Blaen-Cwm-Llawenog

Blaen-Cwm-Llawenog is a long, one-and-a-half-storey building, likely dating to the 18th century. It appears to have started as a three-unit dwelling on the left, with a single unit added to the right, possibly as a separate dwelling. A further agricultural range was added to the left end, presumably contemporary with the conversion of the end bay of the house for agricultural use. The exterior is finished with roughcast render over stone, with the stone exposed in the left-hand bay, and has a slate roof. A projecting stack stands at the north end with a yellow brick shaft, while a roughcast stack is located to the left of the centre. The original entrance is directly in front of the central stack, creating a lobby-entry plan. A boarded doorway is asymmetrically flanked by three-light casement windows with cast-iron glazing bars and segmentally arched heads. A similar window is to the right of the entrance in the right-hand bay, which has a boarded door with a small over-light. Four gabled dormers are visible on the upper storey, with a segmental brick head extending into the left-hand agricultural bay. A lean-to structure at the rear was formerly a dairy.

The original house comprises two rooms on either side of a large stone chimney, with a further former domestic unit to the left, and a possible separate dwelling added to the right. The building has a lobby-entry plan. The two original rooms each contain fireplaces with roughly arched and chamfered bressumers; the left-hand fireplace includes an integral bread-oven. Both rooms have longitudinal beams featuring distinctive deep chamfers with scrolled stops. In the right-hand room, mortices indicating the presence of an earlier, lower ceiling remain, with the existing joists likely the result of 19th-century remodelling work. A doorway with a shaped head leads into the left-hand room, which retains some original stop-chamfered joists to the rear of the main beam. A similar beam survives in the adjacent room, suggesting that it was once part of the dwelling. The right-hand unit also has a stop-chamfered longitudinal beam, but its position towards the rear of the room suggests it may not be original.

On the upper floor, timber-framed trusses and partitions survive between the two left-hand units and immediately to the right of the stack. One partition has a rail below a tie-beam, which has been cut for a doorway. Above the tie-beam is a collar with struts and a second collar. The underside of the rail is morticed for posts, indicating a timber-framed wall pre-dating the present stone wall. Several elements of the trusses appear to have been reused, including a chamfered ceiling beam and the head or sill of mullioned windows. A similar truss adjacent to the chimney also has a rail with braces to the tie-beam and posts to the collar.
