About
Description Occupying a commanding position moments from Belgrave Square, this extraordinary detached mansion unfolds across more than 11,000 sq ft of internal space, with eight bedrooms, a lift, garage parking and an exceptional suite of leisure and entertaining rooms.
In addition to the principal house, a separate three-bedroom mews house of approximately 1,500 sq ft is also included, offering further flexibility for guests, staff or independent accommodation.
Behind its imposing white stucco façade, the house opens into a grand entrance hall, where polished marble flooring and soaring proportions immediately set the tone.
The ground floor is arranged for formal entertaining on a rare scale, with a vast reception room, a separate dining room and a further reception space, all framed by remarkable ceiling heights, intricate plasterwork and tall sash windows that draw in natural light.
The first floor is devoted to a series of magnificent principal rooms, including an immense reception room of ballroom-like proportions and two substantial bedroom suites, each with generous dressing areas and ensuite bathrooms.
Throughout, the interiors strike a balance between period grandeur and contemporary comfort, with ornate detailing, marble fireplaces and a lift serving each level.
Across the upper floor are a further collection of beautifully proportioned bedrooms and bathrooms, offering impressive flexibility for family life, guests or staff accommodation.
Several rooms enjoy leafy views across the surrounding Belgravia streetscape, while the overall layout allows for both privacy and large-scale hosting.
The lower ground floor has been designed with everyday living and service in mind.
Here, there is an expansive commercial kitchen fitted with a triple Wolf range cooker and integrated Gaggenau appliances, as well as additional utility and storage spaces.
A comprehensive wellness section includes a gym, steam room, spa area and further ancillary accommodation, while the deep private garage provides secure off-street parking.
This is a house of rare scale and presence, a detached Belgravia residence that combines ambassadorial proportions with extensive private amenities, further enhanced by the inclusion of a separate mews house, in one of central London’s most distinguished garden square settings.
Belgrave Square sits at the heart of prime Belgravia, moments from the boutiques and restaurants of Elizabeth Street, Motcomb Street and Knightsbridge.
Hyde Park, Sloane Street and the amenities of Mayfair are all within easy reach, while nearby transport links include Hyde Park Corner, Victoria and Knightsbridge.
