138 Upper Road, Greenisland, Carrickfergus, Co. Antrim, BT38 8RL

A well-proportioned early twentieth-century semi-detached three-bay two-storey house with attic, built around 1910 and located on an elevated site to the north of Upper Road, Carrickfergus. The building forms part of a symmetrical pair with No. 140, creating a group of local interest.

The house is rectangular on plan with a two-and-a-half-storey projecting gabled left bay featuring an additional two-storey canted bay to the centre, and a two-storey pitched roof return to the rear. The roof is hipped (pitched to north gables) and covered in natural slate with crested terracotta ridge tiles; ogee-profile cast-iron rainwater goods run beneath moulded eaves supported on a dentilled course. Three rendered stepped gable chimneyStacks with terracotta pots stand on the building—one rendered to each of the main gables and a second to the party wall—with a single roof light to the north slope.

The walls are roughcast rendered with a moulded stringcourse and smooth rendered plinth. Windows are predominantly 1/1 sliding sashes with painted masonry cills and moulded architraves, though north return windows lack moulded architraves. The principal elevation faces south. The two-and-a-half-storey left gable is topped by a dormer with pitched natural slate roof, plain timber bargeboards and a terracotta finial. The canted bay to the centre has a flat roof and contains single windows to each cheek at ground and first floor with a continuous cill, surmounted by paired square-headed windows to the gable. A central single-storey projecting entrance porch with a natural slate hipped roof is set within the internal angle; this comprises a six-panelled timber door within a glazed entrance porch (panelled to the bottom), accessed by three precast concrete steps, and features crested timber eaves with decorative cast-iron cresting around a leaded flat roof. Paired windows stand to the right of the porch at ground floor. The first floor contains a central segmental-headed door opening onto the flat roof above the hipped entrance porch, with paired windows at the right; a single window stands in the left gable at each floor.

The rear elevation is largely abutted by a two-storey return with pitched natural slate roof, itself abutted to the left by a single-storey lean-to extension; the exposed section is blank. The right gable is abutted by No. 140. The return north gable is blank, while the west elevation contains two windows at ground floor and three windows at first floor. The east elevation contains a door to the left with two windows to the right, and a single casement window to the left at first floor.

The house is set parallel to the road on an elevated site accessed by a lane to the left, bounded to the road by mature trees and garden with garden extending to the rear. A single-storey pitched garage stands to the north. A boundary wall enclosing a small rear yard accessed by a timber sheeted door abuts the right corner.

The building first appears on the sixth edition Ordnance Survey map of 1920–21. Valuation Revisions record it in 1904 as a 'house, yard and garden' occupied by Lancelot Montgomery and leased from Susan Loughlin, valued at £27. In 1909 the occupier changed to Charles Montgomery.
