They say good things come to those that wait – however, the mystery seller of a £195 million Regent’s Park mansion didn’t need to wait very long after netting a £56 million profit (US $75 million) in under two years.
The 208-year-old London address is as heavyweight as they come; a triumph of a house, the Regency-era megamansion sits on four acres of Regent’s Park’s Inner Circle with views over an ornamental boating lake.

It counts as one of London’s best – and the second most expensive – single-dwelling addresses after Nick Candy’s landmark £265 million sale of Providence House earlier this year.
Known as The Holme, a Saxon word referring to a small island or elevated piece of land in water or a river, the cream stucco-front was designed by 18-year-old architect Decimus Burton in 1818 when Regent’s Park was the high-water mark of Regency-era London; he unwittingly dreamed up what would be one of the costliest family homes on the planet.
A very complicated, very London history
The stucco-fronted, Grade II-listed megamansion, nicknamed “London’s White House”, has seen various iterations and numerous ownerships over its 200-year history.
First used as a primary residence for the wealthy Burton family, it became the flagship home of various members of London’s high society, and later served institutional purposes, including as a campus for Bedford College, before reverting to private residential use.
Somewhat of a real estate hot potato, The Holme has most recently been passed through the hands of a roster of the world’s billionaires with colourful connections with equally feisty asking prices reflecting the mercurial temperament of the London trophy real estate market.
In 1991, The Holme was purchased by Saudi Prince Khaled bin Sultan al-Saud along with other members of the royal family for £34 million via Guernsey-registered company Quendon Ltd.
The company listed the prince’s five children as its beneficial owners, with further complications down the road.
Twenty years later, the property fell into receivership in 2023 after a £150 million loan secured against the house expired, leading to the seizure of the property and public listing for a reported price of £250 million – the highest in its history – making it the most expensive UK transaction at the time should the property have reached full asking price.
It didn’t. First reported in the Financial Times, the residence was acquired for significantly less – £139 million – by a UK subsidiary of Luxembourg-based high-net-worth investment firm Zedra Trust Company, acting on behalf of an unknown client.
A trust was used to obscure the identity of the incoming buyer, who reportedly intended to use it as corporate offices with private residences attached.
Having owned it for under two years, we can only presume little or no renovation work was carried out – making the stately home in the centre of London one of the most expensive ‘do-er uppers’ in the world.
With both seller identity and reason for flipping shrouded in mystery, the plot thickens as those at the top of London’s residential food chain play a game of super-prime real estate Cluedo – the tightly-held identity still tightly under wraps.
A legacy asset in a league of its own
Little is also known of the transaction itself. Announced in early June, the sale of the Regent’s Park palatial home was made off-market. Rumours, unsubstantiated, point to an American buyer.
Despite a stymied prime and ultra-prime market putting the brakes on London trophy acquisitions and higher inflation, taxes, and geopolitics blowing frosty crosswinds, US investors, particularly those leaving Trumpian America and galvanised by a stronger exchange rate, have been snapping up London’s well-priced, ultra-high-end homes – particularly those with lock-up-and-leave credentials.
The Holme, however, isn’t that. It’s a one-of-one marquee asset with an unrivalled pedigree, footprint and location.
As such, investors should view the £195 million price point for The Holme as a unique valuation anchor – not a market indicator signalling that the world’s most significant ‘legacy’ homes are now fully decoupled from general PCL market cycles.
The record-breaking premium paid for The Holme suggests that for the world’s most significant trophy assets, institutional rarity now outweighs broader geopolitical headwinds and serves as a proof-of-concept for the “Flight to Rarity” thesis.
For the buyer, the question was almost never “what’s the discount?” but a decision guided by conviction – knowing that they’re acquiring one of the most significant homes on the global market offering almost untouched legacy, lifestyle, and long-term positioning opportunities.
Who bought The Holme?
An irreplicable home of this calibre, scarcity, and historical prominence was always going to attract the attention of the world’s supremely rich looking for one of the capital’s most important – and expensive – legacy properties.
With the £195 million price tag, £23 million stamp duty fee and six-figure annual upkeep and staffing costs, The Holme’s ownership to a small number of potential global buyers.
In the running are those with royal, political, finance or big tech connections – or institutionally minded family offices after a flagship London home or secondary residence with redevelopment potential.
London’s real estate big players watch and wait
The top end of London’s trophy market is excited; the deal, and premium paid, adds to a flurry of high-profile, ultra-prime transactions that signal London’s status as a global safe haven still holding and a market still moving, despite more tax-friendly carrots being dangled in other global wealth hubs.
Although not the most expensive transaction in London this year, the sale of The Holme stacks up against the sale of a number of ultra-premium homes in the UK capital in the 12 months, surpassing all but one by almost fourfold.
In April, property developer Nick Candy sold Providence House in London’s Chelsea, purchased by Suneil Setiya, the British founder of Quadrature Capital, a tech-driven investment firm based in London, for a reported £265 million (US $350.5 million)
In October 2025, a One Hyde Park five-bedroom apartment tied to bankrupt Hong Kong property tycoon Pan Sutong was put on the market for £45 million.
Later that month Star Wars creator George Lucas bought a £40 million St John’s Wood mansion – usurped by Nigerian businessman and philanthropist Femi Otedola’s acquisition of a 10-bedroom mansion of Avenue Road, also in St John’s Wood, earlier in the spring.
Signalling a positive start to 2026, xAI co-founder Igor Babuschkin purchased a five-bedroom penthouse in Bayswater’s ultra-prime Park Modern development for £57 million in February, a rumour which he denies.
In what will be one of the UK capital’s headline transactions this year should the property reach the £175 million asking price, a five-bedroom penthouse at One Hyde Park is on the market with Sotheby’s International Realty.
Becky Fatemi, executive partner at Sotheby’s, said that the penthouse is likely to be “the next major trophy asset to be snapped up” following the bellwether acquisition of The Holme.
Inside The Holme – what we know
So what will new owners inherit? There are few publicly available images of The Holme, but it is understood that the 29,000 square foot (2,694 square metre) mansion has approximately 40 bedrooms.
New owners will also inherit eight garages, a tennis court, sauna, whirlpool, grand dining room, a ballroom and library.
The residence sits on 1.6 hectares (4 acres) of gardens, parin touching distance of the park’s boating lake and moments from London Zoo.
New owners will count the US ambassador as a closer neighbour, residing at nearby Winfield House
The property was called “the ultimate desirable residence” by the BBC when it went on the market for £30 million in 1988 and described as “possibly the world’s most expensive home”.
The freehold for The Holme in Regent’s Park is owned by the Crown Estate and has been made available to buy on a long lease.
