Cwmyrychen

Cwmyrychen is a 2½-storey house built with whitened rubble-stone walls, a slate roof, and stone end stacks. The openings are offset to the right side. The entrance features a half-glazed door within an added half-glazed porch, flanked by stone segmental-headed small-pane cross windows. The upper storey has three iron-framed windows beneath the eaves. The left gable end includes a stone mounting block, while the right gable end has a segmental-headed window in the upper right, which incorporates an iron-framed casement. The rear of the house has added skylights and a 19th-century outshut. On the left side of the outshut is a replacement two-light window set in an earlier stone segmental-headed opening, and on the right side is a pivoting porthole window on the lower storey, with a two-light window above it.

The house features a double-depth plan with a central stair hall that retains full-height timber-framed partitions, showcasing numerous well-preserved carpenters' marks. The open-well stair has newels that are rectangular in section. To the left of the entrance, there is a room with a large fireplace that has a segmental timber lintel. Part of the original timber-framed partition between the main room and two rear service rooms has survived. To the right of the entrance, the room contains a spine beam with ogee stops. The partition between this room and the dairy behind it remains, but access is through a boarded door in the stair hall. The dairy features 19th-century red and black tiles. In the attic, there are three unequally-placed trusses with collar beams and raking struts.
