31 Clarendon St., Londonderry

31 Clarendon Street, Londonderry

A mid-terrace two-bay three-storey townhouse with attic, built in 1862 of red brick in Georgian style. It forms part of a row of twelve similar mid-Victorian houses (Nos. 29 & 33-51 Clarendon Street) lining the south side of Clarendon Street. The building is rectangular on plan with a projecting rear return.

The principal elevation faces north onto Clarendon Street, set behind a low rendered wall surmounted by black painted replacement metal railings. The pitched natural slate roof has black clay ridge tiles and a pitched roof dormer to the front. A large rendered chimney stack rises from the east side, centred on the ridge with seven clay pots. Cast-iron guttering and circular downpipes serve the front elevation.

The north-facing front elevation is built of Flemish bond brick with a rendered plinth. The entrance doorway has a three-centred arch opening with a moulded surround to the right, featuring a recessed moulded cornice supported by Doric order columns on either side. The door itself is painted timber, four-panelled, and surmounted by an Adam-style fanlight. All window openings are square-headed with painted cement rendered reveals and painted sills. All windows are 6/6 timber sliding sash except where otherwise noted. A single window sits to the right of the door, with two windows to each of the first and second floors (these upper windows are not aligned with the ground floor opening). A narrow pitched roof dormer is centred on the elevation and contains a 6/3 timber sliding sash window.

The east and west elevations are abutted by the adjoining buildings at Nos. 29 and 33 Clarendon Street respectively. The south (rear) elevation is brick-built, three storeys with attic. A brick pitched roof three-storey rear return projects to the left, abutted by a modern pitched roof two-storey brick extension and further abutted by a modern mono-pitched roof brick single-storey extension. The right bay of the main block comprises a single 6/6 timber sliding sash window to the ground floor, a single three-pane timber casement window to the first floor, and a single 6/6 timber sliding sash window to the second floor. The left bay is abutted by the rear return; its exposed section has a 3/3 timber sliding sash window. The three-storey rear return's south gable is abutted by a modern two-storey and single-storey brick extension with timber casement windows; the exposed section has a single 6/6 timber sliding sash window at first floor level. The east and west faces of the rear elevation were not fully viewed at survey.

A two-storey mews building stands to the rear, rendered with a natural slate roof and clipped eaves. Its north face has three 6/6 timber sliding sash windows to the first floor and a 6/6 timber sliding sash window to the ground floor directly below the middle first floor window (the remainder of the ground floor was not viewed at survey). The east (gable) face is abutted by the mews building of No. 29 Clarendon Street; the exposed section is blank. The west face is fully abutted by the mews building of No. 33 Clarendon Street. The south face has a modern flush fire door to the far right and two blind former window openings to the left, with three blind former window openings to the first floor aligned over ground floor openings.

The property is located within the Clarendon Street Conservation Area, with a small enclosed yard to the rear bounded by the two-storey mews building to the south. Roofing materials include natural slate, cast-iron guttering to the north and uPVC to the south. Walling is brick throughout, and windows are timber.
