30, Curzon Street W1

No. 30 Curzon Street is a large terraced town house built in 1771, with its interior decorated by Robert Adam between 1771 and 1772. The building features a stucco exterior with a rusticated ground floor and a slate roof. It stands four storeys high, including a basement and a dormered mansard, and has six windows across its front. The entrance is slightly off centre to the left, featuring a porch supported by Doric columns and a mutule open pediment. The entrance includes a six-panel door with a radial glazed semicircular fanlight above it. The windows are revealed sash types without glazing bars, and those on the first floor are adorned with alternating pediments. There is a sill course on the second floor, a bracketed main course above it, and a crowning cornice with a blocking course. Wrought iron railings enclose the area in front of the house. The interior retains Robert Adam's decoration in the entrance hall, principal ground floor rooms, and a very fine ballroom on the first floor. The staircase is notable for its stone treads, wrought-iron panelled flat baluster rails, and a mahogany handrail, along with original door furniture.
