Cnoc an Dudain, Ruisgarry

Cnoc an Dudain is a pair of adjoining single-storey, roughly rectangular-plan, rubble-built Hebridean-type cottages, likely dating from the late 18th or early 19th century. They stand on the north side of Bays Loch on the east side of the Isle of Berneray, to the west of Loch Watersee. The rubble walls of the cottages have squared corners and the windows are deeply recessed. Both roof structures have collapsed, with turf growing on the wallheads and the remnants of the roofs.

The southwest elevation has three openings. The northeast elevation has four irregular openings. Each cottage has a later porch addition. The porch of the north cottage is on the northeast elevation and has a shallow-pitched corrugated metal roof. The porch of 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 centre and one at the southeast end. There are at least two four-pane timber sash window frames in place with no glass.
