Live in a WWII-Era U.S. Embassy in London for £21.5 Million
The three-bedroom, duplex apartment in the notable Mayfair building spans 4,400 square feet

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.

Strong population growth, major infrastructure spending and comparatively affordable property are expected to cement Melbourne’s position as Australia’s most attractive long-term real estate market.

Melbourne is poised to become Australia’s largest city within the next decade, with strong population growth, infrastructure investment and relative affordability driving long-term property demand.
A new research report from Knight Frank argues the Victorian capital remains one of the country’s most compelling markets for investors, businesses and residents.
The report highlights the city’s rapidly expanding population, diverse economy and major infrastructure pipeline as key factors underpinning future property growth.
Knight Frank Managing Director Victoria, Dominic Long, said Melbourne’s fundamentals continue to position the city strongly for long-term investment.
“Melbourne continues to stand out as one of Australia’s most compelling real estate markets,” he said.
“It is Australia’s strongest long-term growth city with the fastest growing population, the most diversified economy, world-class liveability and the most affordable major market for office, industrial and residential property.”
Population growth driving demand
Melbourne’s population has grown at an average rate of 1.8 per cent per year since 2000, faster than any advanced global economy, according to the research.
In the year to June 2025 alone, the city added about 123,500 residents, the largest annual increase of any Australian capital.
Population growth is expected to remain one of the key drivers of demand across residential and commercial property markets, including housing, offices and logistics space.
The report forecasts Melbourne’s population will overtake Sydney’s by the 2030s, reinforcing its position as the country’s fastest-growing major city.
Office market offering value
Melbourne’s CBD office market is also attracting renewed attention from investors.
Prime office rents remain significantly lower than in competing cities, with CBD office space about 46 per cent cheaper than Sydney and around 13 per cent cheaper than Brisbane.
That relative affordability is expected to drive long-term demand from occupiers and investors seeking value in Australia’s largest office markets.
The city’s office sector is also showing signs of recovery, with effective rents rising in 2025 and demand increasing for high-quality buildings in premium locations.
Industrial market benefiting from scale
Melbourne’s industrial sector continues to expand, supported by strong population growth, e-commerce demand and the scale of the city’s logistics network.
The city already hosts the country’s largest industrial market, with about 34 million square metres of warehousing stock and significant land available for future development.
Industrial rents remain competitive compared with other capitals, while Melbourne’s port handles the largest container volumes in Australia, further supporting demand for logistics space.
Infrastructure pipeline supporting growth
More than $200 billion in transport infrastructure investment between 2014 and 2036 is also expected to reshape the city and support future property values.
Major projects include the Metro Tunnel, the West Gate Tunnel, the North-East Link and the Suburban Rail Loop, which together will improve connectivity across Melbourne and its growth corridors.
Knight Frank’s Head of Research & Consulting, Victoria, Dr Tony McGough, said these investments would play a key role in supporting the city’s economic expansion.
“Melbourne is Australia’s most economically diverse city and has delivered stable growth for more than two decades,” he said.
“With strong population growth, a highly educated workforce and unprecedented infrastructure investment, Melbourne is well placed to remain one of Australia’s most attractive long-term property markets.”
