Description
16 St Mary Street is a Georgian house and shop, now used as offices with an apartment above. The walls are rendered and painted, topped with a slate roof. The building consists of three units. On the left, there is a single-storey shop window next to an arched doorway, with a first floor that features a hipped roof set back at an angle. In the center, there is a three-storey single window range that curves to fit the corner; the roof is set back behind a parapet with a scalloped lead cornice. This section has 8-pane sash windows set in reveals and a ground floor shop window, which is framed by fluted pilasters. On the right, facing Upper Church Street, is a two-storey range with a hipped roof, featuring two sash windows on the first floor and a large 19th-century 12-pane shopfront. This shopfront has decorative pilasters, a bracketed hood, and a wide panelled door with a divided overlight, providing access to the dwelling on the upper floors.
