Cnoc an Dudain, Ruisgarry

Cnoc an Dudain is a pair of adjoining single-storey cottages built from rubble, likely dating from the late 18th or early 19th century. They are located on the north side of Bays Loch on the east side of the Isle of Berneray, west of Loch Watersee. The cottages have squared corners and deeply recessed windows, but both roofs have collapsed, with turf now growing on the wallheads and remnants of the roofs.

The southwest elevation features three openings, while the northeast elevation has four irregular openings. Each cottage includes a later porch addition; the porch on the north cottage is located on the northeast elevation and has a shallow-pitched corrugated metal roof, while the porch on the south cottage is on the southwest elevation and has a pitched corrugated metal roof.

The building has two square concrete chimney stacks, one at the center and one at the southeast end. There are at least two four-pane timber sash window frames present, although they do not have glass.
