Ballynascreen House, 39 Shore Road, Greenisland, Carrickfergus, BT38 8UA

Ballynascreen House is a five-bay two-storey house with attic and basement, built around 1870, facing south on the east side of Shore Road. The building is rectangular in plan with two two-storey returns to the rear, a single-storey extension to the west gable, and an additional building attached to the north gable of the returns.

The pitched natural slate roof has two wall-head dormers to the front pitch and one to the north, each with a rolled lead ridge. Rendered chimneystacks feature bellcast coping and circular terracotta chimney pots. The eaves are overhanging with sheeted timber and plain bargeboards. Cast-iron rainwater goods in ogee profile drain the roof.

The walling is roughcast with a moulded string course over a roughcast plinth. Windows are square-headed 1/1 timber sliding sashes. Those to the principal elevation have moulded architraves and precast masonry cills; those to the ground floor are pedimented. The principal south elevation is five openings wide at each floor. The central entrance is contained in a single-storey porch with balustraded parapet. The recessed entrance has chamfered reveals and is surmounted by a round-headed lead-covered canopy supported on Ionic columns with a dentilled entablature. The double-leaf timber six-panelled entrance doors feature timber carved swag detail and a radial stained glass fanlight above, with an original brass door knob and bell. Access is by four masonry steps enclosed by a plinth wall to each side, with a window to each cheek. The ground floor has two windows to each side; the first floor has five windows. The left gable is abutted by an extension to the ground floor, with two plainly detailed windows to the first floor and two diminished windows to the attic. The extension has paired windows to the right and two smaller windows to the left, all plainly detailed, with two small windows below the plinth lighting the basement.

An L-plan return abuts the adjoining north elevation of the extension and main block, with a hipped roof and otherwise detailed as the house. Openings consist of a stained glass window to the right projecting side, a door to the left cheek, and a single window at the first floor left. This return is further extended by an attached house detailed as the main block.

The north elevation is abutted by a two-storey return to the east and a one-and-a-half-storey return to the west with an internal courtyard to the centre. The right gable has three windows to the ground and first floor and two to the attic. This is abutted by a two-storey return to the right which adjoins the attached building; the ground floor has a window to the left and a uPVC door to the right, with two windows at the first floor. The adjoining building has uPVC windows throughout.

The house is set within mature gardens to the south, east and west. The shore bounds the property to the east, and Shore Road to the west is bounded by random rubble walling. An attached two-storey house with principal access to the west gable has a series of modern extensions to the north. It is detailed as the main house but has uPVC windows throughout. Access to both houses is shared with that of neighbouring houses to the south.
