At Twenty Grosvenor Square in Mayfair, General Dwight D. Eisenhower’s former London headquarters during World War II, a spectacular 5,750 sq.ft. three-bedroom triplex residence with interiors inspired by spymaster and James Bond author Ian Fleming (a frequent visitor to the HQ), featuring 24-hour concierge by Four Seasons, is available to let via Beauchamp Estates.
The residence provides luxurious accommodation over three floors, with opulent living and dining spaces on the upper level, three serene ensuite bedrooms on the middle floor (with two leading onto an expansive terrace), and a spectacular leisure and entertainment area on the lowest level, complete with internal garaging for two cars that can be viewed through floor-to-ceiling glazing.
Twenty Grosvenor Square is a grand Edwardian mansion building, built in 1933-35, which became a military HQ building in 1939 and from 1942 onwards served as the London headquarters of Allied Forces of which General Eisenhower was Commander-in-Chief. It was in this building that Eisenhower directed military operations during WWII including meetings with British Prime Minister Winston Churchill and the planning of the D-Day landings.
Another key person who visited the building during WWII was spymaster Ian Fleming, the author of the famous James Bond novels, who served in British Naval Intelligence and reported to General Eisenhower on various deception plans to mislead German forces.
Until 2009 the United States Navy used Twenty Grosvenor Square as its European HQ and then between 2014-17 the building underwent a £250 million luxury transformation by developer Finchatton and architects Squire & Partners into a new residential address.
Here, history and the best of British luxury design masterfully meet, with the building’s magnificent 1930s Italianate façade retained, along with the iconic giant marble eagle logo on the floor of the grand main entrance lobby, and impeccably stylish interiors within.
Twenty Grosvenor Square contains just 37 residences, with hotel-like amenities including a health spa with 25 metre (82ft) swimming pool, gym/fitness centre, treatment rooms, cinema, garden library, business suite, wine cellar and car park. Every resident receives the legendary service provided by Four Seasons including 24-hour concierge, security, housekeeping, in-residence catering and car valeting.
Beauchamp Estates highlight the residences at Twenty Grosvenor Square are amongst the most prestigious and sought after in Mayfair, and now a discerning resident can move into the fully furnished, turn-key triplex residence, one of the finest luxury lettings in London.
Completed recently, in 2021, the 5,750 sq.ft. triplex residence is known as 0.07, with glamorous and sophisticated James Bond inspired interiors devised as a homage to Bond author Ian Fleming and his WWII association with the building.
Entered at ground floor level, 0.07’s hallway leads into a large reception/dining space, which has a ceiling height of 3.7m (11.8ft) and is flooded with light by four huge sash windows with views over Grosvenor Square.
Grey engineered wood flooring lies underfoot, while a white marble fireplace provides classical elegance; bespoke furnishings and fittings including a Stark rug and a dining table that seats at least 10 people. A sleek designer fully fitted kitchen incorporates dark minimalist style cabinetry and an informal breakfast/dining area.
In the stairwell hangs a magnificent multilayered Lee Broom pendant, with a white marble staircase with contemporary black balustrade leading down to the middle level, which provides three beautifully decorated ensuite bedrooms, two of which open onto a private terrace via double sets of French doors.
The principal bedroom suite, with a ceiling height of 3.3m (10.8ft), is designed like James Bond’s bedroom, with tweed in the headboard, a nod to Bond’s Scottish heritage, complete with its own lounge area, and bespoke joinery in the walk in dressing room. The sumptuous ensuite features book matched monochrome marble, a huge bath tub and dual bespoke vanity units.
On the level below is the leisure and entertainment floor, providing the family/cinema room, with exceptionally high ceilings, of 3.28m (10.8ft), dressed with wool pinstripe wallpaper, vintage film posters and ultra-cool black-and-white photography.
A leather-trim sofa, handcrafted pool table and fully equipped marble-topped bar area (Bond’s Vesper Martini glasses and cocktail shaker provided, of course), add to the sense of escapism that Ian Fleming would have adored, while red velvet drapes across floor-to-ceiling glazing can be drawn back to reveal the double internal garage – perfect for displaying supercars.
Alongside the ultra-luxurious bespoke specification are seamlessly incorporated must-haves of contemporary London life, including a passenger lift connecting all three floors, air conditioning, underfloor heating, Crestron home automation and state-of-the-art security.
Directly adjacent to the two acres of landscaped gardens provided by Grosvenor Square Gardens Twenty Grosvenor Square is arguably in Mayfair’s best location, a short stroll away from the local Mount Street high street and the West End’s premier shopping boutiques on Bond Street, bars, private members’ clubs, art galleries, and restaurants such as Scott’s, George and Annabel’s. The Connaught Hotel, Claridge’s and the green acres of Hyde Park, Green Park and St. James’s Park are all within a short walking distance.
