12 De Burgh Terrace, Academy Road, Londonderry

12 De Burgh Terrace is a late-Victorian mid-terraced townhouse built around 1889, forming part of a uniform row of seventeen similar houses on the north side of De Burgh Terrace, Londonderry. It sits within the Clarendon Street Conservation Area and, together with the adjoining listed buildings in the terrace, carries significant group value, making it among the most important buildings within the conservation area.

The house is two bays wide, two storeys tall with a dormer attic, and is built in red brick in a Georgian style. It is rectangular on plan with a projecting rear return. The principal elevation faces south onto a long, sloping raised garden.

The south-facing front elevation is laid in Flemish bond red brick with a painted rendered plinth. At ground floor level there is a canted bay with square-headed painted 2/2 sliding sash windows featuring horizontally divided panes and ogee horns. The entrance doorway sits within a segmental arched opening with a moulded cornice supported by scrolled console brackets with acanthus leaf detail on pilasters. The doors themselves are painted three-panel double-leaf timber, with a plain fanlight above. At first floor level the windows are segmental-headed painted 2/2 sliding sash, with coupled windows positioned above the bay and a single light above the doorcase. A continuous projecting sill course runs across the first floor. The second-floor dormer, situated above the bay, contains a pair of round-headed painted 1/1 sliding sash windows and is finished with a decorative bargeboard. The main roof has bracketed eaves. The pitched, slated roof carries a large brick chimney stack rising from the east side, centred on the ridge, with six clay pots. Clay ridge tiles finish both the main roof and the front dormer. Cast-iron guttering and a circular downpipe serve the front elevation.

The boundary to the south is formed by a red brick wall, rendered with a concrete coping, painted, with a metal gate also painted.

The north elevation, facing the rear yard, is rendered and painted. It includes a three-storey rear return and a large square-headed dormer to the east side. The ground floor has a 6/6 timber sliding sash window, with 2/2 timber sliding sash windows at first and second floor levels. The dormer windows and a later flat-roofed single-storey extension to the rear return are fitted with modern uPVC casement windows, which detract somewhat from the overall character. The north boundary of No. 12's rear yard is defined by a random schist stone wall with a large opening fitted with timber sheeted doors across at least half its width. This wall is surmounted by a modern timber fascia and two or three rows of fibre cement slates forming a miniature pitched roof, hipped at either end. The schist stone wall returns along the east boundary of the yard and is whitewashed. Access to the rear yard is from a shared lane running the length of the terrace.

The east and west sides of the house abut the adjoining properties — No. 11 and No. 13 De Burgh Terrace respectively.

Despite the square dormer, flat-roofed rear extension and uPVC windows to the rear, the exterior has largely retained its character, style and proportion. The plan form is substantially intact, and much of the original internal fabric survives, making this a fine example of its period.

The terrace has a well-documented history. A town plan valuation of around 1873 records that De Burgh Terrace was originally laid out in the 1870s, at which time the street was unnamed and contained no buildings. Construction of the first houses did not begin until 1889. The terrace was part of a broader northward expansion of Londonderry — following the establishment of Georgian-style terraces along Great James Street, Queen Street and Clarendon Street during the 1830s to 1860s — as the city's professional and merchant classes spread out from the Walled City. That northward expansion had been constrained by the walls of the Lunatic Asylum, prompting the development of new terraces to the north-west, on elevated sites overlooking the River Foyle. Crawford Square was laid out in the 1860s to 1870s, followed by Nos 1–17 De Burgh Terrace. Architectural historian D. Calley has described the development of large terraces around a central garden or square as the city's delayed response to Dublin's garden squares, providing a green oasis for wealthy residents near the city centre.

The entire terrace of seventeen uniform two-and-a-half-storey, two-bay houses was developed by Ulick James Daly, a civil servant and gentleman who resided at Eccles Street in Dublin. Daly originally submitted plans for eighteen houses in 1888, but only seventeen were ever built. Construction proceeded in stages between 1889 and 1894, with Nos 1–8 completed first. Most of the completed houses were subsequently leased by the Daly family. Annual Revisions records indicate that Nos 11 and 12 De Burgh Terrace were constructed in 1892–93 and valued at £15 each — £1 higher than Nos 1–8, as they contained an additional room.

The houses were designed as residences for the city's professional and merchant classes. The first recorded occupant of No. 12 was William Beatty, a local baker, who lived there until his death in 1910. The Census Building Return of 1911 described No. 12 as a first-class dwelling containing eleven rooms. The Daly family continued to own the property until at least the end of the Second General Revaluation of Property in Northern Ireland, which concluded in 1972, by which time the house had been valued at £37.

Nos 1–17 De Burgh Terrace were listed in 1979. The terrace was not included in the Clarendon Street Conservation Area when it was first designated in 1978, but in 2006 the area was extended primarily to incorporate the terrace, designating it an area of special architectural or historic interest, the character of which it is desirable to preserve or enhance.

In 1988, No. 12 underwent a renovation that included reslating of the roof in natural slate, replacement of the ground-floor bay window sash windows, and repointing of the exterior brickwork. Writing in 2013, Calley described De Burgh Terrace as "quite simply delightful," noting in particular that "what makes these particularly fine are the long sloping raised gardens to the front of the houses, which are generally very well maintained with some fine trees."

De Burgh Terrace is accessed from Academy Road, which runs between Rosemount Avenue to the north-west and Northland Road to the south-east. The terrace sits immediately north-west of Londonderry town centre, on the western side of the River Foyle, with Brooke Park located to the south-west.
