Barn at Llwyn-celyn Farm

The barn at Llwyn-celyn Farm is a 19th-century structure built from red sandstone rubble and topped with a corrugated sheet metal roof. Unlike typical threshing barns, it lacks opposed doors and has always included an upper floor, suggesting it may have served as an early combination cowhouse and hayloft. The barn is set into a bank and features a taking-in door in the gable end.

The front elevation includes central doors beneath a timber lintel, with a lower cowhouse to the right, obscured by a corrugated metal lean-to. To the left of the doors is a large raking buttress, and further left is an inserted double door under a timber lintel, which may have compromised the structure's integrity. The lower gable is open at the apex, while the rear wall is plain and featureless.

Internally, the barn has four bays, with the ground floor divided by modern partitioning. The hayloft retains a roof supported by three principal trusses, two tiers of trenched purlins, and a ridge piece, all of which appear to be original, along with the secondary rafters.
