21 Sandy's Street, Newry, Co Down, BT34 1EN

This is one of five three-storey, two-bay terraced houses located on the south side of Sandys Street, Newry. It likely dates from between 1820 and 1839, and is shown on an Ordnance Survey town map of 1835.

The front elevation retains many original features, although a replacement roof and the loss of the front door and entablature have diminished the overall integrity of the building. The street façade is painted with lime render, featuring a raised eaves course and a raised painted base course. The main entrance, now on the right-hand side, is a modern four-panel timber door with a narrow transom light above. A single 1/1 sliding sash window sits to the left, with an exposed box. Three identical window openings are irregularly spaced on the first and second floors, with the right-hand windows aligned with the door, and the top-floor windows reduced in height. All the window openings have stop-chamfered reveals, with granite sills. The left and right gables are shared party walls with the adjoining properties. The rear wall is painted and wet-dashed with cement, and a two-storey return abuts the left bay. The ground floor opening of the main block is not visible. First floor bay windows are present on the right, and each second floor bay has a 2/2 sliding sash window, all with granite cills. The return features a natural slate hipped roof with a skylight to the left pitch, and has two 2/2 sliding sash windows on the first floor of the back wall. The rear yard is enclosed by a two-storey outhouse constructed from random rubble. The roof has artificial slate, with a cement-rendered chimney on the left. Semicircular metal rainwater goods are on the front façade, with a shared downpipe to the right (with number 20). The rear pitch has plastic rainwater goods with a downpipe to the right.

The building was occupied by John McKee in 1838, as noted in valuation records. In 1863, the building was described as being 18 feet 9 inches long by 22 feet 6 inches wide and three storeys high. The building is located within a conservation area. It was previously listed under the Windsor Hill ward designation HB16/26/055, but was delisted on 29 March 2006.
