Llewyn-y-Celyn Farmhouse

Llewyn-y-Celyn Farmhouse is a two-storey farmhouse constructed of painted rubble stone, topped with a slate roof that features 20th-century brick chimneystacks, including one off-centre ridge stack and another at the south gable. The front elevation is irregular, with the stone encasing wall of a former medieval hall-house slightly projecting to the right. On the first floor, there is a 3+3 pane casement window, flanked by two square window openings with 2+2 pane casements. The ground floor has an off-centre entrance doorway on the left, featuring a chamfered oak door-frame with a Tudor-arched head and a 20-boarded door. To the left of the entrance is a 2+2 casement window with a stone sill, while to the right, there is a 17th-century 4-light ovolo mullion window with inserted 3+3+3+3 pane casements, along with a smaller 3-light window of similar design.

Attached to the north gable is a 20th-century single-storey brick extension with a gabled roof covered in composition slates and fitted with 20th-century metal windows. The garden elevation is also irregular, featuring walls of painted render. The first floor has three 2+2 pane casements with flat heads and stone sills. The ground floor mirrors this with similar windows on the left and right, and in the center, there are two 2+2 casements with segmentally arched heads and stone sills. The extension to the right includes a small 2-pane window and a larger 2+2+2+2 pane casement.

Inside, the entrance at the former service end has a 20th-century straight stair opposite the entry. Mortices in the headbeam indicate the position of a former cross passage partition, which had doorways at each end leading into small service rooms. To the left of the entry, the gable wall features a Tudor-arched doorway, likely relocated when the cross passage was blocked. On the right side of the entry, a 20th-century boarded door leads into the former hall. The ceiling beams and joists are chamfered with hollow and fillet (Wern-hir) stops. There is a former fireplace stair to the right of a now-blocked 20th-century fireplace. A transverse post and panel partition with a Tudor-arched doorway separates the hall from the parlour, which has a chamfered ceiling beam with straight-cut stops.
