Description
Pen-y-clogwyn is a 1½-storey farmhouse constructed from whitened rubble stone, featuring a slate roof and stone end stacks. The right end of the house is larger and original, while the left end is a later addition. The central entrance has a replacement half-glazed boarded door, flanked by replacement windows in earlier openings; the right-hand window is positioned at a higher level due to the sloping site. There are three late 19th-century gabled dormers, each with replacement 2-light casement windows and slate-hung sides.
To the left of the farmhouse is a lower outbuilding, likely originally a cow house, also made of whitened stone with a slate roof. This outbuilding has two replacement boarded doors, located at a higher level on the right side. The property has not been inspected.
