1-5 Royal Avenue, Belfast, County Antrim, BT1 1FB

1-5 Royal Avenue is a five-storey commercial building on the southeast corner of Royal Avenue and High Street, Belfast, designed by architect David Salmond and completed in 1881. It forms the southernmost three bays of what was originally a larger ten-bay block (nos 1-19 Royal Avenue, now known as Corry House), and its Italianate style, roofline, rhythm, materials and detailing closely match those of the adjoining building to the north, together forming a coherent and architecturally ambitious presence on one of Belfast's principal Victorian commercial streets.

Nothing definitive is known about David Salmond, though the Dictionary of Irish Architects suggests he may have been a son of Thomas Ross Salmond (1828–1917), engineer to the Belfast Harbour Commissioners between 1871 and 1892, and the engineer responsible for the Alexandra Graving Dock on Queen's Island.

The exterior is faced in painted render with rich Italianate detailing. The principal decorative scheme includes giant half-fluted Corinthian pilasters rising between the second and third floors, rusticated pilasters to the first floor, a bracketed cornice over the third floor, and string courses at first- and second-floor cill level. The third-floor windows are the most elaborate, with reeded stucco sides, foliate brackets, floral roundels and moulded cornices — triangular pediments over the single windows and segmental pediments over the tripartite ones — with a coffered apron to the cills. The second-floor windows follow the same treatment but omit the pediments and cill aprons. First-floor windows have lugged architraves, with the single window matching the more ornate third-floor treatment. Fourth-floor windows are flat-lintelled. The ground-floor fascia and shopfront are modern replacements, and all windows have been replaced with uPVC units. The flat roof and rainwater pipes are not visible from public vantage points.

The west elevation facing Royal Avenue is three windows wide, arranged 1/3/3 bays, with a rounded corner turning south. At the corner, the facade cants outward to form bay windows at first- and second-floor level. A fire escape door is located to the north on the west elevation. The south elevation mirrors the west and includes a bipartite window to the east of the corner bay. The north elevation abuts the adjoining listed building. The rear east elevation on High Street is not visible, being abutted by a modern building.

The building sits within a group of late Victorian commercial properties that together represent the expansion of city centre commerce during the 1880s. Royal Avenue itself was laid out in 1880–81 by surveyor J. C. Bretland, who in the process displaced approximately 4,000 residents and demolished almost all buildings on the predecessor street, Hercules Street. The only surviving pre-1880s structure in the area is the former Provisional Bank of Ireland, which remains set back from the current building line, reflecting the original alignment of Hercules Place. Nos 1-19 Royal Avenue was among the very first commercial properties erected on the newly created boulevard.

The block was designed for John Robb of J. Robb & Co. Ltd., silk merchants, wool drapers and general warehousemen, and was originally intended to connect with Robb's properties on Castle Place. At completion in 1881, nos 1-5 comprised two ground-floor commercial units with offices above. The first ground-floor tenants were Harbinson & Son (likely J. F. Harbinson & Co., jewellers) and Leahy & Kelly, wholesale tobacconists, with the upper offices occupied by a variety of firms. By 1900 the corner unit had passed to A. L. Goodson, mantle manufacturer and furrier, though a valuer at the time described the corner premises as offering very poor accommodation and noted that some upper offices were vacant. In 1901 the Equitable Life Assurance Society of the United States occupied the upper floors alongside several minor solicitors' firms. By 1907 the Berlitz School of Languages Ltd. and F. T. Connell's Civil Service Institute had taken the upper floors, and by 1918 the Civil Service had established a Business Training Institute there. In 1929 the two ground-floor units were combined into a single premises, briefly occupied by D. Lyle Hall, a linen merchant. By the First General Revaluation of Property in Northern Ireland in 1935 — by which time Hall had become recorded owner of the entire nos 1-19 — the ground floor was occupied by Prices (Tailors) Ltd. and the upper floors remained in Civil Service use. Between the 1950s and 1970s the entire building was occupied by Prices (Tailors) Ltd., with the upper floors used for storage and briefly also housing the Loyalist Charity & Benevolent Pool Club between at least 1956 and 1968. A facade restoration was carried out in 1977. The building was listed in 1992 at which time it was known as Corry House. At the time of listing the ground floor was occupied by a Spar convenience store; the use of the upper floors as storage or private offices was unclear.

Although the building has been compromised by modern alterations — most notably the uPVC windows and modern ground-floor shopfront — substantial historic fabric and ornamental detailing survive across the upper floors. The building is a good example of the large-scale Italianate commercial architecture that characterised the development of Belfast city centre in the late Victorian era, and derives additional significance from its group value as part of a unified and coherent streetscape on Royal Avenue.
