Live in a WWII-Era U.S. Embassy in London for £21.5 Million

In the heart of London, a duplex apartment within the city’s former U.S. Embassy, which has been recently transformed into super-prime residences, has hit the market for £21.5 million (US$26.9 million).

The unit, which has been given the presidential moniker of the “Oval Residence,” is within No. 1 Grosvenor Square, and is the last sponsor unit available from developer Lodha UK. The building, on Mayfair’s uber-posh Grosvenor Square, served as the U.S. Embassy from 1938 until 1960, and then as the Canadian High Commission from 1962 until 2013. After being restored brick by brick, quite literally , it reopened as residences in 2022.

Some of the prominent figures of the 20th century have passed through its doors, including John F. Kennedy, who called it home when his father was appointed U.S. Ambassador to the U.K. in the 1930s, Winston Churchill and Eleanor Roosevelt, who was loaned an apartment when she visited London during World War II.

The three-bedroom home spans 4,400 square feet and was designed by Blandine de Navacelle, creative director of Studio Lodha, the developer’s interior design practice.

“No.1 Grosvenor Square is one of the capital’s most iconic addresses, and the design of the Oval Residence needed to reflect this,” de Navacelle said in a news release. “With large, open-plan living spaces and floor to ceiling windows, the residence offered the perfect backdrop for statement artwork and eclectic, sculptural furniture.”

The home also boasts a sleek kitchen, a home theatre, a dining area, wood-panelled walls, fireplaces and a 576-square-foot terrace.

“I regularly visit French galleries and furniture ateliers and am drawn to their art-centric approach to design and interiors,” de Navacelle said. “I wanted to bring a touch of this Parisian eclecticism to No.1 Grosvenor Square, creating a sophisticated and elegant private residence that blends both the classic and the contemporary.”

The turn-key flat is being sold with all of its furnishings.

Future occupants will also have access to the building’s amenities, including an in-house concierge team, a private health club and spa, a pool and a cinema.

Grosvenor Square has been one of London’s most-famed addresses for centuries. Currently in the middle of a dramatic remaking, No.1 Grosvenor Square is just one the enclave’s storied buildings to be undergoing, or to have undergone, a complete transformation.

The former U.S. Naval Building at No. 20, has been transformed into the first solely residential project from the Four Seasons, and the iconic Eero Saarinen-designed U.S. Embassy that spans the entire western side of the square, is set to become the Chancery Rosewood hotel by 2025.

London has no shortage of diplomatic buildings that have been transformed into luxury homes. In February, and for the first time in more than a century, the former Italian Embassy, now a lavish mansion, hit the market for £21.5 million . The former Cypriot Embassy, meanwhile, sold in March for £25 million to a buyer seeking a grand family home in the city.

A growing number of major UAE property groups are turning their attention to Australia, with BNW Developments the latest to establish a local presence.

BNW has officially opened a Sydney office after hosting more than 300 investors, property professionals, wealth advisers and industry figures at its launch event.

The new office will give Australian buyers local access to BNW’s portfolio of residential and hospitality-led developments in Dubai and Ras Al Khaimah. Its projects include branded residences and waterfront developments combining private homes with hospitality, dining, leisure and tourism facilities.

BNW has an AED32 billion development pipeline, equivalent to approximately $12 billion, spanning projects in Dubai and Ras Al Khaimah. Its portfolio includes developments associated with Tonino Lamborghini, Radisson Blu and Wyndham Hotels & Resorts.

Among them is Tonino Lamborghini Residences in Ras Al Khaimah. BNW is also active on Al Marjan Island, the waterfront destination where the Wynn Al Marjan Island integrated resort is under development.

The developer recently announced Dolce Residences in partnership with Wyndham Hotels & Resorts. Billed as the world’s first residences carrying the Dolce name, the boutique Al Marjan Island project is planned to include 93 premium residences and five retail tenancies.

BNW Developments chairman and founder Dr Ankur Aggarwal said attendance at the Sydney launch indicated that Australians were increasingly interested in the UAE as both a property and lifestyle destination.

“The response to the opening of our Sydney office has been extremely encouraging,” he said.

“Dubai and Ras Al Khaimah offer a very different lifestyle proposition to Australia, from waterfront living and luxury hospitality to world-class dining, entertainment and tourism.”

Dr Aggarwal said the Sydney office would allow buyers to examine BNW’s portfolio locally and work with a team familiar with the Australian market.

The move comes as Australia attracts increasing interest from UAE-based developers seeking opportunities beyond their home market.

Arada entered Australia in 2024, initially announcing a $2.5 billion Sydney pipeline expected to deliver more than 2,500 homes. Its Australian plans have since expanded to eight projects comprising more than 5,000 homes, including a recently announced twin-tower development at Broadbeach on the Gold Coast.

The company has also acquired the NSW arm of tier-one contractor Roberts Co, giving it greater control over construction and delivery as it builds its Australian business. Globally, Arada says its portfolio of existing and future developments across the UAE, Australia and the United Kingdom is valued at AED130 billion.

Dubai-headquartered Sobha Realty is also laying the foundations for a substantial Australian presence. The developer has established local operations and acquired sites in Sydney and Queensland, describing its entry as a long-term commitment to the market.

Sobha has expressed interest in opportunities across Brisbane, the Gold Coast and Sunshine Coast, while its Australian website says new projects will be announced shortly. The expansion follows AED30 billion in global sales during 2025 and forms part of a wider international growth strategy encompassing Australia and the United States.

BNW’s Sydney opening reflects both the international ambitions of UAE developers and growing Australian awareness of the Emirates’ property market.

While the UAE and Australian markets differ considerably, the arrival of BNW, Arada and Sobha points to a broader exchange of capital, expertise and buyers between the two countries. For Australians considering offshore property, the opening of local offices may also make it easier to assess projects, understand the purchasing process and undertake appropriate due diligence before committing.
