11 Trevor Hill, Newry

The left-hand building of a pair of three-storey granite houses with basement, built between 1820 and 1839 in the classical revival style. It fronts the east side of Trevor Hill and remains relatively unaltered, representing a good example of this architectural type. The building is significant both in its own right and as part of an important grouping of imposing and elegant town houses in the area, though few interior details survive.

The house is two bays wide with a pitched natural slate roof featuring a skylight to the front pitch and a cement rendered chimney to the left gable. Half-round metal rainwater goods with a down pipe are positioned at the left. The façade walls are of squared granite rubble laid in courses with projecting eaves course.

To the ground floor left of the façade is a flanking wall containing a semi-elliptical headed coachway leading to the rear yard. The wall is rendered and the arch is finely dressed granite with raised imposts and keyblock, now infilled with a large sheet metal door. To the right, six granite steps rise to a paved threshold with a wrought iron boot scraper at the top. The main entrance features a modern twelve-panelled painted timber door flanked by a pair of fluted Doric demi-columns and an entablature with patera to the frieze, above which is a plain glass fanlight. All are set within a segmental headed opening with painted dressed granite trim; the right pier is shared with the coach arch belonging to the adjoining house.

At left of the front door are two 1/1 sliding sash windows with metal grilles over. A passage runs across the front of the basement, lit by two 8/4 sliding sash windows directly in line with those above, both fitted with metal security bars. The first floor has three equally spaced 1/1 sliding sash windows. The second floor has three 6/3 sliding sashes of diminished height and in line with those below. All window openings have stepped brick quoins, soldier course heads, painted and rendered reveals, and granite cills. Between the two right-hand windows on the upper floors, modern ventilation grills have been inserted. A clear wall break appears at right of the right-hand windows on upper floors but not at ground floor.

Railings enclose the basement and steps, featuring spiked plain rails and cast iron urn-topped posts resting on a granite plinth. Additional railings run up the steps to the entrance between the coach arch and front door. The right gable is a party wall with the adjoining house. The left gable is cement rendered. At ground floor left is a modern six-panelled timber door with transom over. At right is a modern fifteen-pane door with three-pane transom over fitted with modern security grille. Between these doors is a modern six-paned timber casement window with concrete cill and metal security grill. At first floor is a six-paned modern casement window with concrete cill.

The rear elevation is cement rendered. A single-storey extension abuts the ground floor. At first floor left is a 1/1 sliding sash window. At second floor is a 1/1 sliding sash window at left and a 6/3 sash at right. The middle bay contains half-landing windows set in semicircular headed openings: the one between ground and first floor is a 6/1 sliding sash window with spoked head; the one above is a 6/6 sash also with spoked head. The extension has a flat roof, cement rendered walls, and a modern timber door and window on the right cheek. A modern rendered wall encloses the rear yard, with a metal door leading through to a derelict outbuilding. Railings enclose the basement and steps as described above.

The building is shown on the 1835 Ordnance Survey map and was described in the 1863 valuation as three and a half storeys high, suggesting it has retained its original appearance. The building is listed as Grade B1 and is within a conservation area. Its current use is as offices.
