Description

A row of six houses, numbered 33 to 49, located on Blenheim Terrace in London, was built around 1830 to 1840. The houses are constructed primarily of brick with stucco dressings, and have a hidden roof. They are three storeys high, with a basement level, and each house has a two-window frontage. Steps lead to a square-headed entrance on the left side, featuring an architrave and cornice. The entrances are fitted with panelled doors. The ground-floor windows have architraves and cornices, with gauged arches above. They are sash windows with glazing bars. Cast iron window guards, in a pattern of crossed arrows, are present on the first floor of numbers 47 and 49. A simplified cornice sits above the second floor. Some cast iron area railings are also present.
