11 and 12 Gun Street

11 and 12 Gun Street is an early 19th-century house or pair of houses that now function as apartments, featuring a modern shopfront. The building is made of red brick and has a slate roof.

It is three storeys tall, plus a basement, and spans three bays with brick walls laid in Flemish bond. The ground floor has been partially rebuilt, showcasing a modern plate glass shopfront and a 20th-century inset doorway under a segmental arch. Above the left and central bays, there are shallow brick piers and brackets that support three courses of corbelled brickwork.

The first and second floors each contain three recessed window openings with flat-arch heads made from gauged brickwork and stucco cills. The windows have uPVC casements that mimic the appearance of six over six sash windows. Above the second-floor windows, there is a stucco cornice and a parapet that appears to be coped in lead.

The side and rear walls have been rebuilt in red brick laid in header bond. The rear elevation features a single window on both the first and second floors. The roof is M-shaped, with two hipped slopes that create a central valley running perpendicular to Gun Street.
