Description
Plas Holland is a large house constructed of stone and painted white, featuring a slate roof. The building is two storeys high and has three bays, with a central hallway and reception rooms on either side. The front door is made up of four panels, and there are sixteen-paned sash windows on both sides of the door and on the first floor. On the side of the house, there are two small Gothick windows that serve the parlour. At the rear, there is a single storey and attic wing, likely from an earlier house, which includes two gabled dormers on the east side, along with 20th-century extensions to the west. On the west wall, there is a tablet inscribed with an englyn that dates the house to 1786, mentioning 'my cell and costly castle' and signed by Jeffrey Holland. The property was not accessible at the time of inspection.
