Farm Building at Llwyn Offa Farm

This is a long farm building dating from the 18th century, situated on a sloping site. It is constructed of rubble sandstone with squared quoins, and has an undulating slate roof. The building is orientated north-south. The uphill (north) end features a high coped gable and a large three-light timber window with a timber lintel, set above two ventilation slits infilled with pipes. The east side has a single doorway flanked by ventilation slits (two to the left and one to the right, all infilled with pipes). A raised door, formerly leading to a threshing floor and accessed by stone steps, is positioned to the left, with stable doors and a square loft hatch beyond. Further to the left is a three-light stone mullioned window, followed by a planked door. A 20th-century unit has been added to the south end, with an external staircase providing access to an upper-level doorway and a stable doorway to the far left. The south gable is coped with kneelers. The west side features a 20th-century brick lean-to with two planked doors, flanked by ventilation slits, and a long blockwork lean-to with stable doors. A loft hatch opens over a flat-roofed addition at the right end.

Inside, the roof structure incorporates pegged tie-beam trusses with raked struts and trenched purlins. The floors are mainly brick-paved, and the cross-walls are timber-framed with brick infill set on stone plinths. The northern unit was likely used for storing or drying corn and has four ventilation slits to the west side, two to the north, and two to the east, all with wide splayed reveals and timber lintels. A central passage and threshing floor are present in a smaller unit to the left, with mid-20th century alterations including a concrete floor, plastered walls, and a ceiled roof. A narrow stable is situated to the left of this, followed by a byre with former stalls set at right angles. This byre contains a large, chamfered cross-beam with ornate stops, likely inserted later. The south wall appears to be the original end wall of the building, with a further unit added to the south end. This wall contains a square recess with a stone sill, and another recess is present on the west wall. A loose box has been added to the west side. At hay loft level, the original end wall contains a pegged timber door surround with a segmental arched head, which appears to be a reused feature. Projecting stonework, resembling a former chimney breast, is visible from the south side. The south unit was originally a stable.
