Description
Cwm-dwr is a farmhouse and outbuilding built from rubble stone, which was formerly whitewashed, and features a slate roof with large roughcast external end stacks, the one on the right being larger. The building is two storeys high and originally had a double front but now has an added first-floor centre window. On the first floor, there are small-paned casement windows on either side and a single casement window with brick sides in the centre. The original windows have timber lintels, while the centre window has a concrete lintel. On the ground floor, there are 12-pane sash windows on either side of a 20th-century glazed door, with stone voussoirs above all three openings. The rear of the building is whitewashed and has an outshut on the right half. Attached to the left is a low, whitewashed long outbuilding with a corrugated iron roof. This outbuilding features a window on the left, followed by a door, a broad entry, and an altered opening with a window above blockwork.
