Perth-eiryn

Two storeys, attic and cellar, timber framed, with slate roof, but a brick W front, and some framing painted on brickwork and corrugated iron. The main range consists of a hall and parlour with a gable stack, and a rear wing, forming a 'T'-plan, probably coeval, containing the present stair. The framing is close studded throughout, the S gable end jettied at gable level, and has tension braces. The W front is of Flemish bond brick, of 5 bays, with brick plat band and end pilasters, with further brick pilasters either side of the central bay containing the entrance to the former hall. The early smaller 5-bay equally spaced windows were replaced in early C19 with 2- and 3-light transomed timber windows with segmental heads, having iron casements and small panes. Over the C20 central glazed doors, a section of timber is built in bearing the date 1654. The brick stacks are rebuilt. Sash windows on the S front; oak cross windows at the side.

The hall parlour range has twin chamfered spine beams, and gable stacks, altered c.1960 when one fire beam was removed and re-used in the dining room of Plas Dinam, Llandinam. Some panelling reset over the former hall fireplace. C18 panelled doors. A stair of c.1900 with splat balusters probably replaces the original in the back wing, the end service room having a cellar under.
