4 Crawford Square, Londonderry

4 Crawford Square is a three-storey, two-bay rendered Italianate terraced house built in 1871 to designs by Robert Collins, Londonderry's Consulting Engineer from 1866 to 1874. It forms part of an impressive continuous terrace of sixteen buildings on a sloping site to the south-west side of Crawford Square, a mid-Victorian grassed and tree-lined park square laid out in 1861 off the Northland Road, overlooking the River Foyle. The house is listed along with its outbuilding and boot scraper, and has group value with the other listed buildings in the terrace. It falls within the Clarendon Street Conservation Area, designated in 1978.

The house is rectangular in plan, facing north-east, and is paired symmetrically with the adjacent No. 3 Crawford Square. The pitched natural slate roof is continuous with No. 3, and a large rendered chimney stack with buff clay pots is shared with No. 5. The timber fascia and moulded soffit feature paired block modillions, with half-round cast iron guttering discharging to a circular cast iron downpipe on No. 3.

The front elevation is the most architecturally distinctive face of the building. To the right of the entrance is a two-storey, three-sided canted bay window with a parapet, recessed panels between the first and second storeys, and moulded cills and string courses. All window openings have segmental arched heads and one-over-one double-hung timber sliding sash windows with moulded horns. The first-floor window directly above the main entrance has a moulded architrave with stop blocks and a moulded cill shared with No. 3. The entrance itself is set within a recessed arched doorcase with a moulded soffit and a tiled step, containing an original four-panelled door with glazed upper panels and a plain semi-circular fanlight above. The doorcase is topped by a hood mould with a keystone and decorative console brackets.

The rear elevation is also rendered, with square-headed window openings. The first and second floors have six-over-six double-hung sliding sash windows, while the ground floor has a two-over-two sash. The three-storey return to the rear has a hipped natural slate roof with blue-black hip and ridge tiles and a rendered chimney with a moulded corbel, shared with the return of No. 3 Crawford Square. The return features square-headed window openings with six-over-six timber sashes to the upper floors and a glazed door leading out to the rear yard. An attached single-storey brick-built outshot, which does not extend the full width of the return, has a gabled monopitch natural slate roof, a timber bargeboard, and replacement uPVC rainwater goods, a replacement uPVC window, and a timber door to the north-west side. From the rear yard, five steps lead up to a stone-built outbuilding with brick surrounds to its openings and a pitched natural slate roof. This outbuilding forms part of the stepped row of outbuildings associated with the Crawford Square houses that front onto Academy Road.

The main house is set back slightly from the footpath and is modestly elevated above it. It is approached by a shared path and a short flight of stone steps shared with the adjacent property. At the top step sits an original cast iron boot scraper. The front garden is laid out in gravel and enclosed by a hedge. The building faces north-east over the tree-lined green of Crawford Square.

Crawford Square was originally laid out in 1861 by the civil engineer and architect Fitzgibbon Louch (1826–1911), who established an independent practice in Londonderry in 1859 and was also responsible for the entrance to the City Cemetery and the design of the Magazine Gate entrance to the city walls. According to The Dublin Builder, the square was named after Samuel Law Crawford, a local solicitor who owned the land. The square was part of the city's northward expansion following the establishment of Georgian-style terraces along Great James Street, Queen Street, and Clarendon Street during the 1830s to 1860s, and was designed to house Londonderry's professional and merchant classes. At the time the first tenders were invited in the 1860s, the Northland Road was still described as a country road leading from the city towards Donegal. Crawford Square, along with Templemore and Victoria Parks, has been characterised as the city's delayed response to Dublin's garden squares — creating a green oasis near the city centre for its wealthier residents, with an enclosed central garden bounded on three sides by the square.

Nos. 1 and 2 Crawford Square were the first houses to be constructed, erected in 1865 for Samuel Knox, a building contractor, while the majority of the adjoining terrace was built for John McAdoo, a local seed merchant and landowner. No. 4, together with the adjoining Nos. 3 and 5–10, was constructed in 1871. According to The Irish Builder, these eight dwellings were designed by Robert Collins and built by the firm of G. & R. Ferguson. Upon completion, the rateable value of No. 4 was assessed at £36, a figure that remained unchanged through the Second General Revaluation of Property in Northern Ireland (1956–72).

In 1911 No. 4 Crawford Square was occupied by Matthew Robinson, a local architect and engineer who designed the Domestic Science School on the square in 1907 (now demolished) and was elected City Surveyor in 1909. The 1911 Census Building Return described the house as a first-class dwelling consisting of twelve rooms, with a stable as its sole outbuilding. In 1970, the Ulster Architectural Heritage Society guide to Londonderry described Nos. 1–19 Crawford Square as "a fine terrace of three-storey rendered buildings on a sloping surface overlooking a tree-lined grassy square. The houses are well modelled, with two-storey height bay windows." Nos. 1–23 Crawford Square were listed in 1979. Records note that No. 4 underwent internal and external renovation in 2002, which included the replacement of the original roof.
