Limekiln Cottage, including revetment walls and steps

Limekiln Cottage, together with Cornhill Cottage, forms a pair of two-storey, two-window houses constructed from large slate-stone blocks laid in regular courses, with a slate roof and two later, small, roughcast stacks. Cornhill Cottage, on the left, features a replacement glazed front door and replacement two-light casement windows set within original openings. Limekiln Cottage has a former doorway now replaced with a window on the right-hand side, an enlarged modern window to the left, and two-light casement windows in the upper storey, also within original openings. A modern, white pebble-dashed rear wing provides access to the cottages, with a modern glazed door. A boarded door and overlight on the left side of Cornhill Cottage provides access to a yard behind No. 15 Cornhill.

Two revetment walls, constructed from coursed, unworked slate-stone, retain the steep ground from street level up to the entrances of the cottages. The lower revetment has a concrete coping, and gateways with slate orthostats provide access to slate steps leading up to the houses. Coping courses are present on the return walls of both sides. The cottages belong to a wider group.
