Numbers 11 and 12 and Attached Railings

Numbers 11 and 12 are a pair of houses built between 1822 and 1831, with some alterations made in the 20th century. They are constructed from red and brown brick in Flemish bond, featuring rubbed brick details and a slate roof. Each house has three storeys above a basement and is three windows wide, with the entrance located on the right side. There are steps leading up to the door, which has a fanlight above it. Number 11 has fine glazing bars to the right of the entrance, while both houses feature a plain stone surround with a keyed brick arch and imposts. The basement windows are topped with segmental arches, and the upper floor window frames have been replaced, with stone sills and flat brick arches. Large multi-flue stacks sit on the ridge between the two properties.

At the rear, Number 11 retains its original stair window with glazing bars and has a large brick semicircular bay window with a curved frame of glazing bars, flanked by 8-pane margin lights. The bay window of Number 12 has been rendered, and its stair window opening has had its lower frame replaced.

The houses are enclosed by railings that surround the basement area, although part of these railings has been replaced and they feature alternate bud and flower finials. This pair of houses is part of the first stage of the development of 'Finsbury Square', as shown on Fowler's map from 1831.
