2 Clarence Avenue, Londonderry

2 Clarence Avenue is a late Victorian end-of-terrace townhouse built in 1900 to designs by Robert Eccles Buchanan, a local architect and civil engineer active in Londonderry between 1887 and the 1920s. It forms the first of a unified terrace of eleven similar three-storey red-brick houses (Nos. 2–22 Clarence Avenue) stepping down the north side of the street on a steep gradient towards the river, within the Magee Conservation Area.

The house is two bays wide and three storeys tall, rectangular on plan with a projecting rear return at half-landing level. It displays an Arts and Crafts influence, expressed through half-timbered gables, stained leaded glass upper lights, and cantilevered square bay windows supported on large timber brackets with carved timber corbels.

The principal south-facing elevation is laid in Flemish brick bond. To the right, a two-storey canted bay rises through the ground and first floors, surmounted at second-floor level by a rectangular gabled bay cantilevered on large timber brackets with carved timber corbels to either side. This upper gable features vertical half-timber panelling and a plain wide painted timber fascia board above the window head, which contains a pair of 1-over-1 timber sliding sash windows. The casement windows to the canted bay below have stained leaded glass upper lights. All openings are square-headed. The entrance doorway has a moulded cornice supported on console brackets set on moulded pilasters to either side, enclosing a four-panel fielded timber door with a stained glass fanlight above. A single casement window with a stained leaded glass upper light sits above the door opening at first-floor level. At second-floor level there are 1-over-1 timber sliding sash windows. A painted rendered band runs continuously across the ground and first-floor window heads, with a contrasting painted continuous sill course at first and second-floor levels.

The west gable elevation is of exposed brick, abutted by a plain rendered return. Centred on the gable at each floor level is a 1-over-1 sliding sash window; those at first and second floor have coloured margin panes. An additional casement window with a stained glass upper light sits to the left at first-floor level. A continuous painted rendered sill course and a painted rendered band to window heads run across all three levels at ground and first floor. The upper section of the gable has unfinished render, finished with a plain wide painted timber fascia board on corbel brackets. The three-storey rear return is lower on its west side, with a pair of timber sliding sash windows at first-floor level and a single sliding sash at second floor. The east side of the house is abutted by the adjoining No. 4 Clarence Avenue.

The north rear elevation is three storeys tall with a two-storey rear return at half-landing level, finished in painted render, with a door opening onto the rear yard. The fenestration here is irregular, with a mix of 2-over-2 timber sliding sash and casement windows. The rear return has uPVC guttering and downpipe.

The roof is pitched and covered in natural slate with black clay ridge tiles. A large red-brick chimney stack rises from the east side, centred on the ridge and fitted with clay pots. The rear return has artificial slates and a smaller red-brick chimney centred on its gable end. Cast-iron guttering and circular downpipes serve the front elevation.

Although some of the original sash windows to the front have been replaced, the overall style and character of the house remain intact. Conservation works carried out in 1985–86 included re-slating the roof in natural slate, restoring the red-brick chimney stack, and overhauling the rainwater goods.

The house is set back from the pavement behind a low red-brick wall with a painted capping stone, with a small front garden. To the rear, the yard is bounded to the north and west by rubble schist stone walling — which adds further character — with a sheeted timber gate within a square-headed opening to the west, backing onto a shared alleyway with the university campus beyond.

Clarence Avenue was laid out in 1897 and named in memory of Prince Albert Victor, the last Duke of Clarence and son of King Edward VII, who died in 1892 aged 28. The terrace on the north side of the street (Nos. 2–22) was erected in 1900. Its construction formed part of the broader northward expansion of Londonderry, which had begun in the mid-19th century with Georgian-style terraces on Great James Street, Queen Street and Clarendon Street, and which accelerated during a period of economic growth lasting from the 1860s to the end of the 19th century. From the 1880s, new red-brick dwellings at College Terrace and Clarence Avenue were built to house students and staff of Magee College. Buchanan was also responsible for other domestic commissions across the city and for church work, including repairs to St Columb's Cathedral in 1911.

No. 2 was originally valued at £24 and was first owned and occupied by Martha Hamilton, a National School teacher, who lived there until the 1920s. The 1901 Census recorded it as a first-class dwelling of ten rooms. Hamilton died in 1924 and the house remained in family ownership; by the end of the Second General Revaluation of Property in Northern Ireland (1956–72) the valuation had risen to £38, with the Hamilton family still recorded as owners in 1972. The terrace was listed in 1979 and incorporated into the Magee Conservation Area in 2006. Contemporary architectural opinion has praised Buchanan's terrace as "excellently modelled" and "very unified architecturally and virtually intact," with the Conservation Guide describing the dwellings of Clarence Avenue among "the city's architecturally finest and grandest townhouses."
