Gorllwynuchaf

Gorllwynuchaf is a 17th century building constructed from rubble stonework that encloses a cruck-framed structure, topped with a slate roof featuring rooflights and raised coped gables, likely replacing the original heather thatch. The building is one storey and attic high, with three bays, a large external chimney stack, and a narrower outbuilding at one end. A boarded door leads into the central bay, which has a corresponding back door. The small windows are deeply set and fitted with modern frames and glazing. In the 19th century, a water wheel was installed at the rear of the upper bay to provide power for domestic use, with a launder running across the back of the house above the doorhead level. An in-line outbuilding is attached at the upper end.

Inside, the structure features two complete cruck trusses that are halved and pegged at the apex, along with a tenoned and pegged collar beam and tie. The principal rafters are positioned on the back of the crucks. The tie beams that support the wall plates are lower than the current walls, indicating that the external walls have been raised or rebuilt in stone. Some original rafters are pegged to the purlin. The left bay, now serving as the living room, is open to the roof and displays exposed purlins and rafters, with one purlin showing a scarf joint at the end, possibly indicating a lost third bay. The central bay contains the entrance and the 19th to 20th century staircase, separated from the upper bay by a post and panel partition. The upper rail shows signs of three original doorways leading into a subdivided upper bay. A rear door is located next to the staircase. The upper bay, which houses the kitchen, features a tie beam at the gable end, providing further evidence of the building's original timber frame. It has a single tier of heavy square purlins without windbraces, and the floors are made of 19th century stone flags. The gable end fireplace is notable for its high chamfered lintel.
