6 Trevor Hill, Newry, Co Down, BT34 1DN

6 Trevor Hill is the right-hand element of a symmetrical pair of three-storey townhouses with basements, built in the classical revival style and fronting the east side of Trevor Hill in Newry. The building dates to the early 19th century (1800–1819) and retains most of its original external features. Its significance lies not only in its architectural quality but also in its important group value with the adjacent property and its contribution to Trevor Hill as a whole.

The façade is three windows wide across two bays. The pitched roof is laid with natural slate and has three modern skylights to each pitch. A cement render chimney with a projecting cap rises from the right gable. Behind the cornice of the main façade, a gutter feeds into a plastic downpipe at the right; white plastic rainwater goods serve the rear.

The main walls are painted lined render with plain double cill courses to the first floor, a single cill course to the second floor, and a plain double cornice course at the eaves. The ground floor contains the principal entrance at the left, accessed by five granite steps. The door opening has a segmental head with painted ashlar granite jambs and voussoirs featuring a raised keystone. A modern brass plaque is mounted on the right jamb. The front door itself is painted timber with six raised and fielded bolection moulded panels and modern furniture. It is framed by a pair of granite Doric demi-columns supporting a moulded granite entablature. Above this sits a segmental fanlight with leaded spider-web tracery. To the right of the entrance are two 6/6 sliding sash windows with horned bracketed cills and moulded stucco architraves.

The basement has two 3/3 sliding sash windows with painted granite cills aligned with the ground floor windows; these now have modern fixed security bars. An external passage runs in front of the basement, paved with quarry tiles. At the left end of this passage, on the right cheek below the front steps, is a modern tongued-and-grooved timber door with a ventilation slit.

At first-floor level are three 6/6 sliding sash windows with horns, aligned with the ground floor openings and fitted with similar architraves but enhanced with an additional frieze and projecting cornice. A security alarm box is positioned between the first and second windows from the left. The second floor contains three 3/6 sliding sash windows with horns and moulded architraves, diminished in height. The right gable has plain unpainted cement render with a security alarm box at first-floor level; the left gable is a party wall shared with the adjacent property.

The rear elevation is cement rendered. At ground floor, the left end has a small 2/2 casement window; to its right is a large 6/6 sliding sash and a sheeted door with sidelights. Between ground and first floors on the right is a semicircular-headed 6/6 half-landing window; another identical window sits between first and second floors. A single 6/6 sliding sash is positioned at first-floor level below the half-landing window. At second-floor level is a 3/6 sash window, diminished in height and aligned with the first-floor opening. All windows are sliding sash replacements. The rear yard is enclosed by a high rubble stone wall (partially rendered) separating it from nos. 5 and 7 Trevor Hill.

The basement and front steps are enclosed by original plain spiked railings featuring urn-topped posts at the base of the steps and a boot scraper inset to the left of the front door.

Trevor Hill was laid out in the late 18th century and developed during the early 19th century. This property appears on the 1835 Ordnance Survey map and is described in the 1838 valuation as a dwelling house occupied by a Mr Mathew Fletcher. Before 1863, it was taken over by the Belfast Banking Company, which likely maintained a manager's house on the upper floors. The bank relocated to new premises at 2–3 Trevor Hill in the early 1890s. The Newry Loan Company, an early credit union, subsequently occupied the building. A photograph from 1894 shows this building as it appears today, alongside the newly completed Belfast Banking Company premises.

The building's extent of listing includes the house, wall, and railings. It is situated within a conservation area.
