Description
The barn at Whatbarns Farm is a 17th-century structure with an early 19th-century lean-to shelter shed on its west side. It features a timber frame that is weatherboarded and sits on a tarred red brick plinth. The barn has a steeply pitched roof, currently covered with corrugated aluminium. It is a tall, five-bay barn facing east, with a gabled porch on the west side. There are opposed double doors in the middle bay and high pitching doors in the second and fourth bays on the east side. The barn is supported by jowled posts with mid-height rails between them, which are jointed in-line. It has straight braces connecting to the tie-beams, and the roof structure includes queen-strut-and-collar angle-braced trusses with two clasped purlins on each slope. Additionally, there are straight tension braces in the walls. Attached to the west side, to the north of the porch, is a three-bay timber framed shelter shed.
