Oakleigh, 4 Parkmount, Belsize Road, Lisburn, County Antrim, BT27 4AN

Oakleigh is a three-storey, two-bay Victorian end-of-terrace townhouse built around 1900, located off Belsize Road north of Lisburn town centre, directly adjacent to Wallace Park. The building has a square plan form with a large two-storey rectangular rear return.

The roof is natural slate with a hipped form and clay finial over; leaded hips and crested clay ridge tiles complete the covering. A large stucco cavetto cornice at eaves level is painted white, with cast-iron ogee moulded gutters to the front and side elevations and semi-circular cast-iron gutters to the rear. Large section box cast-iron downpipes run down the front elevation. An altered brick chimney stack sits over the ridge line with six large clay pots; it has been reduced in height with the removal of corbel courses and the installation of a concrete flaunch.

The walling is red brick in Flemish bond with a projecting brick plinth that changes to English Garden Wall bond at the rear return. Windows throughout are single-glazed timber 1/1 sliding sash with horns, painted white, with large rectangular sandstone cills. Window openings are spanned by 1½ brick flat arches with brick keyblocks and moulded cornice detail over. The principal timber door features four bolection moulded, raised-and-pointed panels with a rectangular fixed light over, flanked by plain pilasters and decorated at cornice level with egg-and-dart moulding rising to large foliated console brackets supporting a cornice.

The principal south-facing elevation is asymmetrically arranged. The front door sits off-centre to the left, accessed by two stone steps and flanked by two windows: a half-circle arched timber-framed 1/1 sash to the left and a rectangular sash window to the right. The upper floors each have two equally spaced windows; first-floor windows have projected brick detailing under the cill, while second-floor window heads are embedded into the large cornice at eaves level. On the far right is a two-storey, shallow-pitched lead-covered box bay projecting from the corner at a 45-degree angle, with a single window to either side and paired windows to the front; a decorated terracotta string course rises over the openings to a corbel brick course at eaves level. The left elevation abuts the adjoining building 3 Parkmount.

The rear elevation is asymmetrically arranged with a large hipped two-storey return projecting northwards from the right-hand bay. Windows with reduced detailing are uniformly arranged on the left serving all levels. The return section is asymmetrically arranged and includes modern alterations to existing openings: a centrally located double-width sliding door with a single brick soldier course over, and to the right a new tripartite timber casement window with painted concrete lintel and concrete cill. Evidence of an infilled opening exists at ground floor. The rear chimney, which also serves the adjoining property, is located to the left over the ridge line and has had alterations to the upper brick courses. Some original cast-iron rainwater goods remain, though much has been replaced with uPVC. A metal-framed roof light sits to the left of the chimney stack, serving a light-well over the first-floor hallway. A further single-storey flat-roof modern extension projects northwards across part of the rear garden, abutting a masonry perimeter wall.

The right elevation is asymmetrically arranged, matching the detailing of the principal elevation. A large projecting bay sits at the left-hand side with a single window; to the right are uniformly arranged windows serving all levels.

The building directly overlooks the large mature trees and open green space of the adjacent Wallace Park and Lisburn cricket ground. To the west lies the remaining terrace block of matching style and quality. The front garden lies beyond a vehicular access to the other buildings within the group. The land to the side has been covered with tarmac to create off-street parking. The rear is enclosed by timber fence and masonry wall with no direct access from the rear, with modern dwellings erected beyond.
