Numbers 1 to 12, 12a to 12c (Consecutive) and Attached Railings

Numbers 1 to 12, and 12A to 12C form a terrace of twelve houses with attached railings, built between 1819 and 1831 on the Spa Fields Estate for Lord Compton. Numbers 8 to 11 were reconstructed after the Second World War, and the pediment to number 12 was rebuilt around 1989. The houses are constructed of yellow brick in Flemish bond, with banded and rusticated stucco detailing to some properties, and have brick party-wall stacks. The design follows a side-hall entrance plan with a staircase.

The houses are four storeys high with a basement, and generally feature two windows each, except numbers 6 and 7 which have three, and the return walls to Yardley Street and Tysoe Street each have a single-window range. The front is symmetrical, with projecting, pedimented end houses and a pedimented centrepiece to numbers 6 and 7, which projects forward. Steps lead to entrances; number 1 has a single-storey extension, while numbers 12A to 12C have a full-height canted extension. Round-arched doorways are set within a narrow stucco recess with fluted columns, a corniced head, a fanlight (patterned in numbers 1 to 7), and panelled doors. The ground floor windows are round-arched sashes with 6/6 curved and radial glazing bars. Numbers 8 to 11 have been extensively altered since the war, with a single front door serving as "8-11" (originally number 9) and a nine-window range instead of the original ten. Gauged brick arches are above most windows, except for the round-arched first-floor sashes at the end and centre pieces. The first floor features stucco sill bands below full-length 6/6 sashes, often with coupled cast-iron balconies supported by iron brackets. Stucco bands define the second (6/6 sashes) and third (3/3 sashes) floors, the latter also featuring a projecting stucco cornice and sill band. The building has an altered stucco cornice and blocking course. The end and centrepiece houses feature stucco pediments, with the one at number 12 having been rebuilt, displaying crossed laurel branches in low relief. Attached cast-iron railings are topped with urn finials. Wilmington Square was developed as part of the Earls of Northampton’s Spa Fields Estate, becoming one of London’s first post-Waterloo developments; its reduced depth resulted in its position on the fringes of larger estates.
