Bank Farm Barn approximately 60m north-west of Bank Farm

Bank Farm Barn, approximately 60 metres north-west of Bank Farm, is a large timber-framed structure, originally dating back to the medieval period. It has undergone significant alteration and extensions over time. The barn is built on a stone plinth. The exterior walls have been re-clad with timber boards and weatherboarding, although some of the boarding has been lost. The roof is covered with corrugated metal sheeting. A single-storey extension of uncoursed stone rubble, also with a corrugated metal sheet roof, has been added to the south end, and a modern bay with timber framing and corrugated metal sheeting occupies the north end.

The building has a rectangular plan, running north-west to south-east, and comprises four bays. Originally, the building was planned as a hall house with a byre in the first bay (north end), a cross passage in the second bay, an open hall in the third bay, and a solar in the fourth bay (south end). A single-storey extension has been added to the south end and the modern bay to the north.

Significant portions of the original timber frame remain, including many of the original pegged timber uprights. Later timber boards clad the walls. Loss of original fabric has occurred, particularly to the west elevations of bays two and four. Evidence of original window and door openings is visible through mortises in the timber frame. The east elevation is situated behind a later cattle shed. The ground level on the east side is lower, exposing a large wall plinth of stone rubble. Stone steps and partial stone door jambs lead up to bay two, indicating the original entrance to the cross passage. The north end retains parts of the original timber framing, now obscured by the modern extension.

The roof carpentry features five crucks, most of which survive wholly or partially. The majority of the trusses comprise a pair of cruck-blades with a high collar, a central post, and a supporting rail. The truss between bays two and three is an exception, featuring chamfered cruck-blades and a high collar. This truss originally had a decorative apex – a central quatrefoil flanked by trefoils, created with vee struts and cusping – but one vee strut has been removed, leaving the decoration only partially intact. Pegged purlins and wall plates form the rest of the roof structure. Smoke blackening on the principal truss and ridge vents indicates the former presence of an open hearth in the hall. Bays two, three, and four are open to the roof, with partial brick infill at the base of some trusses. Bay one has an inserted first floor and doorways with plank doors at the base of the trusses, representing later additions.
