Numbers 3 and 4 and Attached Railings

Numbers 3 and 4 in Blenheim Square, built between 1831 and 1839 and altered in the 20th century, are a pair of houses featuring attached railings. Constructed from red and brown brick in Flemish bond, with rubbed brick details and a slate roof, each house stands three storeys over a basement and has three windows across the front, with the entrance located to the right. There are steps leading up to the doors, which have fanlights in wooden surrounds, and the entrances are topped with keyed arches and imposts. The houses feature sash and casement windows, though some frames have been replaced, and they have stone sills with brick flat arches. A large multiflue stack is positioned at the centre of the ridge. At the rear, No. 3 retains its original stair window with glazing bars and a semicircular bay window with three 16-pane sashes on the ground floor, exemplifying the character of the entire row as seen on the 1847 Ordnance Survey map. The interior has not been inspected. The wrought-iron railings enclose the basement and flank steps and feature bud finials. This pair of houses is part of the second stage of the development of Finsbury Square, as indicated on Fowler's map from 1831, which included an oval garden at the front, although the southern terrace was never constructed.
