Numbers 42-47 (Consecutive) and Attached Railings

Numbers 42-47, Canonbury Square, are a row of terraced houses built around 1810 as part of a development conceived by Henry Leroux. The houses are constructed of brown brick in a Flemish bond pattern, with roofs of Welsh slate. They are generally four storeys high above a basement, with the exception of number 47, which retains only the basement and ground floor. Each house originally had three windows.

The frontages feature round-arched entrances with gauged brick heads, reeded pilaster jambs, cornices, and fanlights with decorative glazing bars. The entrances have panelled doors of an original design. Number 47 has a panelled doorcase with scrolled detail and a decorative keystone. Ground-floor windows are round-arched with gauged brick heads, featuring sashes with radiating glazing bars. Upper-floor windows have flat arches and gauged brick heads. First-floor windows have a “piano nobile” feel, enhanced by balconies supported on brackets, with iron railings – replacements appear to be present on all houses except number 46. These windows are set within round-arched recessed panels with gauged brick heads. A parapet sits above the second floor, and dormers are incorporated into a mansard roof. Chimney stacks are situated on the party walls.

Early 19th century rainwater heads are located on numbers 44 and 46. Cast-iron area railings are present, topped with spear and urn finials.
