184 Coast Road, Carnfunnock, Ballygalley, Larne, Co Antrim, BT40 2QG

184 Coast Road, Carnfunnock, is an early Victorian gate lodge built around 1850 in Tudor Revival style. It was designed for James Agnew as a secondary gate lodge to his residence Carncastle Lodge, which stood nearby but was demolished in 1937. The lodge appears on the Ordnance Survey map of 1857 and is historically linked to a main gate lodge at 179 Coast Road.

The building is a one and a half storey structure of symmetrical design on its entrance front, constructed of squared random rubble blackstone with ashlar quoins and moulded dressings in sandstone. The main entrance faces south. The three-bay south elevation features a central entrance within a projecting gabled porch flanked by a window on either side. The doorway is timber, Gothic panelled and new, set within a Tudor arched opening topped by a projecting drip moulding carried on moulded corbels. Above the doorway sits a carved sandstone shield bearing the Agnew arms, set within a gable with shouldered kneelers and an ornate octagonal stone finial with a lozenge-patterned shaft. The porch's side walls contain small rectangular timber casement windows with Tudor arched heads and small panes, set in raised rectangular surrounds. The windows flanking the porch are two-light timber casements with similar detailing, set in rectangular surrounds with projecting Tudor style drip mouldings.

The roofs are laid in Bangor blue slates in regular courses between gable copings of dressed sandstone, with cast iron gutters and downpipes.

The west elevation comprises the main gable of the original lodge with a large modern extension to the left, including a gabled projection, partly hidden behind a basalt wall with rough basalt crenellations. The original gable has stepped kneelers surmounted by an ornate octagonal stone finial on a coved corbel. A three-light window to the ground floor features similar detailing to the entrance front but is divided by stone mullions with Tudor style drip moulding. A Gothic arched lancet window to the first floor has a projecting Gothic drip moulding. The east elevation is similar to the west, with a comparable gable to the original lodge and a modern extension to the right.

The modern extension, approved in 1995, doubles the building's size and replicates some of the lodge's original features using reconstituted stone for dressings, including a new rear gable copied from the main gables and a new chimney based on the original but not exact in detail. It introduces new elements such as shaped timber barge boards and a long panelled and glazed conservatory facing the main road.

The building stands in a rural area on a narrow plot between the main Coast Road and the driveway to a country park, exposed to public view on all sides. A flat lawn extends to its front beyond the front boundary, which is formed by a low wall of boulders surmounted by a fence of vertical boards protecting a low hedge. The boundary curves round the east side to incorporate a pair of square basalt gate piers without gates, and round the west to abut a basalt rubble screen wall with sandstone dressed end, which terminates northward in a wide gateway currently under construction.
