33, Upper Brook Street W1

No. 33 Upper Brook Street is a terraced town house built between 1756 and 1757, later transformed by Sir Robert Taylor in 1767-68 for John Boyd Danson, who had previously commissioned Danson Park. The house underwent alterations and was heightened in the early to mid 19th century. It features colour washed brick with stone dressings and a slate roof. Originally three storeys with a pediment, it now stands four storeys high with a basement and a dormered mansard roof. The façade is three windows wide, with a central doorway approached by five shallow steps. The ground floor windows are recessed in archivolt arched openings, showcasing a unique design with reduced scale engaged Doric columns and dosserets. The cornice projects and links the archivolts as an impost string, continuing beneath the fanlight above the six-panel door, which is framed in an architrave case.

The first floor windows rise from a pseudo parapet with blind balustrading below the sills and have architraves, with the central window featuring eared detailing and further emphasis from a cornice. The high-set second floor windows are also architraved, and there is a later attic storey with a sill band and a stucco-banded and coped parapet. Stone dwarf walls and dies flank the steps, which are accompanied by simple wrought iron railings.

Inside, despite some alterations, the house retains key features of Taylor's spacious design, including a plaster vaulted and saucer domed hall ceiling supported by Siena marble painted Doric columns. A typical apsed ended cantilevered stone staircase rises to the left, while the rear ground and first floor rooms are octagonal, and the front room on the first floor is cubic with a coved ceiling that still displays some of its original plasterwork.
