Barn at Treveddw Farm

The barn at Treveddw Farm is a Grade II listed building constructed from grey sandstone rubble with a roof made of corrugated metal sheeting. The barn is situated at the downhill end on the left side of the road elevation. It features central opposed cart doors and a small porch, with two vertical slit vents on either side and a small cowhouse door located under the lower end. To the right, there is a well-built outside staircase leading up to the granary, which has a taking-in door beneath a projecting gabled porch over an open cart shed, along with a door from the stairs on one side. The end bay includes another open cart shed with a taking-in door above.

The gable end of the barn has three doors for cows and a central feeding passage, although one of the doors is blocked. Above, there are two tiers of slit vents for the hay tallet. The rear elevation features a modern projecting extension in front of the higher end. The rear of the barn mirrors the front, but the porch retains a stone tile roof.

This seven-bay structure is divided into two parts: a five-bay threshing barn with a cowhouse under the lower end and a two-bay granary. Inside the barn, there are four principal rafter trusses with collars and ties, a stone dividing wall, and an additional truss in the granary. The barn also has raking struts, four tiers of trenched purlins, a ridge piece, secondary rafters, and battens, all of which are intact except for the covering. The lower cowhouse features heavy roof beams and a manger, while the granary floor is situated above two cart sheds.
