Description
Plas Deon is a two-storey late Georgian house built from local rubble, featuring a slate roof and end chimneys. The building has plain cornicing and weather-coursing. Its facade is asymmetrical with two windows and a central entrance that includes a nine-panel door with a rectangular overlight. To the far left, there is a larger boarded door with an overlight. On either side of the central entrance, there are large sash windows on both floors, which have original 6-pane upper sections and plain lower sections that have replaced the original 6-pane parts. The interior was not inspected during the survey.
