Barn and cart shed to Byram Farmhouse 12 metres to north east of house

The building is a barn and cart shed located 12 meters to the northeast of Byram Farmhouse, dating from the late 18th century and designed by John Carr. The structure is primarily made of partly-rendered magnesian limestone coarsed rubble with ashlar dressings. It features a corrugated-iron roof with two levels for the barn and a Welsh slate roof for the cart shed, topped with a cast-iron weathervane.

The barn is a multi-bay structure, with eight bays to the south serving as the hay barn and the remaining bays forming the threshing barn, while a six-bay cart shed is situated at the northeast corner. The two southernmost bays of the barn are blocked. The ninth bay has a slightly wider and lower segmental arch, which likely originally provided access to a yard beyond, while the other arches are round. The arcade to the north is blocked with slit vents, and the piers supporting the arches have square capitals. The eaves are cogged brick, and the weathervane, shaped like a cow, is positioned above the ninth bay. The cart shed features a hipped roof.
