East Wing, Mathern House

The house is constructed of local random rubble, rendered on the rear wall, and with a Welsh slate roof. It has two storeys and is L-shaped in plan, being an addition to the east gable of Mathern House. The garden front has a gable facing forward with two windows on the ground floor, cross-framed casements with leaded lattice lights, and there is a 3-light one in the gable above. Plain bargeboards to the gable, big kitchen stack on the return wall to the right. The left return has two 2-light windows, and there are two more at right angles to these and in line with the front of Mathern House. To the right is a single storey wing with the entrance door. The rear elevation has a modern lean-to across the ground floor with two windows and French casements; and two gabled half-dormers in the roof above which is hipped to the left.

Only the ground floor was seen at resurvey. It has been fully modernised and changed and only the main reception room is recognisable as the sometime Dining Room of Mathern House, while the dining room was probably the Kitchen.
