Atlantic Lodge, 13 The Promenade, Castlerock, Coleraine, Co Londonderry, BT51 4RF

Atlantic Lodge is a small, compact two-storey red brick villa built in 1882, situated on the south side of The Promenade in Castlerock, overlooking the sea. The building exemplifies the seaside resort villas that developed in this late 19th-century watering place, which grew around the railway halt on the line to Londonderry.

The main house features a shallow pitched pan tile covered gabled roof with side-on chimneys having tall decorative pots. The front elevation faces roughly north and is symmetrical. At the centre of the ground floor is a broad segmental headed doorway with glazed and panelled double doors and a segmental fanlight. To the left and right of this doorway are canted single storey bays, each with large plain sash windows to either side and flat roofs (though these bays appear to have originally possessed hipped roofs). The first floor contains three relatively small segmental headed windows with plain sash frames. The east and west gables each have two windows per floor, all with similar segmental headed sashes arranged symmetrically. On the west gable, the first floor window to the right has been shortened with a recent single pane frame. The chimneys are set side-on close to the centre of the ridge and appear to have been rebuilt in modern red brick, each with four tall decorative pots.

A two-storey rear extension was added in the 1980s, centred on the rear elevation. A single-storey lean-to conservatory is sandwiched between the extension and the adjoining coach house, also covered in pan tiles with a large Velux window. The extension has partly glazed doors and plain sash windows arranged asymmetrically across its east, south, and rear faces.

Attached to the west side of the main house is a small two-storey coach house. Its north gable contains a flat arch vehicle doorway to the ground floor and a small segmental headed sash window. The east elevation has a small sash window to the first floor and a smaller square window below; the left side is in basalt rubble, the right side rendered. The south gable is effectively single storey due to the ground rising dramatically to the rear, with a partly glazed door. The west elevation is rendered to the left and in basalt rubble to the right, with no openings visible. The coach house roof is shallow pitched and gabled, covered in corrugated asbestos.

The property is enclosed by a low basalt rubble wall topped with limestone rubble coping. At the west end is a vehicle gateway with recent timber sheeted gates and modern brick pyramidal capped piers. A taller wall of matching materials runs along the west side. The garden extends around the front, east side, and rear of the house. Recent alterations include PVC rainwater goods, roof replacement, rebuilt chimneys, and the substantial rear extension. The cumulative effect of these alterations and repairs over recent decades has resulted in the building falling below the quality deemed necessary for listed status.

The house was built in 1882 by Samuel McCrory, probably as a seasonal residence. It was originally approached by a drive to the rear off Main Street; The Promenade only became a throughfare in the mid 1900s. Henry Connell acquired the property in 1906, and he may have given it the name Atlantic Lodge, which does not appear in directories prior to that date.
