16, Upper Grosvenor Street W1

No. 16 Upper Grosvenor Street is a terraced town house built around 1730 by Joshua Fletcher, with early and late 19th-century alterations. The building has a stucco facade, with the upper floors finished in 1881, and a slate roof. It stands four storeys tall, with a basement and a dormered mansard, and features three windows across its front. The ground floor is channelled and includes an early 19th-century segmental arched doorway on the left, which has a six-panel door and a patterned fanlight above. The upper floors have square-headed recessed sash windows with shallow architraves, and the first floor has French casements. There are sill bands on the second and third floors, topped by a crowning cornice and blocking course. An early 19th-century cast iron balcony with a geometric pattern is located on the first floor. The area is enclosed by wrought iron railings with urn finials. Inside, the house retains a stone dog leg main staircase featuring bracket cut soffits and a wrought iron balustrade for the first four flights, which have an open work baluster pattern. The open well back stairs have turned balusters and a deeply moulded handrail. The front ground floor room still has part of its original panelling.
