55 Rosemount Avenue, Londonderry

A late Victorian end-of-terrace two-storey townhouse with attic, built in 1904 as part of a terrace of five similar properties. The building is constructed of red brick laid in English Garden Wall Bond, with rendered sections to the rear elevation.

The main entrance is positioned at a 45-degree angle on the corner, set two steps up from pavement level. The principal south-east elevation facing Rosemount Avenue features a square bay window with rendered and painted finish, painted cornice and curved pitched roof, alongside two first-floor windows with segmental-arched heads and brick voussoirs. These windows are replacement 1/1 uPVC units with moulded concrete cills.

The roof is pitched with replacement fibre cement covering and black clay ridge tiles. Two modern rooflights are set into this roof. A large red-brick two-stage chimney stack with six terracotta clay pots rises from the north-east side. Stepped dog-tooth red-brick cornicing runs at eaves level with matching detail to the chimney. Replacement ogee aluminium gutters and cast-iron downpipes serve the principal elevation.

A two-storey rear return, built at half-landing height, steps down to a single storey. The north-east elevation displays red-brick walling with two 1/1 uPVC windows at first floor and attic level, both with segmental-arched heads and brick voussoirs. A large chimney surmounts the gable.

The rear return, built in red brick, features two square-headed windows with replacement 1/1 uPVC units and moulded concrete cills. A modern single-storey side extension with red-brick walling in Stretcher Bond adjoins the north-east side, with a lean-to slate roof and doors at either end.

The building abuts No. 57 Rosemount Avenue to the south-west and is located on an elevated site on the north-west side of Rosemount Avenue, overlooking Brooke Park and adjoining Rosemount Factory.
