Islandreagh Cottage, 230 Belfast Road, Dunadry, Co Antrim, BT41 2EZ

Islandreagh Cottage is a detached three-bay one and a half-storey rendered house built around 1840, facing south and located at the end of a long lane north off the A6 near Dunadry.

The building is rectangular on plan with a pitched natural slate roof featuring black clay ridge tiles. A yellow brick chimneystack rises from both gables with a cement cornice, clay pots and lead flashing. The roof has a synthetic covering to the verge, cast-iron half-round gutters on drive-in brackets to a smooth render eaves course, and cast-iron downpipes. A solar panel is fitted to the front pitch and a Velux window to the rear pitch.

The original walling is painted rough-cast render with a smooth render plinth course and render soldier quoins. Windows are square-headed with chamfered sandstone sills and timber sash windows throughout.

The principal south-facing elevation is symmetrical. Above the front entrance is a central wallhead dormer containing a round-headed window opening with smooth render surround and keystone, fitted with a 3/6 timber sash window with fanlight and ogee horns, installed around 1990. To either side of the front entrance are square-headed window openings with smooth render surrounds, keystones, and 8/8 timber sash windows with angled horns and much cylinder glass. The central elliptical-headed front entrance has render reveals and a smooth render surround with keystone and plinth blocks. A replacement timber doorcase from around 1990 comprises a square-headed door opening with a flat-panelled timber door and Art Nouveau brass furniture, flanked by slender panelled pilasters, multi-pane sidelights on panels, and a further pilaster to either end with a lintel cornice stepping out to the pilasters. An original iron spoked fanlight spans the doorcase. The door opens onto a tiled concrete stepdown to the front gravel area.

The west gable elevation has an attached timber conservatory erected around 1995, containing two ground floor window openings with square-headed openings, smooth render surrounds, chamfered sandstone sills, and 6/6 timber sash windows with no horns and some cylinder glass. An additional window on the ground floor has angled horns, and there is a further 6-pane fixed timber window.

The east gable elevation has three square-headed window openings, with a further blocked-up former opening. All have smooth render surrounds, chamfered sandstone sills, and 6/6 timber sash windows. The first floor window has no horns (sourced from Ardnaveigh and being repaired at time of survey), whilst those on the ground floor have angled horns.

A central single-bay two-storey return extension with catslide roof was built to the rear around 1940, adjoining a further single-bay single-storey extension to the northwest, built around 1970. The north and rear elevations are now largely obscured by these extensions, which feature replacement timber casements. A square-headed door opening with vertically-sheeted timber door opens onto a concrete step to a rear gravel yard.

A two-bay flat-roof single-storey garage abutting the rear elevation and return to the northeast was built around 1970.

The house is set in fields down a long lane from the road with a garden and rear yard. Remnants of rubble stone outbuildings remain to the northwest of the house. A modern bungalow has been built to the west. Abutting the north end of the garage is a rendered wall with a decorative carved stone lintel and a pair of octagonal stone gate posts; several stone architectural artefacts adorn the site, all added by current owners during the last 30 years. A double-height corrugated iron hay barn with a corrugated iron barrel roof is located to the northeast. The landscaped grounds contain several mature trees with the gravel drive continuing south enclosed by traditional hedgerow and opening onto the A6.
