59 Clarendon St., Londonderry

59 Clarendon Street, Londonderry is a Victorian mid-terraced three-storey townhouse over basement, built around 1872. It is constructed of painted render and brick, rectangular in plan with its principal elevation facing north. The building was constructed as part of a row of four terraced houses arranged in two pairs, with No. 59 paired with No. 61. It stands within a terrace of ten similarly scaled townhouses lining the south side of Clarendon Street.

The principal north elevation has painted render to the ground floor and Flemish brick bond above to the upper floors. The ground floor features a round-arch opening to the doorway, accessed by four steps up from the pavement, and 1/1 sliding sash timber windows with bull-nosed cills and moulded apron panels below. A shoulder-course divides each window. A hood mould and flying keystone mark the composition. The entrance door is painted timber with four panels in a diamond pattern and has a plain fanlight above. The first floor has square-headed 1/1 sliding sash windows with a painted masonry cill-course, while the second floor has segmental-arched 1/1 sliding sash windows. A small dormer contains a round-arched window. The basement level has squared-headed timber top-hung casement windows.

The front boundary comprises a low rendered wall topped with sandstone coping and ornate cast-iron railings painted black, which enclose the basement level.

The east and west sides are abutted by adjoining buildings at Nos. 57 and 61. The south elevation is rendered but unpainted, with a three-storey rendered rear return at half-landing level. A square-headed door within the east face of this return discharges onto an external galvanised steel escape stair. Windows visible on the main south elevation are 6/6 sliding sashes; the return has a mix of casement and timber sliding sash windows.

The roof is pitched slate with black clay ridge tiles. A large red-brick chimney stack, which has been rebuilt, rises from the east side centred on the ridge with nine clay pots. Polychromatic brick detailing is present at the eaves. Cast-iron guttering is supported on corbel brackets with a cast-iron downpipe to the front elevation.

At the rear boundary, a one-and-a-half storey duo-pitched rubble schist stone outhouse spans the width of the yard. It has a slate roof with black clay ridge tile and clipped eaves, and uPVC guttering. The south elevation, which opens onto a shared alley, is informally arranged with one square-headed window opening set almost centrally just below eaves level and a square-headed door opening to the right containing a sheeted timber door. Red brick patch repair is evident around this doorway.

The property is located within the Clarendon Street Conservation Area, just above the junction of Clarendon Street and Princes Street.
