Twenty Grosvenor Square combines the best of hotel services and private ownership, with the assurance that each home is being cared for to the highest standards of quality by Four Seasons. This landmark development has been masterfully designed by Finchatton, in collaboration with award winning architects, Squire & Partners.

0.07 is a triplex townhouse apartment, originally modelled on the suave wardrobe and exhilarating lifestyle of Ian Fleming's famous spy. It is found in immaculate condition, having had light use since being completed in 2021. The three-bedroom property spans approximately 5,750 sq ft and is spread over three floors, with a private in-residence lift to each level. Staying true to the heritage of Twenty Grosvenor Square, the developers' design team created a sophisticated space that has resulted in a contemporary family home.

3.7 meter plus ceilings and four Grosvenor Square facing windows combine to create a stunning reception room with fully kitted kitchen adjoining for entertainment. Accommodation further comprises three en suite bedrooms, two of which lead out onto the terrace. The entertainment room, with its floor-to-ceiling window framed by red velvet curtains, overlooks the only internal, private double garage in the building.
Additional information
We have been informed that the building has been constructed using some combustible materials. However, we have received documents confirming that the building has been assessed by a competent person, who has concluded that the fire risk is sufficiently low, and that no remedial works are required to the external wall of the building. If necessary, further information can be provided upon request.


Twenty Grosvenor Square benefits from a wonderful location in the very heart of Mayfair; London's oldest and most renowned district. Its garden walkways, colourful planting and statues represent its rich heritage, and are aptly surrounded by some of the city's most iconic, classical architecture.

The property is superbly located for the finest boutiques, bars, private members' clubs, art galleries and restaurants that Mayfair and the West End have to offer, including Scott's, George and Annabel's. It is within close proximity of The Connaught Hotel and Berkeley Square, and the extensive, open spaces of Hyde Park, Green Park, St. James's Park and Mount Street Gardens are all within walking distance.

Excellent local transport links include Bond Street Underground (Central, Jubilee and Elizabeth Lines) and Green Park Underground (Jubilee, Piccadilly and Victoria Lines).

    Broadband speed is measured in megabits per second, with the number returned showing how fast the connection is. Each reading is based on the highest predicted speed of any major broadband network for services that deliver the download speeds. The following are the different readings that we may display:

    Basic: Up to 30 Mbit/s
    Super-fast: Between 30 Mbit/s and 300 Mbit/s
    Ultra-fast: Over 300 Mbit/s

    The data is updated three times a year. The checker results are predictions and should not be regarded as guaranteed. For more information, see: https://checker.ofcom.org.uk/en-gb/about-checker#Answer_0_2

    Mobile phone signal availability and predicted strength: obtained from Ofcom on August 31, 2022

    Mobile signal predictions are provided by the four UK mobile network operators: EE, O2, Three and Vodafone. Predictions can vary significantly from the coverage you may actually experience as a result of local factors (especially terrain). Ofcom has tested the actual coverage provided in various locations around the UK to help ensure that these predictions are reasonable. The values shown against a property can be broken down as follows:

    Clear: No bars, no signal predicted
    Red: One bar, reliable signal unlikely
    Amber: Two bars, may experience problems with connectivity
    Green: Three bars, likely to have good coverage and receive a data rate to support basic web services
    Enhanced: Full bars, likely to have good coverage indoors and to receive an enhanced data rate to support multimedia services
