8 Clarence Avenue, Londonderry

No. 8 Clarence Avenue is a mid-terrace, two-bay, three-storey red-brick townhouse in the Arts and Crafts style, built in 1900 to designs by Robert Eccles Buchanan, a local architect and civil engineer who was active in Londonderry between 1887 and the 1920s. It sits on the north side of Clarence Avenue within the Magee Conservation Area, in the townland of Edenballymore, and forms part of a unified terrace of eleven similar houses that step down the hill towards the river (Nos. 2–22 Clarence Avenue). The avenue itself 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 southern terrace (Nos. 1–17) was built in 1899–1900, while this northern terrace was erected in 1900. Buchanan's authorship is confirmed by a report in the Irish Builder of 15 January 1900.

The house is rectangular on plan with a projecting rear return built at half-landing level. The principal, south-facing elevation is laid in Flemish brick bond and is two bays wide. 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 that is cantilevered on large timber brackets with carved timber corbels to either side. The gable is decorated with diagonal half-timber panelling and finished with a plain wide painted timber fascia board. All openings are square-headed. The entrance doorway is reached by five steps and features a moulded cornice supported on console brackets, with moulded pilasters to either side framing a pair of fielded-panel timber half-leaf doors with a plain fanlight above. The windows throughout are timber casements, with stained glass upper lights to the canted bay on the ground and first floors and to the window above the door at first-floor level. At second-floor level the windows are timber sliding sash. A painted rendered band runs across the ground and first-floor window heads, and a painted sill course runs at first and second-floor window levels.

The roof is pitched and covered in natural slate with terracotta clay ridge tiles to both the main roof and the rear return. A large red-brick chimney stack with a dog-toothed corbel course rises from the east side, centred on the ridge and fitted with clay pots. A small red-brick chimney also rises from the gable end of the rear return. Rainwater goods to the front elevation are cast-iron guttering with circular downpipes; uPVC is used to the rear.

The north elevation is of three storeys, with the two-storey rear return finished in smooth painted render. The rear yard has been infilled with a modern single-storey extension, added around 2009 to provide additional living space and a ground-floor bathroom, with a lean-to roof covered in artificial slates and a polycarbonate domed skylight, and cement-rendered walls. Fenestration to the rear is irregular: the upper floors have 2-over-2 timber sliding sash windows, the rear return has timber casements, and the modern extension has uPVC casements and double doors. The rear yard is bounded by modern concrete block walling with a precast concrete coping and a metal-sheeted gate within a square-headed opening, backing onto a shared alley with the university campus beyond.

The sliding sash windows to the principal elevation have been replaced, but the stained glass upper lights survive. A single-storey extension exists to the rear. The roof was reslated in second-hand slate during conservation work carried out in 1986.

The house is set back from the pavement behind a low red-brick wall with a small front garden. The east and west sides abut the adjoining properties, Nos. 6 and 10 Clarence Avenue. Each house in the terrace retains its ornate doorcase and canted bay, with alternating diagonal and straight half-timbered gables to the cantilevered square bays above, giving the row a highly consistent and well-articulated character that has been praised by commentators as "excellently modelled" and "virtually intact."

When first built, No. 8 was valued at £24. The 1901 census described it as a first-class dwelling of eight rooms, initially occupied by Robert H. Algeo, a local accountant, whose family continued to live there until the 1970s. By the First General Revaluation of Property in Northern Ireland (1936–57) the value had risen to £32, with ownership recorded under a Mr James A. Thompson from at least the 1930s; by the end of the Second Revaluation (1956–72) the value had risen further to £39. The terrace was listed in 1979 and incorporated into the Magee Conservation Area in 2006.

The development of Clarence Avenue took place against a backdrop of northward urban expansion in Londonderry. Georgian-style terraces on Great James Street, Queen Street and Clarendon Street had initiated this growth from the mid-19th century, and the Victorian terrace at Crawford Square followed in the 1860s–1870s, at a time when the Northland Road area was still largely rural in character. A sustained period of economic growth from the 1860s to the end of the 19th century drove the city's continued expansion, culminating in the development of the Magee College campus and the construction of new red-brick dwellings at College Terrace and Clarence Avenue from the 1880s onwards to house students and college employees. The Conservation Design Guide for the Magee Conservation Area identified the dwellings along Northland Road, Lawrence Hill, Springham Street and Clarence Avenue as representing some of the city's architecturally finest and grandest townhouses, singling out Clarence Avenue in particular as a terrace that is very unified architecturally and virtually intact. Buchanan himself was also responsible for other domestic work across the city during this period, as well as church alterations including the repair of St Columb's Cathedral in 1911.
