Numbers 18-21, 21a, 23-28 (Consecutive) and Attached Railings

Numbers 18-21, 21A, 23-28 form a terrace of houses built between 1833 and 1835 in Barnsbury Park, Islington. The houses are constructed of yellow brick in Flemish bond, with painted and stuccoed sections, and stucco dressings. The roofs are covered with asbestos slates where visible. The general design is of two storeys over a basement, with dormers in the attic. Most houses have three windows wide, though numbers 21, 21A, and 28 have two.

The houses share a common design, with a central entrance. The outer bays on numbers 18-20 and 26-7 project forward, while on numbers 23-5, only one outer bay does. The entrances are framed by stuccoed bays with panelled pilasters, cornices, fanlights, and original panelled doors. A ground-floor window is tripartite, flat-arched, and set under an elliptical arch of gauged brick with a plastered tympanum decorated with a wreath. Other ground-floor windows are flat-arched with gauged brick heads. A stucco sill band runs along the first-floor windows, which repeat the arrangement of the ground floor, with a flat-arched window in the middle. Original sash windows are found throughout. A stucco cornice and blocking course top the facades. Stacks are located on the party walls.

Notable features vary from house to house: numbers 18 and 19 have Doric porches, distyle in antis, and decorative fanlight glazing. Number 19 lacks original sash windows and has an ornate cast-iron window guard to the ground-floor right-hand window. Number 20 has elliptical-arched windows to the outer bays, original sash windows to the left-hand first-floor window only, and a flat-arched dormer. Number 21 has lost its left-hand bay to number 21A, which features a carriage or workshop entrance at ground floor, replacement windows above, and an added storey within a mansard roof. Number 23 has a recessed, partially stuccoed section, lacks original sash windows to the right-hand first-floor window, and has an added storey in a mansard roof. Number 25 has a recessed, partially stuccoed section, lacks original sash windows to the right-hand ground-floor window, and has a dormer in the attic. Number 26 has painted brickwork on the ground floor and original sash windows only to the left-hand first-floor windows. Number 27 has an enclosed stucco porch with Doric antae, a mutule cornice, round-arched side windows, double doors of original design, lacks original sash windows, and has segmental-arched windows in the left-hand bay. Cast-iron railings are found to the area of numbers 18-21 and 25-26, with number 19 also featuring ornate standards with anthemion ornament.
