Description
Cefndeuddwr Farmhouse is a 17th-century building with an end chimney plan, constructed from whitened, rendered rubble and topped with an old slate roof. It features tall chimneys, with the one on the left side (the hall end) being larger, both having plain capping and weather coursing. The front has three windows, which are 19th-century 12-pane recessed sash windows. There is a plain modern door set within a modern flat-roofed rubble porch. The rear of the house is made of rubble and includes a centrally placed gabled dormer with a renewed 12-pane sliding sash window and an original timber lintel.
On the right side, there are two single-storey gabled projections, with the right one being advanced and wider. The left projection has a tall gable-end chimney with a cornice and weather coursing. A 9-pane 19th-century sash window is located on the south return of the right projection, which also has a modern rubble and timber porch extending southward. The gable ends of the main block are rendered.
Inside, stopped-chamfered ceiling beams from the former hall and parlour are believed to be preserved behind the plaster ceiling, with the large transverse beam in the hall being visible. The hall features raised and fielded early 18th-century dado panelling. There is a reduced fireplace with its bressummer removed, and to the right, access to a newel stair is apparently concealed in a blocked cupboard. The cross-passage has half of the original post-and-panel partition visible on the left, with moulded and chamfered edges, and a small light cut into it (dating to the late 17th century) featuring S-shaped slats.
A fine early 18th-century dog-leg stair showcases panelled newel posts, a sloped rail, and turned balusters, with original treads and risers. The ground floor includes early 18th-century 6-panel doors that are raised and fielded. A post-and-panel screen on the right side of the first floor unusually projects out at the top in a jettied manner, featuring a moulded oak cornice and returning to enclose a small 18th-century former wig closet with a contemporary 2-panel raised and fielded door, along with compartmented shelving that has moulded edges. The house retains largely contemporary oak floorboards throughout and three additional 18th-century doors, with raised and fielded panelled window embrasures on the main windows of both floors.
