Description
Gelli Bach is a 2-storey, 2-window cottage built from limestone rubble, topped with a slate roof and featuring end brick stacks. The central door, which has been replaced, is boarded and is sheltered by a simple bracketed canopy. The lower storey has two-light casement windows with segmental heads and stone voussoirs, while the upper storey windows are positioned beneath the eaves. On the left gable end, there is a lean-to shed that has a front made of rubble stone, with brick walls on the sides and rear. At the back of the main house, there is a small fixed window located beneath the eaves at the center, along with an inserted boarded door to the left of center, but the rest of the rear wall is blank.
