17, Grosvenor Place Sw1

No. 17 Grosvenor Place is a terraced town mansion built around 1868 by Thomas Cundy III. Constructed from Portland stone and some pink granite, it features a slate roof and is designed in an eclectic "French Renaissance" style, which is slightly different from the adjacent Nos. 6 to 16. The building has four storeys and a basement, with two storeys of dormers beneath a tall French pavilion-dome roof and mansard. It is four windows wide and has a long return, with an entrance and two canted bays that rise through three storeys.

The entrance is marked by an arched stone porch with enriched panelled pilasters and a balustraded parapet. The first floor features large recessed plate glass sashes with enriched archivolt arches. There are sill and band courses, a bracketed main cornice, and a parapet. A bracketed stone balcony on the first floor is adorned with an ornate cast iron balustrade, and there is iron cresting on the pavilion roof. The area is enclosed by a stone balustrade. This building is part of the Grosvenor Estate redevelopment of Grosvenor Gardens and Grosvenor Place that took place in the late 1860s.
