Description
Glen Hir is a symmetrical, two-storey house of double depth, likely dating to the 18th century. It has an advanced central bay to both the front and rear elevations, with a lower service wing attached to the east. The house is constructed with double-skin brick, originally faced with roughcast render. It is characterised by pronounced hipped, swept tiled roofs. At the apex of each ridge is a decorative feature consisting of the base of a bottle surrounded by a spiral of tiles on edge. Tall, rendered stacks are positioned at each end of the house, with two at each end and a further stack rising from the central valley. The windows are horned sash windows with flat heads and stone sills.
The advanced central entrance bay features double-panelled doors within a moulded doorcase, topped by a segmental pediment supported on decorative consoles. Narrow eight-pane sash windows are situated on either side of the entrance bay, with three similar windows to the upper storey. In the main range, pairs of windows are arranged; twelve-pane sashes to the upper storey and six-over-nine-pane sashes below. All openings include blue-painted wooden shutters.
The garden front, which faces the rear of the house, also has an advanced bay fronted by a single-storey canted bay with a flat roof. A central glazed door, with a six-pane overlight, is accessed by stone steps. Sash windows to the sides mirror those on the front elevation, although the lower glazing bars are missing. Flanking the advanced bay are pairs of windows resembling the front, except for a wide tripartite window to the bottom left, featuring three sash windows. All openings have blue-painted shutters, and the lower storey windows lack glazing bars to the lower sashes.
On the west end, between the projecting stacks, there is a pair of twelve-pane sashes to the upper storey, with a six-over-nine-pane sash below to the left. A slight projection to the right contains a small hatch, potentially for coal delivery. The lower service wing to the east features a half-hipped roof, a half-lit door to the front, no rear openings, and three upper-storey windows. A long, single-storey range projects from the northeast angle, with a panelled door to the front (formerly half-lit) and two half-lit doors with small windows to the east side.
Inside, the entrance leads to an L-shaped hall. Reception rooms are located to the south (garden front), a large billiard room spans the west end of the house, and a rear staircase is immediately next to the entrance. The service area, now used as kitchens, is situated to the east. The central reception room includes decorative plaster panelling and an original, moulded wooden fireplace with a square head; other fireplaces have been replaced. Decorative coving is present throughout the house. The billiard room has timber beams and joists to the ceiling. An open-well staircase features square panelled newel posts and narrow, closely spaced decorative balusters. The ceilings are high, and the walls are unusually thick due to the double-skin brick construction.
