Description
4 St Mary Street is a former house that has been converted into a shop with accommodation above. The building has two storeys plus an attic and features a three-window roughcast front facing St Mary Street. It has a slate roof with three hipped dormers that contain small-pane casement glazing. The eaves are adorned with a modillion cornice, and there is a band course between the floors, with plain pilasters at each end.
On the first floor, there are twelve-pane sash windows, while the ground floor features a central doorway flanked by a three-light canted bay window on either side. These bay windows have an enriched frieze and the sash windows do not have glazing bars. The central round-headed doorway has panelled reveals and is topped by a semi-circular fanlight with tracery, leading to a fielded panelled door.
Inside, the ground floor shop is now one open space, retaining the remains of a barrel-vaulted entrance hall. At the rear right, there is an elliptically-arched recess that is flanked by fluted Doric pilasters and has panelled reveals.
