Numbers 11, 12 and 13 and Attached Railings

Numbers 11, 12, and 13, along with the attached railings, are early 19th-century houses that were later converted into woollen warehouses and are now used as offices. They feature a basement with wrought-iron railings and are constructed of red brick in Flemish bond with stone details and a slate roof. The buildings stand three storeys tall over a basement, comprising two three-bay houses and a narrow two-bay house that connects to a three-bay return at No. 8 Britannia Street.

No. 11 has steps leading up to a panelled door with an overlight, framed by a stone architrave supported by deep scrolled brackets, an entablature, and a cornice. The windows are sash style with glazing bars, featuring nine panes on the top floor, stone sills, and segmental brick arches, with a sill band on the first floor. No. 12 mirrors No. 11 and has a large 14-flue ridge stack with clay pots on the ridge between the two houses. No. 13 has a slightly set-back facade with a plain segmental-arched doorway and overlight on the left and a sash window on the right, along with an inserted four-pane sash on the first floor to the left. The right return has a central doorway similar to Nos. 11 and 12, restored sash windows, and a four-pane window on the first floor left of each bay, topped with a hipped roof and a rebuilt stack. The railings are plain with pointed finials.

The interior was not inspected. Historical evidence suggests that Nos. 11 and 12 were likely built around 1831-34, with No. 13 and No. 8 Britannia Street added by 1850 when Britannia Street was developed. By 1870, the directory indicated that these houses were occupied by a woad grower, a gentleman, and an oyster merchant; by 1886, they had all become woollen warehouses.
