Former Farmhouse at Cefn-yr-Own-Uchaf

This is a former farmhouse, likely originating in the medieval period, with significant alterations and additions spanning several centuries. A later, 17th-century byre and cartshed adjoin the farmhouse to the right, recessed slightly. A modern agricultural lean-to abuts the farmhouse to the left. The house was used as a cow-byre and hay loft as recently as 1994.

The main farmhouse is a low, single-story rubble building. It originally comprised five bays, of which two cruck pairs and one cruck blade survive, the central pair having been removed when the large central stack measuring approximately 3.7m x 4.3m was inserted. The collars are also missing. The roof is largely of undulating slate, pitched at a medium to steep angle, though a section to the right is covered with corrugated iron. A later rubble dormer with an iron catslide roof breaks the eaves, and now serves as a loading bay; the walling beneath it has been rebuilt. The original entrance was positioned off-centre to the right and now has a modern concrete lintel. A plain, later entrance stands to the left, featuring a large stone lintel and stable doors. A rectangular unglazed window opening is situated to the right of the primary entrance, with two further windows, now blocked, ascending slightly with the rising ground level. A later entrance to the rear has deeply recessed stable doors. There is a central rear projection with a small, blocked window, and another blocked window to the former parlour section at the right. The left gable end has two square window openings; the ground floor window has a boarded shutter and the upper window has tin sheeting. A modern rubble retaining wall supports the base of the gable, which has a brick-coped gable.

Inside, the central hall retains a large fireplace with a huge chamfered ingle beam and an internal niche. A recess to the right originally led to a stair access within the rear projection, now partly blocked. The ground floor of the hall features a slate and stone floor and a later rubble dividing wall, partly ceiled over. The far right section was a former service bay, with evidence of a partition to the surviving cruck blade; this area is now stepped up and has a tiled floor, with a rubble ledge at the gable end. The left section was the former parlour. It has a blocked fireplace with a chamfered bressumer and a stair access, now inaccessible. Finely stop-chamfered main and subsidiary ceiling beams are present in the left section, while the right section has plain (later) beams. A niche to the gable wall features a large window to the right, with a further blocked window to the rear wall; a later cobbled floor is also present.
