prior to the construction of the granary. The barn features a five-bay principal rafter roof with collars and ties, along with two tiers of trenched purlins and secondary rafters, all of which are intact.
