33 Aberfoyle Terrace, Strand Road, Londonderry, Co. Londonderry, BT48 7NP

No. 33 Aberfoyle Terrace is a mid-terrace two-storey-with-attic red brick townhouse, completed in 1911 as part of the final phase of a row of seventeen similar houses built along the west side of Strand Road over two decades from 1891 to 1911. The terrace was designed by William A. Barker (1851–1898), a local architect and engineer who played a significant role in developing the university area of Londonderry in the 1890s. Barker died before the terrace was finished, having completed only roughly half of the row by the time of his death. No. 33, together with the adjoining No. 35, was the last pair to be built. The house is rectangular on plan with a projecting large rear return and extension, and sits behind a painted low brick wall with metal railings, set back from the pavement of Strand Road with the River Foyle to the east and the campus of Magee College (University of Ulster) rising immediately to the rear to the west.

The principal east-facing elevation is laid in Flemish bond red brick with yellow brick dressings and a projecting brick cornice at eaves level, giving the facade its characteristic polychromatic character. At ground floor right there is a canted single-storey bay, all in brick that has been painted in a contrasting colour. A continuous sill course spans the full width of the elevation at first floor level. Window openings to the canted bay and first floor are segmental arch-headed; above, a round-headed opening serves a wall-headed gable half-dormer window with a painted apex fascia board. Glazing throughout consists of 1-over-1 timber sliding sashes to the canted bay, with casement windows at first floor and dormer level. The entrance doorway has a segmental arch-headed opening approached by three steps up from the pavement, with terracotta tiles to the steps; the door itself is a painted six-panel fielded timber door with a plain fanlight above. The north and south sides are abutted by the adjoining Nos. 31 and 35 Aberfoyle Terrace.

The rear west elevation is two storeys, with a large-scale two-storey rear return abutted by a two-storey extension spanning the full width and length of the rear yard and abutting the rear boundary wall. The fibre cement slated pitched roof carries black clay ridge tiles to the main roof, the rear return, and the rear extension. A large polychromatic brick chimney stack rises from the north side of the principal elevation in two stages, while a further large polychromatic brick chimney centred on the rear ridge has circular clay pots. Rainwater goods to the front elevation are cast iron.

The terrace was built on land belonging to John McFarland, a local magistrate and engineer who lived at Aberfoyle House on the hill above Strand Road, from which the terrace takes its name — it was originally known as Templemore Terrace, with the name changed to Aberfoyle in around 1903. Barker was also responsible for Florence Terrace on the Northland Road, a Professor's House within the Magee Campus, and was associated with the layout of Foyle College grounds for building purposes.

No. 33 was originally valued at £17 and was first occupied by a Mr. James Tees, who continued to live there until 1940. The First General Revaluation of Property in Northern Ireland (1936–57) raised the value to £27 and recorded a Ms. Mary Piggott as the occupant; the Piggott family continued to reside there until at least the 1970s. The Second Revaluation (1956–72) noted that the McFarland estate retained ownership throughout that period and recorded the value as rising to £30 by 1972. The dormer window was replaced in around 1982, and the roof was reslated in natural slate in 1985. The building was converted into a bed and breakfast hotel in the 1980s, and a three-storey rear extension was added in around 1998. The painting of the brickwork to the ground floor bay and around the front door is noted as a detraction from the building's character, though the front facade otherwise retains its historic polychromatic brick detailing.

Nos. 3–35 Aberfoyle Terrace were listed in 1979 and incorporated into the Magee Conservation Area in 2006. The whole terrace shares group value and contributes to the character of the conservation area through its late Victorian and Edwardian detailing and form. The Conservation Guide for the area describes the terrace as one of five zones of distinct character within the Magee Conservation Area, while noting that it appears somewhat isolated on the Strand Road, now bordered by four lanes of fast-moving traffic.
