This landmark property in the historic West Wing of One Grosvenor Square, this 5,300 sq ft home pairs grand lateral space with an atmosphere of total privacy. Recently refurbished to an exceptional standard, every room has been designed with a level of detail more often associated with a private members’ club than a home. The result is one of the square’s most incredible interiors, combining classical proportions with a modern palette of marble, bronze and bespoke cabinetry throughout.
