Islandreagh, 2 Islandreagh Road, Dunadry, Antrim, Co Antrim, BT41 2HF

Islandreagh is a detached three-bay two-storey Georgian house built around 1760, located north of Belfast Road and accessed from Islandreagh Road. The building has a rectangular plan with a single-storey extension to the north-west corner and a one-and-a-half storey extension to the east that abuts an outbuilding now incorporated into the house. The pitched slated roofs have overhanging eaves, and brick chimneys rise from the gable ends of the main house. The walls are roughcast over a smooth painted plinth.

The principal south-facing elevation features three bays with the central bay containing an entrance door surmounted by a window at first-floor level, and flanking bays with single windows to each level. The door sits within a segmental-headed recess with a moulded timber segmental-headed arch on exaggerated ogee stops. The door itself is timber panelled (replaced around 1980) with a segmented fanlight and decorative sidelights. The windows throughout are exposed box 6/6 sliding sash timber with margin lights and painted masonry cills, unless otherwise stated.

To the east of the principal elevation is a one-and-a-half storey extension with a slated lean-to entrance porch featuring uPVC glazing, surmounted by a half dormer containing a double 6/6 sliding sash timber window divided by a timber mullion. A single window sits at ground-floor level, and a single-storey link block with a replacement 12/12 casement window connects the extension to the outbuilding. The outbuilding gable end is marked by a central pitched gable-ended bay.

The west elevation contains a single ground-floor window and two first-floor windows, with the left-hand first-floor window lacking margin lights. A single-storey canted sunroom extension occupies the north-west corner. The exposed north elevation displays a large timber casement window divided into panes at first-floor level. A central two-storey gable-ended stairway return, built around 1980, has a half-landing lit by a round-headed arched window with masonry cill.

The east rear elevation comprises a single-storey extension with an overhanging mono-pitch slated roof, two small square timber casement windows to the left, and a modern timber-panelled entrance door to the right. This is abutted by the one-and-a-half storey extension with a gable-ended lucarne containing windows to both ground and first floors. A pitched link block connects this section to the outbuilding. The outbuilding, incorporated into the house around 1980, features square-headed openings on the west elevation and two square-headed window openings and a door opening on the east elevation.

The house stands within mature gardens, bounded to Belfast Road by random rubble walling and to Islandreagh Road by hedging and roughcast walling. Access from each road is via brick pillars with modern gates. A range of outbuildings lies to the rear (north): a multiple-bay two-storey random rubble stable building with brick detailing, original vertically-sheeted timber doors to each level, and replacement exposed box timber 6/6 sliding sash windows; an open shelter with corrugated roof abutting to the west; and a two-bay single-storey byre with original sliding vertically-sheeted timber doors and casement windows abutting to the east.

The roof covering is natural slate. The windows are timber-framed 6/6 sliding sash. Rainwater goods are cast iron replacement half-round gutters and round downpipes.
