Shown on the 1839 Tithe Map, the cottage is likely to have been built only shortly before this date, its occupants probably working in one of the neighbouring slate quarries, most probably the Penrhyn Slate Quarry near Bethesda, which was rapidly expanding at this period. The cottage is typical of those slightly later cottages sited at some distance from the quarry where the distance from the quarry was compensated for by the location in better-quality agricultural land, of which the part allocated to the cottage was worked by the occupants for their own use. The single-room section may be an addition to the original cottage.

A single-storey building of linear form, aligned roughly north-south, the larger part to right (south) of 2-unit plan with very slightly lower single-room section on left. It is constructed of roughly coursed rubblestone with a slate roof with purple brick coping to the main part. This has 4-paned casement windows with slate cills on either side of offset, boarded, door under bracketed lean-to hood and rendered integral end stacks. The section to the left has a 12-paned sash to left of a boarded door and a rendered integral end stack. There is a small 20th century extension at the rear.
