From presidential to residential

A former US embassy, No.1 Grosvenor Square embodies the history and culture of Mayfair


For close to three centuries, Grosvenor Square in Mayfair has been one of London’s most prestigious locations. And sitting at the best position, is No 1 Grosvenor Square. As a former US Embassy and Canadian High Commission, previous residents have included John Adams, before he became the second President of the United States, while a young JFK lived here when his father Joseph P Kennedy was appointed US Ambassador to the UK in the 1930s.

“Although the square has been one of London’s most upmarket residential addresses since the 18th century, there hadn’t been any significant development since the 1930s,” says Ed Lewis Head of Residential Development. “That has changed significantly in the past few years, and the restoration of No 1 into 44 luxurious residences represents the renaissance of Mayfair into a star residential area.”

Despite its illustrious past, this neo-Georgian building had been in need of extensive restoration to revive its sense of style. To achieve that, the building was dismantled, each brick being painstakingly removed and catalogued before transporting for storage.

“It was a time-consuming process but reconstructing the façade this way rather than building behind it meant that interiors could be redesigned, window spaces enlarged, and ceiling heights raised to an exceptional 4.2m for properties on the ground floor, and more than 3m on the upper levels.” says Lewis.

The task of defining these grand interior proportions fell to the design house Yabu Pushelberg. The designers source the most interesting materials in the world for their compelling, contemporary interiors, including – in the case of No.1 Grosvenor Square – rich Italian marble and American black walnut.

Spanning an entire floor of more than 10,000 square feet, first-class amenities include a private screening room, residents lounge and an executive business suite. Residents also have exclusive access to health and wellbeing facilities that include a gym with personal training studios, a 25m swimming pool, vitality pools, steam rooms, sauna and private treatment rooms.

No 1 Grosvenor Square is also equipped with state-of-the-art security features and trained personnel on-site around the clock. To safeguard privacy, a discreet and covered vehicle drop-off point provides private off-street access managed by the 24-hour concierge and secure valet parking.

One part of the building’s compelling historical narrative has been preserved. The oval room – a replica of the Oval Office in the White House – now forms part of the impressive entrance lobby.

“Mayfair has a rich history, a superb location in the heart of London, and is close to sought-after hotels and shops such as Claridge’s, The Connaught and Bond Street,” says Lewis. “With No 1 Grosvenor Square, it now has residential at the top end of the market.”
