Description

The Ironstone Barn at Forest Side Farm is a late 17th-century threshing barn, with a midstrey likely added in the mid 18th century. This aisled timber barn consists of four bays, featuring outer walls made of coursed ironstone, with some visible ironstone galleting on the southeast front. The barn has mainly brick dressings, with stone and brick quoins on the southwest, including some narrow Tudor bricks. It has a steeply pitched hipped roof, which was probably originally thatched but is now covered in corrugated iron.

On the exterior, there is an off-central cart entrance with a hipped midstrey supported by brackets on the northwest side. These brackets rest on posts that have an 18th-century cut profile, and there are large plank double doors on pintle hinges. The northwest front includes six ventilation slits and a 19th-century fixed casement window. The northeast side features two similar fixed casements, one ventilation slit, and a wide doorcase with a plank door on pintle hinges. The southeast side has a fixed casement and two wide doors, one equipped with an iron latch and pintle hinges, along with two ironstone triangular buttresses. The southwest side contains two ventilation slits edged in stone and a wide brick-edged door opening.

Inside, the barn is aisled on both sides with outshuts at each end. The aisle posts are jowled and have curved or diagonal tension braces. Three bays feature queenposts, while one bay has an angled queenpost. The rafters are pegged with clasped purlins. On one side of the threshing floor, a weatherboarded threshing board remains. Historically, the original farmhouse, Temple Down, which had a thatched roof, was destroyed by fire in 1861.
