4 Coastguard Cottages, Causeway View Lane, Portrush, BT56 8DA

This is a two-storey mid-terrace house, part of a former Coastguard station built in 1896. The entire station complex comprises a detached two-storey station building (the commander officer's house), six two-storey dwellings arranged in terrace form of which this is one, original outhouses, and a later boathouse with associated store. The buildings are designed in a simple, loosely Georgian style and were probably originally finished in brick but are now almost entirely rendered. The complex occupies an urban site north of Portrush town centre, on a slight rise between Main Street to the south and Causeway View Lane to the north.

The terrace (numbered 1-6 Coastguard Cottages) runs north-south, with the former station building at 130 Main Street positioned at the south end of the site. Cottages 3-4 and 5-6 are paired with mirrored internal layouts and identical accommodation. Cottages 1-2 are also paired with mirrored layouts but are slightly larger, reflecting the status hierarchy: the station commander occupied No. 130, middle-ranking officers occupied Nos. 1-2, and junior staff occupied Nos. 3-6. This house sits mid-terrace immediately north of No. 3.

The front façade faces east, accessed via a communal yard. The pitched roof is finished with natural slate and grey fireclay ridge tiles, with overhanging eaves displaying exposed rafter tails. Rainwater goods are uPVC. A shared rendered chimneystack runs to the ridge, decorated with corbelled bands and unmatched clay pots. The west façade is rendered on a rubble stone plinth. The front east façade retains its original red clay brick facing. Windows throughout are flat-headed with 1/1 timber-sash frames, informally arranged on both west and east facades. To the first floor west façade are two windows—the larger on the right, the smaller on the left. The ground floor west façade originally had one window on the right side, later converted to a glazed panelled door. A single-storey projecting lean-to porch extends from the rear west façade, featuring a timber-sheeted door on its south face and a small flat-headed top-hung timber window on its east side.

The gardens extend to the west. To the east are two communal access yards separated by a masonry wall: the northern yard serves the front entrances of Nos. 3-6, while the southern yard serves the rears of No. 130 and Nos. 1-2. To the rear of Nos. 3-6 stands a small range of single-storey outbuildings containing a communal washhouse and two small outhouses per dwelling (one an outside WC, the other a fuel store).
