House and Barn at Pen-yr-wyrlod

Pen-yr-wyrlod is a one-and-a-half storey former house with an attached barn, set into a slope. The building features battered walls made of rubble sandstone, with traces of limewash, and has a steeply-pitched slate roof topped with a central stone stack. The house is located at the uphill end and includes a wide boarded door on the left, which is sheltered by an added gabled canopy. To the right of the door is a former sash window, and at the right end, there is a former casement window. Above the main entrance, there is a single raking dormer. At the lower end of the building, there is a central wagon bay doorway with double boarded doors, and to the right of this doorway, external stone stairs lead to a loft doorway located to the left of the stack. The left end features a byre door with a timber surround and a ventilation slit above it. An added projection at the lower end is constructed of random rubble and has a corrugated metal roof. The right gable end of the house has an attic opening located to the left of centre, supported by timber stanchions.

At the rear, there is a cross-passage doorway with a 17th-century window to the left. The barn includes ventilation slits and an owl hole.

Inside, entry is directly into the hall, where the fireplace has stop-chamfered jambs and a timber bressumer that features an unusual integral moulded mantel shelf. The hall has chamfered cross beams. The fireplace stair has been removed, and the space has been converted into a bread oven. A post-and-panel partition in the hall retains a 4-centred door head with its original door. The service rooms are separated by another partition that has an ovolo-moulded 17th-century door head, which may be a reused element. Additionally, part of an early door head is also reused in the rear door. The house has a three-bay post-and-pad roof, while the barn features a similar three-bay collared roof.
