Description

Aberteg, located on Marine Terrace, is a three-storey, two-bay house built in the late Georgian style. It features roughcast walls with rusticated quoin strips and a slate roof with projecting eaves, which is shared with No 6. The house has roughcast end stacks, and the openings are offset to the right side. On the right side, there is a recessed fielded-panel door with an overlight made of coloured frosted glass. The windows are 12-pane horned sashes, located under hood moulds on the lower two storeys, while the upper storey has shorter windows beneath the eaves. Additionally, the left gable end contains a 2-pane sash window positioned in the middle storey on the right side. The property has not been inspected.
