The stack at the south end is larger, and the facade is offset to the left. The cottage is single storey, with part of the loft space utilized. It has a double-fronted design that includes a 9-pane casement window on the left, a ledged door in the center, and a fixed 9-pane window on the right, all supported by slab lintels. On the rear wall facing the road, there is a small 4-pane sash window on the left and a 4-pane casement window on the right.
Inside, there is a croglofft over the north end and a fireplace at the south end, which features a stone slab lintel. The roof is supported by a collar-truss structure.
