Description

Lone Barn Farm Barn is an early 18th-century timber-framed barn, with its exterior covered in weatherboarding resting on a brick plinth and topped with a half-hipped thatched roof. The barn features a cart entrance in the second bay, with casement windows above and plank garage doors below. The east elevation displays some old wide tarred weatherboarding, while the west elevation has a plank door. This four-bay barn is aisled to the south, with jowled posts that primarily exhibit an 18th-century cut profile, although the northeast corner post may be a reused element. The roof structure includes angled queen struts with a collar beam, lacking a ridge piece, and has two tiers of clasped purlins supported by diagonal wind braces. The aisle roof features staggered purlins and diagonal wind braces as well. Additionally, some timbers within the structure are reused, and part of the north wall incorporates an early 19th-century brick wall constructed in Sussex bond.
