Description
Menascin House is a late Regency medium-sized gentry house with a roughly L-shaped plan. It has a garden frontage facing south and east-facing bays that provide views of the Usk Valley and the mountains. The house is constructed of rendered stone, mostly roughcast, and features a Welsh slate roof with deep overhanging eaves and decorative bargeboards, along with end ridge stacks. It stands three storeys tall with a cellar. The garden frontage includes a central gable with one window at this level, while the other windows are asymmetrically spaced to accommodate the second bayed frontage. There are two 6/6 pane sash windows on the first floor and a small circular light at the end right. On the ground floor, there is an 8/8 pane sash window on the left and a remodelled French window on the right, along with a small hipped wing to the left.
The side frontage features two parallel three-storeyed separately gabled bays, with the right bay stepped back. Each bay has an unusual tear-shaped oculus in the apex, with the right being blind and the left having a hinged casement. Below each apex is a two-storeyed glazed canted bay, with single pane casement openings and gothick glazing in the top lights. The rear entrance elevation mirrors these features, including a blind oculus, a 6/6 pane sash window, and a deep porch with scored render, decorative bargeboards, and internal steps leading to a recessed six-panelled door with a fluted surround and panelled reveals. There are also steps down to the basement, which has a window at the base of the right front bay. The property is accessed through gatepiers made of tooled stone and double iron gates topped with spear finials.
Inside, the door opens onto a hall with an adjacent staircase along the right side of the house. The main rooms open to the left, and the hall concludes in a pantry with a kitchen to the right, forming the L-shaped plan. The interior features many Regency details, including fluted surrounds with rosettes on doors and bays, six-panelled doors, and basket arches. The staircase has stick balusters and a wreathed handrail, and there is a marble fireplace with brackets and moulded wall recesses.
