5 Brick Row, Horner'S Lane, Rostrevor, Co.Down

A one-and-a-half-storey, two-bay Victorian terraced house built circa 1872–74, most likely designed by architect William James Watson. The building is constructed of red brick with blue brick and red sandstone dressings. It features an L-plan form with a full-width flat-roofed dormer extension and single-storey return to the rear, added circa 1982 by an unknown architect.

Number 5 forms part of a terrace of six similar houses located on the north-west side of Horner's Lane, off Bridge Street, Rostrevor. The terrace faces south-east and is fronted by a shared gravelled area bounded by a random-coursed rubblestone wall with rock-faced coping. A vehicular entrance to the east provides access to the gravelled parking area.

The dwellings are grouped in symmetrical pairs, each pair sharing a dormer with its neighbour. Number 5 has a recessed semi-circular arched door to the centre, flanked by narrowly projecting gabled bay windows. The open porch is formed by continuous over-sailing eaves supported on decorative timber brackets. Each house has a single diminutive window to its shared dormer, with rectangular-section red and blue brick chimneys at apex level. The gabled bay windows and dormers feature decorative pierced painted timber bargeboards.

The main walling is in English Garden Bond red brick with a red brick plinth. Single blue brick courses run at window cill and impost levels. Stop-chamfered brick detailing appears at door and window jambs. The front elevation has square-headed window openings with red sandstone heads and splayed red sandstone cills. Windows are typically top-opening timber casements.

The pitched natural slate roof of the front block has angled black clay ridge tiles, graded in size with larger slates at eaves level. The flat felt-covered roof of the rear dormer extension has two skylights. A rectangular-section red brick chimney to the north-east side has nine courses of blue brick to its top half and two terracotta clay pots.

The principal south-east elevation features a painted sheeted timber door with black iron furniture opening onto an open porch formed by over-sailing eaves and framed by decorative painted timber posts with decorative trefoil brackets. The door opens onto a concrete platform accessed via a granite step from the shared yard. The dormer window above has a diminutive side-opening timber casement window. The gabled bay window to the north-east of the porch has a paired top-opening timber casement window at ground floor level, with a semi-circular red sandstone arch and herringbone pattern brick spandrel panel.

The north-west facing rear elevation comprises a full-width flat-roofed dormer at first floor level, two bays in width, abutted by a single-storey L-plan flat-roofed return. The single-storey block extends north-west to a shared rear access passage, with a three-part timber casement window to its north-west end. The main building has a top-opening timber casement window at ground floor level to the south-west side. The single-storey return has a painted sheeted timber half-door with black iron furniture and small glazed section, facing into a narrow yard and decked roof terrace with turned timber balustrade and acorn finial newels. The dormer room extension has pebbledash render finish with two openings at first floor level overlooking the roof terrace.

The building is attached to number 4 Brick Row to the north-east and number 6 Brick Row to the south-west. Cast iron rainwater goods with half-round guttering and circular section downpipes serve the main elevation; uPVC rainwater goods serve the rear return.

The site is bounded to the front by rubble stone walling and to the rear by a high stone retaining wall. The rear facades of Brick Row are generally much altered with various extensions of different shapes and sizes. The terrace is located within the Rostrevor Conservation Area.
