21 Windsor Hill, Newry, Co Down, BT34 1ER

21 Windsor Hill is a one and a half storey red brick house with a two-storey octagonal tower, situated on the corner of Arthur Street and Windsor Hill in Newry. The principal gable faces Windsor Hill. The building dates to the 1890s and was erected by Alexander Whelan, a well-known Newry building contractor, at the same time as the adjacent properties at nos 17 and 19 Windsor Hill. It first appears as vacant in the 1895 Valuation Book and was occupied the following year.

The main roof is gambrel with natural slates and scalloped terracotta ridges, overhanging eaves and exposed rafter tails. The two-storey octagonal tower abuts the left of the facade and has a steep natural slate roof with a wrought iron crown finial and exposed eaves. A decorative gable dormer projects from the front right, with an A-framed fretted timber bargeboard. Two chimneys rise from the gables, both with partly rebuilt red brick stacks. The walls throughout are red brick laid in English garden wall bond.

A single-storey red brick porch with pitched natural slate roof, terracotta ridge and decorative bargeboards abuts the ground floor right. It contains a semicircular headed opening with a wrought iron gate, with the right cheek blank and the left cheek featuring two openings separated by a stop end chamfered brick pier. All windows are 1/1 top-hung plastic units set within chamfered openings, with granite cills and segmental heads. The tower has three windows at ground floor (one per cant) and four above. The left elevation along Arthur Street comprises the tower at right and a single window at left. The rear features a single-storey return with monopitch natural slate roof and a pair of windows to the upper floor of the main block.

The small front garden is enclosed by a granite chamfered base and mature hedge. The rear garden is enclosed by a coursed granite rubble wall with rock faced copings and a large sheet metal sliding door. The interior is largely original. This is a substantial late Victorian suburban residence with good brick and terracotta detailing, though of relatively late date and not of special architectural or historic interest.
