19 St. Colman’s Park, Newry, Co Down, BT34 2BX

19 St. Colman's Park, Newry, is a three-storey granite house with basement, forming part of a seven-house terrace that slopes down the street. Built between the 1820s and 1839 as part of James McAllister's mid-19th century town planning initiative for Newry, it represents an important example of that era's urban development. The terrace, shown on the 1835 Ordnance Survey map as "McAllister's Terrace", was noted as unfinished in the 1835 valuation but was probably completed shortly thereafter.

The building is constructed of squared rubble granite walls brought to courses, with a pitched natural slate roof and rendered chimney (shared with number 17) at the right. It is three bays wide and stands at the same height as number 17.

The street façade is of considerable architectural merit and forms a cohesive part of the terrace which makes up one side of the square. At ground floor, the central bay contains a modern four-panel painted timber door with rectangular transom light above. The flat-headed opening has splayed voussoirs in ashlar granite with a projecting keystone and imposts, and vee-jointed ashlar jambs. To the left is a coach arch with vee-jointed ashlar jambs and semi-elliptical head with imposts and projecting keystone, now containing a pair of modern metal gates. To the right is a semi-elliptical headed window opening with identical surround to the coach arch. It contains a smaller rectangular 6/6 sliding sash window, with the space between its frame and arch reveal cement rendered. Below this, the in-splayed flat granite lintel of the former basement is just visible.

At first floor are three 6/6 sliding sash windows, one positioned above each opening below, with granite cills. A projecting hanging sign is positioned between the two windows at left. At second floor are three 3/3 sliding sash windows, also in line, with granite cills. Upper floor openings have cement-rendered heads and stepped jambs (undoubtedly over brick), and the first floor openings also have three-piece keystoned lintels above their rendered heads.

The front elevation is fitted with reproduction metal railings over a chamfered granite plinth with urn-topped posts, running along the small front garden and returning along the exposed side of the entrance steps. Similar railings also run between the coach arch and front door. These railings are consistent with those fronting the other houses in the terrace and the corner block fronting John Mitchel Place.

The building is abutted at left by the outbuildings of 21 St. Colman's Park and at right by number 17. At the rear, the walls are unrendered with half-round metal rainwater goods. A one-storey extension abuts the ground floor on its left two bays, obscuring the original openings, with the coach arch at right now brick-headed. The left and right bays have 6/6 sliding sash windows on first floor and 3/3 sashes at second floor. The middle bay has 6/6 sashes on the half landings between ground and first floor and between first and second floors, all brick-trimmed. Many upper floor windows have three-piece keystoned lintels above their brick heads. The modern extension has a flat roof, rendered walls and a modern window to the back wall.

At the rear of the back yard is a two-storey outbuilding contiguous with one at the back of number 17. It has a hipped asbestos slate roof, plastic rainwater goods and random rubble granite walls. The north wall is blank, and the right gable is abutted by a similar building. The yard elevation has a large rectangular opening at ground floor filled by a 15-pane door with 15-pane side panels on either side. At first floor right is a 3/3 sliding sash window. The left gable of this building is abutted by a one-storey flat-roofed extension with two 3/3 sliding sash windows to the yard elevation.

The building is currently in use as an office, having formerly been residential. It is within a conservation area. The property is listed at Grade B1 with extent of listing covering the house and railings.
