Barn and Farmbuilding Range, 40 Metres North East of Byer's Garth Farmhouse

The barn and adjoining farmbuilding range, located 40 metres northeast of Byer's Garth Farmhouse, is a Grade II listed structure. This building complex consists of a much-altered barn, likely from the mid-17th century, and an early 19th-century west range. The barn is constructed from squared coursed sandstone and features a roof made of pantiles, Welsh slates, and corrugated-asbestos sheets. The west range is also made of squared stone with brick dressings and has a slate roof. The layout is L-shaped, with the barn and the 19th-century range at right angles to each other.

The barn is tall and single-storey, originally consisting of seven bays, with an additional bay added on the west side. It has been altered with 20th-century openings and features blocked opposing doors near the centre. There are two rows of scattered, blocked triangular vent holes on both the front and rear. The roof is steeply pitched with swept eaves. The two-storey, five-bay west range has brick quoins and partly-blocked elliptical brick archways on the ground floor facing the yard, along with a keyed-oculus pitching eye on the west face. This range has a low-pitched hipped roof.

Inside the barn, there are six original adzed roof trusses made of heavy scantling, featuring cambered tie beams and curved Queen posts that support high collars. Some original purlins remain, along with later intermediate trusses and cross bracing. The west range is included for its group value, while an altered parallel east range is not considered of special interest. Despite the alterations, the barn is a rare 17th-century survival that retains a largely original roof structure.
