Barn and Attached Outbuildings Approximately 15 Metres East of Caswell House and Caswell Farmhouse

This building is a barn and attached outbuildings, located approximately 15 meters east of Caswell House and Caswell Farmhouse. The barn likely dates from the 17th century and was re-roofed in the late 18th or early 19th century. It is constructed from coursed limestone rubble and features a gabled stone slate roof. The barn has a five-bay plan with a central threshing floor and a timber lintel over the central double doors.

Inside, there is a collar-truss roof with butt purlins. Attached to the left is an early 19th-century L-shaped loosebox range made from similar materials. To the right, there are early 19th-century covered cart-loading bays, consisting of six bays with stone piers on the right side and a hipped Welsh slate roof. There is also a plank loft door in the barn for unloading sheaves of corn.

At the rear, there is a long outbuilding that served as former stables, a cowhouse, and a granary, mainly dating from the 17th century but with earlier origins. The left side wall features timber lintels over three 17th-century plank doors with Norfolk latches and strap hinges, along with another similar door set in a chamfered stone architrave, a 17th-century chamfered stone light, and four 19th-century hit-and-miss ventilators. Stone steps lead to the granary door.

Inside the cowhouse at the front, there are ogee-stopped chamfered beams and a cobbled floor. The granary above has a four-bay through-purlin roof, with two collar trusses and two upper crucks featuring arch-braced collars and a saddled apex. The cowhouse behind is open to a four-bay collar-truss roof with through purlins. There is a similar roof in the hayloft over the stables at the rear, which have a cobbled floor and oak mangers and stalls. This farmbuilding is a rare and important survival.
