Nestled in the heart of the city, on a property the scale of multiple football pitches, sits a mansion called the ambassador's home—the official residence of the American ambassador to the United Kingdom.
While it may be a grand home, it has over time gained a reputation for throwing spectacular parties, especially on the Fourth of July—the United States' national holiday. The most recent celebration featured Nile Rodgers & Chic entertaining on the grounds for a large crowd of guests.
A Legacy of Entertainment
Fashion's elite, athletes, and military figures have all been hosted at the property. Even the early 19th century, when the initial site was constructed, its primary use was for social gatherings, as noted on the property's historical records.
Former President Donald Trump is spending the initial evening of his state visit at the spacious residence. The Trumps also stayed there in recent years, as did the Bidens in the past.
"This is more than the residence of the diplomat, it serves as a centre of diplomatic entertaining," says a retired staff member knowledgeable about the property.
Exclusive and Secure
What the residence isn't is a tourist attraction. Situated within a royal park, it is private and demands planning to enter. Visits of the grounds were once arranged by community organizations, but currently this year, permission has been restricted.
Standing on the road nearby, the mansion cannot be seen. It is surrounded in trees and provides remarkable seclusion for a downtown location.
"It's really challenging to gain entry. It felt like a personal achievement that I was able to enter," recalls one visitor who calls the property "magnificent" and shows admiration for the grounds.
Tours only allow access to the main level, which serves as a "very posh" area for receptions, and the outdoor areas. The first floor is reserved for the personal apartments of the ambassador.
Being both a residence and a site for most American functions, timings are tight. "It wasn't a matter of we would like to visit on a chosen day. Instead, it was simply, you will be allowed to come on the premises on a set date," explains the source.
The estate boasts the one of the biggest private garden in central London, as stated by reports. It contains a grassy area, stone paths, sculptures—and additionally has space for helicopters to land.
Past Significance
Socialite and beneficiary to the Woolworths fortune Barbara Hutton transferred Winfield to the US government for only dollar in the mid-20th century in an offer viewed as "most generous" by the then-president Harry S Truman.
Hutton had purchased the mansion 10 years prior, after it was significantly destroyed in a blaze. Authorities allowed her to tear it down and reconstruct it in the iconic brickwork architectural design that still stands now.
She named it after her relative, Frank Winfield Woolworth, the creator of the retail store network.
As the Second World War approaching and her second marriage facing difficulties, Hutton returned to the US with her son in the late 1930s. It would later be discovered that this is when she encountered her future spouse—actor Cary Grant—who is said to have resided at the mansion with her.
Historical and Recent Use
During the war, Winfield was commandeered by the military balloon barrage unit with personnel allegedly playing sports in the gardens.
She returned to London to see what was left of the property at the conclusion of the war—and after the enemy bombs. She contacted her lawyer and asked that it be donated to the US government for restoration—and it has been served as the official residence of diplomats from that time onward.
History is embedded in the walls of the mansion. The original structure was called a historical title, and according to historical records, was employed for visually impaired soldiers of World War One. A non-profit of the same name still exists currently.
Commenting about US presidents, a former employee states: "At some point they all visit, at least one time." He explains encountering the former president and his spouse Melania during their previous state visit in 2019, which was "a little bit unusual". They ate at the property with the queen and the monarch before he rose to the royal position.
A famous image of the Soviet leader—the final USSR head of state—and American leader George W Bush may be one of the best-known moments from the property. The two held a joint news conference there at the international meeting in 1991.
Leaders have historically used it for important events, including global conferences, elaborate state dinners, and uniting military figures.
Events and Security
Winfield House has staged many diverse functions, according to accounts.
There have been shows by Take That, the Foo Fighters, and other artists, occasionally in the garden and at other times within the mansion.
It's also been home to sporting events with the Duke of Sussex attending an Invictus Games reception there. A former first lady got stuck in with a competition, even doing the team event alongside some famous spectators.
Fashion elite has also graced the halls of the property. A former Vogue editor organized a design event opening party with the ambassador at the time. A Spice Girl was spotted as well.
Some of the events would attract "several thousand" of guests, with the 4 July parties usually gathering a large crowd.
An Secluded Retreat
It's a something of an escape.
"You would never know you're in the middle of London," says one guest.
But what's the most disappointing aspect of the mansion? A person says its driveway is "rather modest" in contrast with the rest of the estate.
"It's big enough for large vehicles but you couldn't get a parade of guards marching etc.. It's not like the Mall."
