Description
Glan-dwr is a small house constructed of rendered rubble stone, with the front whitewashed. It features a slate roof and stone stacks at both ends. The building is two-storey with a three-window front, showcasing 12-pane hornless sash windows, slate sills, and a four-panel door with an overlight. The rear elevation is made of rubble stone and includes three similar windows on the first floor and one on the ground floor to the right. There is also a nine-pane casement window on the ground floor to the left, along with a central boarded door. The windows have stone lintels and slate sills. A cobbled path, approximately 1 meter wide, runs from the rear wall along the length of the cottage.
