Barn, Mantley House

The barn at Mantley House is a Grade II listed structure dating from the 16th century, with a left extension added in 1774, as indicated by a datestone. It features a timber frame set on a stone plinth, with a façade of corrugated iron facing the road and weatherboarding on the rear. The barn has a corrugated iron roof, while the left extension has a tiled roof. The left gable of the extension is made of flat stone with larger quoins.

On the road side, the barn is slightly set forward and has double boarded doors, with one bay that is double opening. Originally fully doored, the top half is now open. There is a single bay opening for the cartshed that is slightly set back, featuring a flat head and corrugated iron above, along with a square opening that originally had a shutter on the left. The right return has a stone ground floor with corrugated iron above. A weathervane is located on the left gable of the barn, which also has plain bargeboards.

The left return of the barn's left extension includes two small slit air vents at the bottom, a square shuttered pitch hole above, a quatrefoil air vent, and the date stone in the gable. Inside the barn, the framing is three or four panels high, with curved braces connecting to the sill. Curved braces from the main posts to the tie beams are visible in two trusses, along with angle strut trusses and one pair of purlins, but there is no ridge. The interior of the left extension has not been inspected. This barn forms an unusually complete group with the house and cowhouse nearby.
