Description
The former Fog Station includes the former keeper's house and enclosure walls, consisting of two buildings situated within a walled enclosure. The northernmost building is the compressor house of the fog station, which features lined-out render over rubble, painted white. It has a flat roof that is set behind a moulded cornice and blocking course. This single-storey building has a doorway to the left of centre on the west-facing elevation, which consists of a plank door with a narrow over light, flanked by transomed windows. The south elevation has wide double doors leading to the engine room, with similar flanking windows. Fog horns are mounted on the roof, originating from a metal drum.
Adjacent to the compressor house is the former lighthouse-keepers' cottage, built in a similar style with lined-out render and a flat roof behind a moulded cornice and blocking course. The cottage features a porch that projects from the west elevation and has three-window return elevations. The enclosure walls, which also define the gardens of the dwelling, are made of roughly rendered rubble with segmental copings.
