Description

Numbers 20-23 Colebrooke Row are a group of terraced houses built in 1841. They were developed by William Watkins and likely designed by J.W. Griffith. The houses are constructed of yellow brick in a Flemish bond pattern, with some stucco sections. The roof is concealed behind a parapet. Each house is four storeys high with a basement, and generally features two windows, except for number 20, which has three, and a single-storey entrance bay set back to the side, with a projecting two-storey wing behind. Numbers 21 and 22 slightly project. The basement and ground floor are stuccoed, with the ground floor decorated with chamfered rustication. There is a segmental-arched entrance with pilaster jambs, a cornice, and fanlights, along with panelled doors of original design to numbers 20-22. The ground-floor windows are round-arched, while the first and second-floor windows feature flat arches with gauged brick heads. A continuous bracketed balcony with cast-iron railings runs along the first floor. A moulded stucco cornice and blocking course sits above the second floor, acting as a sill band for the third-floor round-arched windows. The sashes of the ground floor of number 20 and the second floor of number 23 are possibly original. The building has a parapet and cast-iron railings to the area.
