Description
The East range of farm buildings at Tan-y-bwlch is a 19th-century structure located within a farmyard that measures approximately 40 meters square. This range includes long buildings on the east, north, and west sides, with an open cartshed partially enclosing the south side.
From right to left, the east range features a store with a granary above, which has a gabled loft door. Next is a three-bay barn, followed by a narrower three-bay workshop designed for shafting, and at the northern end, there is a four-bay cowhouse that opens internally at the corner to the cowhouse range along the north side. The barn is equipped with full-height doors leading to the central winnowing floor, as well as ventilation slits on each side. The workshop section includes a stable door and two ground floor windows, along with windows in the loft area. The cowhouse has two similar doors and square ventilation windows, with one bay currently functioning as a workshop.
Architecturally, the barn features two shouldered king strut trusses with angled struts, which support the principals and two tiers of purlins. The concrete walls of the building are left exposed on both the interior and exterior.
