Multi-purpose Farm Building at Llwynmawr Farm

This is a four-bay multi-purpose farm building, likely dating from the 18th century, with a rear wing projecting to the northwest. It is constructed of rubble stone, with some weatherboarding under a slate roof. The building’s layout includes a feeding passage containing a threshing floor, which is offset to the left; a doorway to the feeding passage is approached by two steps and has split doors. The barn section to the left has two tiers of ventilation slits. To the right of the threshing doorway, the upper portion is weather-boarded over box-framing, featuring two loft hatches. A doorway with split doors opens into a cowhouse; both these doorways have some brick repairs to the jambs. A butt joint identifies an added bay to the right, with replaced weather-boarding over box-framing in the upper portion and a doorway below to the far right. The south gable end is asymmetrical, featuring vertical timber boarding and a loft hatch, with two ventilation slits below. A small hatch near the base of the wall has a stone lintel, and a blocked one may exist to its right. The rear elevation has a small raised doorway to the threshing floor and two tiers of ventilation slits to the right. The rear wing has a doorway to the south side and weather-boarding to the west gable, along with ventilation slits; a later catslide roof slopes to the north. The north gable of the main range is weather-boarded, with a lean-to extension beneath. The lean-to has a brick end and stone sides under a corrugated asbestos-cement roof, and its north end features two metal windows with ventilators and split doors to the east side.

Inside, the wide threshing passage has a slate floor and low stone side walls supporting pegged timber framing, with surviving posts and diagonal struts. Tie beam trusses incorporate diagonal struts, and there are two rows of purlins to the east and three rows to the west. An opening from the threshing floor leads into the barn to the left, while a low doorway towards the rear leads to the right into the byre, which has lofts above. The byre extends into the rear wing and incorporates timber-framed and wood-planked stall partitions, along with feeding troughs and mangers. A door on the exterior right leads into a feeding passage, formed when the lean-to was added to the north end, which includes concrete and steel stall partitions. An inserted red brick wall is on the left side of the feeding passage, with two doorways. The loft above is partly supported on chamfered beams.
