78 Castle Street, Banff

78 Castle Street in Banff is a house built around 1830-1840, likely on an earlier site. It is a two-storey, three-bay structure with harled walls and painted margins and dressings. The central entrance features a shallow corniced doorpiece with plain anthemion detailing and a panelled door. The windows are arranged regularly, with smaller first-floor windows linked by a continuous sill or bandcourse and an eaves course. The house has 12-pane timber sash and case glazing. There is an additional doorway to the left of the main entrance that leads to a former shop.

At the rear, there is a single-storey, four-bay cottage made of whitewashed rubble, which now serves as a store and has a corrugated iron roof.

Inside, the staircase has plain wooden balusters and a polished wooden handrail. The first-floor drawing-room features deep corniced skirting boards, a black-painted earlier 19th-century chimneypiece, and a later 19th-century cast-iron hearth. There is also a small re-used chimneypiece decorated with the Prince of Wales feathers in a ground-floor room, which was installed in 1990.
