Gattws Parc including Boulder Wall adjoining to NW

Gattws Parc is a small one-and-a-half storey rectangular building constructed of rubble, situated on a steep hillside. It features a graded slate roof with slab-coped and kneelered gable parapets, and a squat end chimney on the south gable with moulded capping and weathercoursing. The building has gabled dormer windows on both sides of the roof, also with kneelered and slab-coped gable parapets, and modern windows in the main openings. The entrance front, facing west, is whitened and has an angled entry leading to a boarded door that opens into a low, partly subterranean modern extension on the left. There is a 6-pane casement window on the ground floor with a blocked original opening to the left, a similar window at the rear, and two small square windows on the upper south gable. A modern rubble terrace wall is attached to the west side.

To the northwest, behind the gatehouse, there is a dry-built boulder-rubble boundary wall that extends uphill for about 50 meters, likely dating from the 17th century. This wall ends at the upper drive and is contemporary with the boulder-built enclosing wall to the northwest of the Parc complex.

Inside, the building has single-room floors, with the upper floor open to the roof. Slate-stone steps to the left of the entrance lead to this upper floor, featuring re-used 17th-century balustrading, and the ground floor is flagged. The roof consists of a 2-bay pegged oak collar truss with original purlins.
