Description
Brithonfa is a symmetrical two-storey, three-window house built from random stone and topped with a renewed slate roof featuring stone end stacks. The central entrance consists of a boarded door with a small light above it, all under a timber lintel. This door is flanked by 12-pane hornless sash windows. Above, there are three similar windows that align with those below, rising to the eaves. There is evidence of earlier openings with timber lintels on the outer sides of the ground floor windows. At the rear, which is partly visible, there are two ground floor openings with segmental brick heads and a two-light wooden casement window on the upper right. Access to the interior was not available at the time of inspection.
