Description
Efail Bach is a single-storey cottage, likely dating from the 18th century. It is constructed of rubble masonry, which has been limewashed. The cottage has a slate roof with a tiled ridge, decorative coping, and Velux windows to the rear. Prominent, large rectangular gable stacks are rendered and have capping. The eaves line is high. The front of the cottage, facing a small garden to the northwest, features a central doorway with a modern door, flanked by small six-pane horned sash windows with slate sills. A later addition is visible at the rear. The interior was not inspected during the survey.
