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

This is a one-and-a-half-storey, two-bay Victorian terraced house built around 1872–74, likely designed by architect William James Watson. It is built of red brick with blue brick and red sandstone dressings, and forms part of a terrace of six similar houses (references HB16.06.038A, B, D, E and F) 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 parking area bounded along Horner's Lane by a random-coursed rubble stone wall with rock-faced coping. A vehicular entrance to the east provides access to the parking area. The dwellings are grouped in symmetrical pairs, each pair sharing a dormer with its neighbour.

The principal south-east facing elevation features recessed semi-circular headed doors at the centre of each pair of houses. Open porches formed by continuous over-sailing eaves are supported on decorative timber brackets. These porches are flanked by narrowly projecting gabled bay windows on each side. Each pair of houses shares a dormer at roof level, with each dwelling having a single small window to the shared dormer. Red and blue brick chimneys of rectangular section stand at apex level above the shared dormers.

The walling is generally laid in English Garden Bond using red brick with a red brick plinth. Single courses of blue brick run at window cill and impost levels. Stop-chamfered brick detail is used to door and window jambs. The window openings are square-headed, with red sandstone heads to the front elevation windows and splayed red sandstone cills. Typically, the windows are top-opening timber casement windows. The pitched front roof is tiled with fibre cement, topped with angled black clay ridge tiles. A flat felt-covered dormer extension roof extends north-west from the ridge to the rear wall of the original dwelling, added around 2009.

A rectangular-section red brick chimney to the north-east side (rebuilt around 2004) has nine courses of blue brick to its top half and two terracotta clay pots. The eaves are narrowly projecting with exposed painted timber rafter ends. Cast iron rain-water goods with half-round guttering discharge to circular section downpipes on the front elevation; the rear elevation and return have uPVC rain-water goods.

The front door is of painted sheeted timber with brass furniture, opening onto the open porch from a concrete platform accessed by a granite step from the shared gravelled yard. The porch is framed with painted timber posts supporting decorative trefoil brackets. The dormer window, centred above the paired porches, contains a small side-opening timber casement window. The gabled, narrowly projecting bay window to the north-east side of the porch contains a paired top-opening timber casement window at ground-floor level, with a sandstone head and a semi-circular red sandstone arch above it. The spandrel panel features herringbone pattern brickwork.

To the south-west, the building is attached to No. 4 Brick Row. Access to the rear north-west facing elevation is limited, but it features a full-width dormer room extension at first-floor level with vertically sheeted timber cladding and a flat felt-covered roof. A single-storey rendered flat-roofed rear return extends north-west from the main house to meet the boundary with a shared rear access passage. A narrow concrete yard lies to the south-west side of the rear return. A painted panelled timber door with two glazed sections to its upper half and an attached window open into the yard from a recessed bay of the return. Two three-part timber casement windows also open from the return into the yard. A smooth rendered modern dwarf wall forms the south-west yard boundary, adjoining No. 4 Brick Row. The rear elevation is clad with varnish-stained timber sheeting at first-floor level and smooth cement render walling at ground-floor level, with slim concrete cills. The dormer contains two timber casement windows at first-floor level looking onto the flat roof of the single-storey rear return. To the north-east, the building is attached to No. 2 Brick Row.

No. 3 Brick Row forms part of the Brick Row terrace within the Rostrevor Conservation Area. The site is bounded to the front by rubble stone walling and to the rear by a high stone retaining wall. The rear facades along Brick Row have been much altered with various extensions of different shapes and sizes. Two-and-a-half-storey red brick semi-detached dwellings are located on a raised site at the south-west end of Brick Row and show some similarity to Brick Row but are considerably larger with significant differences in architectural detail.
