9-10 The Mall, Newry, Co Down, BT34 1BX

9-10 The Mall, Newry is a four-storey brick warehouse of late 19th-century date, erected around 1900 as a tea warehouse to a design by W.J. Watson. It is one of few remaining unaltered warehouse buildings in Newry and represents an important building type reflecting the town's historical development as a port along the canal and river frontages.

The building has a symmetrical façade fronting the Mall with high quality robust brick detailing in mostly original condition. The pitched natural slate roof is topped with parapeted rendered gables, kneestones and copings, and terracotta ridge tiles. Three dormered loading doors feature natural slate roofs, slate-hung cheeks, and parapeted gables with kneestones and concrete copings. Plastic rainwater goods overhang exposed rafter tails, with four downpipes to the façade.

The principal façade is constructed of red brick with two-course strings of blue engineering brick between each floor and a moulded brick plinth. Each of the three string courses is punctuated by four regularly spaced circular tie-bar plates. Three brick dormers for hoisting beams punctuate the eaves course over the loading doors.

The façade is arranged in seven bays: three bays of paired windows alternate with three bays containing loading doors, with an additional bay of paired windows. All floors have four bays of paired windows. Doors on the ground floor are higher and wider. The left and centre door openings have original semicircular heads with curved brick reveals. The right door opening is rectangular with a modern aluminium shutter and box. The left and centre doors are pairs of panelled timber, not original. Other loading doors are pairs of reproduction panel doors with semicircular heads to the first and second floors. The top floor has pairs of four-panelled timber loading doors with semicircular lights over, though these have been infilled with modern tongue-and-groove panelling over the top doors. All window openings have curved semicircular heads and granite cills. Ground floor and first floor windows are higher, each with a fixed pane, semicircular transom over, and modern metal grilles. Second floor and third floor windows are each vertically divided and two-paned, with transom lights containing roundels except at ground floor level. Three modern spotlights have been mounted, one to the left of each first floor door. The left and right gables are abutted by lower blocks with plain cement-rendered exposed sections.

The rear elevation is largely obscured by a large single-storey flat-roofed extension at ground floor level, which spans much of the area between this building and the backs and returns of properties facing Hill Street. The extension links to Hill Street properties and is itself flat-roofed with several large hipped and gabled roof lights and a large projection to the north. The small exposed portion of the extension's east elevation appears to be brick, largely covered in creeping plant growth. The rear elevation of the original building is finished entirely in cement render except for a narrow section to the far right in brick, apparently originally a chimney breast now without a stack. A large full-height gabled bay occupies the left side of the elevation. To the left of the first floor level of this bay is a flat-roofed projection, cement-rendered with two small windows to its east face. To the right of this, within the bay, is a metal-sheeted door and a former window opening blocked in breeze block with sill remaining. The second floor level of the bay contains three former window openings, blocked as before. The third floor level has a former window opening to the left and two windows to the right with eight-pane metal frames. Openings to each floor are directly in line with each other. To the right of the bay, the first floor level has two former window openings with a smaller opening to their right. The second floor level has four former window openings, with three more to the third floor and a window with an eight-pane metal frame to the far right. The east elevation of the roof has three small cast iron skylights.

The building is first cited in the 1911 valuation book and was occupied by Martin, Nesbitt and Irwin from 1914. It is of industrial archaeological interest and is located within a conservation area.
