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.

Jenna and Michael Morton have created some of the best-known nightclubs and restaurants in Las Vegas.

But when building a home in the area for their family, they veered away from the glitzy excess of the Strip in favour of a calming, desert retreat.

That’s not to say entertainment was an afterthought: The roughly 2-acre property in the Summerlin neighbourhood has a 60-foot outdoor slide and a DJ booth.

“We are in Las Vegas,” Jenna said. “It’s part of what we do in this town. We do fun.”

Now, after about 20 years of fun, the Mortons’ three children are out of the house, and they are listing the home for $19.5 million.

Michael is a son of Chicago restaurateur Arnie Morton, who founded Morton’s The Steakhouse, which has more than 50 locations nationwide.

His brother Peter Morton co-founded the Hard Rock Cafe, and Michael and Jenna operate restaurants including Crush at the MGM Grand and La Cave Wine and Food Hideaway at Wynn Resorts .

The couple paid $1.25 million for the vacant Summerlin site in 2003. At the time, they were living in Chicago but planning to move to Las Vegas to be closer to their work.

Located in the Ridges, a gated community about 15 minutes from the Strip, the property is at the end of a cul-de-sac abutting the Red Rock Canyon National Conservation Area.

“The first time we were there, there were wild burros behind us,” Michael said.

The single-story house spans about 9,400 square feet and curves toward the canyon for privacy and mountain views.

“The curve is an embrace of the mountains,” said Jenna during a video call as she walked outside, the vista framing her face.

In contrast to the over-the-top vibe of Las Vegas hotels and casinos, the couple’s aesthetic at home is what Jenna described as “Japan meets desert,” with clean lines and neutral colours.

The house has seven bedrooms; the primary bath has a soaking tub made out of a boulder.

A wine room has colour-changing Lucite pegs that hold hundreds of bottles. A separate, roughly 530-square-foot guesthouse has a roof deck.

The property is mostly flat, with the exception of a sloped section where the Mortons built the tiled slide, which drops into the pool.

“I looked at it and said, ‘There will be a slide on that hill,’” Michael recalled. It isn’t just children who have enjoyed it—he and Jenna and many of their friends have taken a turn. “A lot of adults hit that slide,” he said.

The Mortons said they entertained frequently, from fundraisers to a birthday party where their son filled an outdoor trampoline with bubbles.

For Jenna’s 40th birthday, the couple hosted a 1960s-themed party that began with a 200-person sit-down dinner, followed by toasts and karaoke.

Michael enlisted the rock band Cheap Trick to make a surprise appearance during karaoke.

As Jenna took the microphone and started belting out their song “I Want You to Want Me,” the band began playing behind her. “We took the rods out of the reactor that night,” he said. undefined

Although selling is bittersweet, the Mortons said they want something smaller now that their children are grown.

The couple—he is 61, she is 59—have a second home in Manhattan Beach, Calif., and they plan to build a smaller house in Las Vegas.

The luxury market in Las Vegas has exploded over the past few years, said listing agent Kristen Routh-Silberman of Douglas Elliman.

There were 76 sales in the Las Vegas area above $10 million in 2025, up from 59 a year prior, she said. The record is held by a home at the Summit Club that traded for $35 million in 2024.

A recent building boom means inventory is finally catching up to demand, according to Routh-Silberman.

The spring market has started early this year, and there seems to be more activity thanks to demand from California and Washington transplants seeking tax advantages, she said.
