Glassmount House

Glassmount House is a large house dating to the later 19th century, with an earlier 19th-century wing and 20th-century additions to the rear. It is a tall, two-storey building originally with two bays, now extended to five bays, and designed in a Tudorbethan style with decorative details. The house is built with small ashlar bands and cement render, featuring rusticated quoins and ashlar dressings. A deep base course and moulded eaves cornice are prominent, along with hoodmoulds, tabbed and architraved window surrounds, chamfered arrises, and stone mullions.

The main, east-facing elevation has an advanced, gabled section to the right of centre, supported by square-section columns and outer scroll brackets to form a bracketed stone balcony. This balcony acts as a doorpiece with steps leading to a deep-set panelled timber door with a plate glass fanlight and flanking windows. Above the door is a hoodmoulded bipartite window set within a moulded panel in the finialled gablehead. To the right is a full-height canted four-light window on each floor, culminating in a stepped blocking course and corbelled, finialled gablehead. The recessed wing to the left has a slightly advanced, pedimented centre bay with three windows to each floor. The centre ground-floor window is keystoned and architraved, with regular fenestration to the flanking bays.

The south elevation features a gabled bay with a full-height, three-light canted window, incorporating a centre door at ground level. A sundial dated 1722 is inset into the gablehead. The north elevation mirrors the east elevation with a full-height, four-light canted window.

The west-facing rear elevation exhibits a variety of additions, including a slightly advanced gable to the right, a dormer gablet to the left, and a low lean-to extension at ground level.

The windows are timber sash and case with four panes to the lower sashes and plate glass to the upper. The roof is covered in grey slates. The house has coped ashlar stacks with decorative cans, gablet ashlar-coped skewes and skewputts, and stone finials. Cast-iron downpipes with decorative rainwater hoppers are also present.

Inside, the house retains plain and decorative cornices, panelled shutters, timber fireplaces (some carved), a mosaic-tiled entrance hall with a screen door, a cantilevered dog-leg staircase with decorative cast-iron railings, and a fine coloured glass oval lantern.

Glassmount appeared as 'North Glassmount' on the first Ordnance Survey map of 1855. A very fine conservatory located immediately to the west is listed separately, as are the sundial and steading.
