The entrance is slightly to the right of center and features a boarded door. Flanking the entrance are small four-pane wooden windows with slate sills. On the upper storey, there are two two-light wooden casement windows with slate sills, positioned immediately under the eaves and not aligned with the windows below. The west gable end has no openings and is not rendered. The rear of the building was not visible. Attached to the east gable end is a single-storey unit that is rendered and also has a slate roof. This unit features a boarded door on the right and a four-pane wooden window on the left. There is a stone lean-to against its east end, which has corrugated iron sheeting and an opening to the front. The interior was not seen during the resurvey.
