Yarnacott, Including Barn Attached to West End

Yarnacott is a farmhouse with an attached barn, likely built in the early 16th century and remodeled in the 17th century, with the barn added in the 18th century. At the time of the survey in 1985, the farmhouse was undergoing alterations. The farmhouse is constructed of roughcast rendered stone and cob, topped with an asbestos slate roof that is half-hipped at the right end. It features a lateral hall stack with offsets. The barn is made of unrendered cob with brick dressings and has a corrugated asbestos roof.

The farmhouse has a three-room and cross-passage layout, with stairs located in the cross-passage. The extended lower end may have originally served as a shippon before being divided into two rooms, with the cob partition later removed. The building is two stories tall and has a four-window range. On the left side, there are two 19th-century casements with eight panes per light, and to the right of a six-panelled door leading to the lower end, there is a similar casement. A slated canopy extends over the bread oven projection at the hall stack and the cross-passage doorway to the left, which has a six-panelled door. There is also a 19th-century two-light hall casement with nine panes per light and a small four-paned single light window at the dairy end. The barn features a loft door above three plank doors.

Inside the farmhouse, there are stop-chamfered ceiling beams and bressumers at each end of the hall, with a chamfered beam in part of the lower end. The lower end has two raised cruck trusses with threaded purlins; the inner truss has mortices on the soffits of the blades for a removed collar, while the truss towards the gable end previously had lap-jointed collars. A roughly hewn pegged truss, possibly from the early 19th century, is located over the hall, and the remaining trusses were replaced in the 20th century. However, a section of the ridge piece and ridge support shows signs of smoke-blackening, indicating that this building may have originally been an open hall house, with the lower end likely always having been floored over, as both cruck trusses are clean.
