10 Florence Terrace, Northland Road, Londonderry

10 Florence Terrace is a three-storey Grade B1 listed building over a basement, built in 1890 to designs by architect William Barker. It is a five-bay rendered Italianate-style end of terrace house located on the north-west side of Northland Road in Londonderry, on an elevated site. The building was constructed later than the adjoining five terraced houses (which date from 1875), and differs in form and style from its neighbours.

The house has a rectangular plan form facing south-east, with a large double-pile three-storey return to the rear, now adjoined by a large modern L-shaped two-storey rendered extension.

The hipped natural slate roof has black clay ridge tiles and four large two-stage brick chimneys with buff or terracotta clay pots. Timber fascia boards and moulded soffit with paired block modillions run along the eaves; cast iron rainwater goods serve the main house throughout.

The front south-east elevation features a single-storey three-sided canted bay to the left of the door opening and a square bay window to the right. Both bays have parapets with cut-outs containing decorative ironwork, deep projecting cornices below, and moulded sill-courses. The bay windows have square-headed 1/1 timber sliding sashes. Upper-floor windows are segmental-arched headed with 1/1 double-hung timber sash windows with moulded horns. First-floor windows have moulded architraves with keystones on a continuous sill-course; a continuous moulded string-course runs between the first and second floors. Diamond-cushioned quoins frame either end of the elevation.

The recessed semicircular arched door case is the centrepiece, with a hood mould with keystone and moulded pilasters either side featuring egg-and-dart detailing to the archivolt and crown moulding. Four concrete steps rise to two-leaf timber doors with diamond raised-and-fielded panels and a plain semi-circular fanlight above. An original letter slot survives in the inner porch door.

The south-west side elevation is rendered in painted finish and is abutted by a painted metal external fire stair. It has a moulded sill-course to the first-floor windows and a moulded string-course below the second floor. Diamond-cushioned quoins mark the corners of both the main house and rear return. Ground and first-floor windows have moulded architrave surrounds with keystones; ground-floor windows are square-headed while first and second-floor windows have segmental arched heads. All windows here are 1/1 timber sliding sashes. At second-floor level, a timber fire door opens onto the metal external staircase.

The rear north-west elevation is rendered and contains square-headed window openings with uPVC casement windows. A large semicircular arch-headed 1/2 timber sliding sash window with horns and coloured glass sits at the second-floor half-landing level, with margin panes. A small circular window sits between two right-side bays at second-floor level.

The three-storey return has a double-pile hipped natural slate roof with black ridge tiles and two brick chimney stacks. The rear elevation is abutted by a high stone wall and a square pier to the south end.

The principal entrance to the main house is approached by a short flight of concrete steps with a low concrete wall and pier to either side. The front and driveway are finished in bitmac and enclosed by a dwarf wall. The north-east side of the house adjoins No. 12 Florence Terrace. A large modern extension adjoins the rear of the building.
