1-18 Wilton Square and attached railings

These are a row of terraced houses, numbers 1 to 18, built in 1851-52 as part of the development of Wilton Square in Islington. They were designed by Edward Rowland and Thomas Evans. The houses are constructed of yellow brick laid in a Flemish bond pattern, with stucco detailing, and have a roof hidden behind a parapet. They occupy part of three sides of the square's irregular layout.

Each house has two storeys over a basement, with two windows on each floor. The basement is stuccoed and features a moulded storey band. Steps lead to flat-arched entrances, each with pilasters, a pediment supported by consoles, and an overlight. The original panelled door remains at number 13. All windows are segmental-arched and have moulded stucco architraves; balconies are present below the ground-floor windows of numbers 8 to 14 and 18. Window guards are found at numbers 12 to 14 and 18. A sill band runs along the first floor. The windows are sash windows with six panes per sash, as seen at number 18. The houses have a corniced detail and a blocking course. Chimneys are located on the party walls between the houses, although some appear to be missing. A carriage entrance is situated at number 11. Attached cast-iron railings provide the area boundaries.
