Description
1-12 Gelli Houses were built in 1883 for coal miners working at nearby pits owned by the Glyncorrwg Coal Mining Company. This single-storey construction is unusual and represents one of the latest examples of this housing type. Each house has four rooms and a lean-to pantry at the back, with only two of the rooms originally heated. The houses initially shared a communal bakehouse, which had been demolished by 1904.
The buildings consist of two rows of six double-fronted houses arranged end-to-end but not quite parallel. The walls are made of rubble stone and have been rendered, while the roofs have been renewed. Most of the brick chimney stacks remain, with some also rendered. The windows and doors have been replaced, mostly in their original openings. Some houses feature enlarged windows and a replaced tile roof.
