Coolmere, 45 Greencastle Street, Kilkeel, Newry, Co Down, BT34 4BH

Coolmere is a two-storey, three-bay Victorian villa of simple classical proportions and symmetrical design, located on the east side of Greencastle Street in Kilkeel. Dating from the mid-to-late 19th century (first cited in the 1868 valuation revision book, with construction dated 1860–1879), it forms part of an attractive pair with the identical house to its left, now incorporated into the Kilmorey Arms Hotel.

The principal elevation faces the street. The hipped natural slate roof is topped with two two-stage dashed and granite coped chimneys positioned one to either side of the central bay. Half-round metal rainwater goods run along projecting granite eaves. All walls are lined with cement render over a chamfered granite base course, with projecting ashlar quoins (pecked and fielded) to the corners of the façade only.

The entrance is approached via two shallow granite steps leading to a central four-panelled grained timber door flanked by similar panelled and glazed sidelights. Above is a semicircular fanlight with 'Coolmere' painted on in gold and red, set within a granite post and block opening with flush keystone and impost blocks. The ground floor features single tall 2/2 (vertically divided) grained sliding sashes with granite cills in the left and right bays, with three similar windows to the first floor positioned in line with the ground floor openings but reduced in height.

The left elevation contains a single 2/2 window centred on each floor. The right elevation is blank. At the rear, the middle bay is advanced to form a stairwell, which is abutted by a substantial modern single-storey return built circa 1983. The remaining wall of the main block matches the façade. The ground floor rear has a 2/2 sliding sash window to the right and a similar window flanked by 1/1 sashes to the left. The first floor has a 2/2 sash to the left and right bays. The stairwell contains a 2/2 sash at the half landing between ground and first floors, and a 1/1 sash between first floor and attic.

The rear return has a hipped natural slate roof with concrete ridges and plastic rainwater goods, with a chimney on the exposed gable. Its walls are rendered, and all windows are modern stained timber casements.

The front area is paved with hexagonal concrete tiles and enclosed by a chamfered granite dwarf wall supporting modern steel railings, with granite posts at either end (rendered at the right). Single chamfered granite posts at the front support a modern wrought metal gate. Carriage gates to the rear are set at an angle on the rear left corner, consisting of squared dressed granite piers supporting corrugated metal gates. The rear garden, approached by a pair of embattled granite gate posts, is enclosed by a high coped granite rubble wall and contains a rendered two-storey outhouse of no special merit.

The building retains much of its original external character, though the modern rear extension and contemporary alterations to windows and railings detract from its historic fabric.
