NUMBERS 13 TO 19, 19A, 20 TO 20B, 21 AND ATTACHED RAILINGS

Numbers 13 to 19, 19A, 20 to 20B, 21 and attached railings comprise a group of nine terraced houses built between 1819 and 1831, by John Wilson, who was builder for Lord Compton and the Spa Fields Estate. The houses are constructed of yellow brick laid in Flemish bond, with banded stucco to the ground floor and stucco dressings. The roofs are hidden behind a parapet, and brick party-wall stacks are visible. They are arranged with a side-hall entrance and staircase.

The houses are four storeys high with a basement. Most have two windows, except for the original number 20, which is now part of a larger flat and retains a three-window (all blind) range to its return wall. The group is symmetrical, featuring projecting end houses (numbers 13-15 and 19-21), with numbers 16-18 forming a plain recessed central section. Steps lead to the entrance of the left-end house, which has a single-storey entrance extension. A round-arched doorway is set within a narrow stucco recess, flanked by fluted quarter columns supporting a corniced head. Each doorway features a fanlight (patterned on numbers 13 and 17) and an original panelled door, except for number 13. Ground-floor windows are round-arched sashes with mostly 6/6 curved and radial glazing bars. Gauged brick arches feature above the upper-floor windows. The first floor has a stucco sill band, beneath full-length 6/6 sash windows with coupled cast-iron balconies supported by iron brackets. Windows on the second and third floors are 6/6 and 3/3 sashes respectively. A stucco storey and sill band, and a projecting cornice, are found on the third floor. The houses have a plain brick parapet with a brick string course and stone coping. Attached cast-iron railings with urn finials are also part of the group.

Wilmington Square was created from the Earls of Northampton’s Spa Fields Estate, which in 1817 was assigned by the 9th Earl to his heir, Lord Compton. The square was one of London's first post-Waterloo developments, though progress was piecemeal. The south terrace was the first and grandest section, while numbers 13 and 14 were constructed concurrently. However, numbers 15 to 21 were only completed in 1831, and the square’s depth was reduced due to financial constraints, resulting in its position on the fringes of larger estates.
