Threshing barn at Whitehouse Farm

This is a late 18th-century threshing barn, with 20th-century additions which are not included in the listing. Associated stables and agricultural buildings from the 18th and 19th centuries, having undergone alterations, are also excluded.

The barn is constructed of timber framing, with brick gable ends, a stone and brick plinth, and is clad in weatherboard. It forms part of a group of buildings arranged around a roughly square courtyard, with the barn occupying the northwest range.

The building has a T-shaped plan. It is a high, three-bay structure with a steeply-pitched roof. The timber frame stands on a brick plinth with stone, the height of which varies toward the rear. The long elevations are clad in horizontally-laid weatherboarding above the plinth, with plain clay tiles covering the roof. The south-eastern elevation, facing into the farmyard, features wide double timber doors in the central bay. A small square timber casement window has been inserted in the upper part of the left-hand bay. The gable ends are clad in red brick. A wide, full-height projecting gabled porch with full-width double doors is located at the rear.

The barn’s timber frame is largely intact. The frame consists of close-studded uprights, high midrails, and diagonal bracing. The western bay is divided horizontally by a timber floor supported on brick piers and a central upright timber post. The roof structure features trusses with jowled upright posts, roughly-chamfered tie beams, paired principal rafters, queen struts, a high collar, and two tiers of butt purlins, all pegged together. Diagonal braces extend from the uprights to the tie beams, lapped on but likely original due to the presence of chamfering. The roof retains its original common rafters. The central bay retains its threshing floor, extending into the porch. A new opening has been created in the southwest gable end to provide access to a late 20th-century extension.
