Description

Maes-gwyn is a two-storey building constructed of colourwashed stone with a slate roof. It features a two-unit plan that includes a central entrance, a stair hall, flanking reception rooms, and narrow rear service rooms. The building has gable stacks and a central six-panelled door that is enclosed in a later added gabled porch. The windows are timber cross framed with old glass set in small quarries, and there are small iron casements with segmentally arched stone heads on the ground floor. The property was not accessible at the time of inspection in October 1995.
