Description
Bryn Eithin is a single-storey cottage featuring a two-room layout with end stacks. Attached to the left is a single-room section, which may have been used separately or could have served as a wash-house for the entire terrace. The cottage is constructed from limewashed rubblestone and has a slate roof with rendered stacks and slightly raised verges on the left side. The main part of the cottage has a central 19th-century four-panel door, with the top panels now glazed, set in a slightly projecting surround. This door is flanked by original 16-paned sash windows with painted slate cills. The section to the left includes a plank door on the right and an original 12-paned sash window on the left. The interior was not accessible during the survey.
