A stone cornice runs below the parapet, which has coping, and there are cast iron area railings. The flank wall has revealed sash windows along with some blind windows. The entrance consists of a semicircular arched doorway with a fanlight.

Inside, the house includes some panelling, a dog leg staircase, and a late 18th century cornice. Additionally, there is a wall-mounted Windsor gas lantern above the northernmost ground-floor window on the west elevation.
