20 Florence Terrace, Northland Road, Londonderry

20 Florence Terrace is an end-of-terrace three-storey, two-bay rendered Victorian townhouse built in 1874-75, architect unknown. It forms part of a terrace of six similar buildings on the north-west side of Northland Road. Numbers 12-20 were constructed earlier than No. 10 Florence Terrace, which dates to 1890, though all are comparable in form and style.

The building has a rectangular plan facing south-east with a three-storey return to the rear built at half-landing height. The pitched natural slate roof is continuous with the adjoining property, No. 18 Florence Terrace. A small dormer is centred on the front elevation with a single roof light to the left side and two to the right. A large two-stage brick chimney stack with buff clay pots rises from the north-east gable-end elevation. The timber fascia boards feature moulded soffit with paired block modillions. Half-round cast iron guttering and circular downpipe serve the front elevation.

The front elevation displays a single-storey three-sided canted bay to the right of the entrance door, raised on a plinth with segmental arched-headed windows on a sill-course. A deep moulded cornice and parapet above are painted in contrasting colour. All windows are 1/1 double-hung timber sliding sashes with moulded horns. Upper-floor windows have moulded architraves with stop blocks on sills, while first-floor windows feature keystones. The recessed segmental arched-headed door opening, accessed by five steps up, contains a replacement raised-and-fielded four-panel timber door flanked by decorative corbel brackets on plain pilasters supporting a deep moulded cornice and plain fanlight. Low rendered painted walls flank either side of the entrance steps.

The south-west elevation is adjoined to No. 18 Florence Terrace. The north-east gable-end elevation is rendered and painted, with segmental arched-headed 1/1 timber sliding sash windows to the left side on first and second floors. The large two-stage brick chimney stack with five buff clay pots tops this elevation. The rear elevation is rendered and painted with uPVC casement windows and a large slated pitched roof dormer to the main roof. The three-storey return abutting the rear is finished in rough-cast painted render with square-headed uPVC casement windows to all levels on the north-west elevation. The north-east elevation of the return contains timber panelled doors to all levels opening onto a spiral metal fire stair. uPVC rainwater goods serve the rear elevation and return.

The building is located on the north-west side of Northland Road with a tarmac parking area to the front enclosed by a low rendered painted boundary wall. The front elevation faces south-east overlooking Magee University grounds and the River Foyle beyond.
