It contains glazing bar sash windows, with the ones on the first floor being wider and slightly segmental. There are two shop fronts on the ground floor; the shop front on the left was altered in the late 19th century and has a pair of half-glazed doors in its centre. The detailing includes grey headers and red brick dressings.
