11, Foss Street

11 Foss Street is a shop with a house above, built around 1820 to 1830, with some alterations from the late 19th and 20th centuries. The building features mixed construction, including stone rubble party walls and plastered timber-framed fronts, with brick chimney stacks at the rear and right end, one of which is rendered and both topped with old chimney pots. The roof is slate.

The exterior has three storeys and a two-window range on the first floor. The plastered front is lightly marked to resemble ashlar stone. The ground floor has a late 19th-century timber shop front with two bays and no glazing bars. The left end corner features a large canted doorway with bottom-panelled glazed double doors and flanking pilasters. The shop front continues for another two bays along the return wall to Union Street. Each end of the shop front has panelled pilasters with large shaped brackets supporting the fascia.

At the right end of the front, there is a doorway leading to the house, which contains a late 20th-century panelled door beneath a plain overlight. The first floor features large sash windows, with a horned four-pane sash on the left and an original twelve-pane sash on the right. The second floor has 20th-century casements. A moulded timber eaves cornice is supported by pairs of modillions, with a pediment above. The roof is hipped, and the moulded cornice wraps around to the return on Union Street, where it lacks paired modillions. There are blind windows facing Union Street.

The interior has not been inspected but is likely to be of interest. Historically, Foss Street follows the line of a medieval dam that included a tidal mill. The mill pond was filled in and developed around 1820 to 1830, although houses had been constructed along the Foss since the 17th century.
