The most expensive home in Europe is Witanhurst in London, reportedly worth up to $450 million, with Monaco’s Tour Odéon penthouse close behind at an estimated €380 million. This ranking covers homes in Europe by recorded sale price or reported value as of October 2026, and includes one 2026 deal in Chelsea reported at more than £270 million. Royal palaces are not ranked because they are not on the market.
| Rank | Name | Price or value |
|---|---|---|
| 1 | Witanhurst, London | $450 million (reported value) |
| 2 | Tour Odéon Sky Penthouse, Monaco | about €380 million (estimate) |
| 3 | Providence House, Chelsea, London | £270 million plus (reported) |
| 4 | Château Louis XIV, Louveciennes, France | $301 million |
| 5 | The Hyde Park Mansion, London | £210 million |
| 6 | Hôtel Lambert, Paris | more than €200 million |
| 7 | Park Place, Henley-on-Thames, UK | £140 million |
| 8 | Villa Les Cèdres, Saint-Jean-Cap-Ferrat, France | about €200 million (2019 deal) |
| 9 | The One Hyde Park Penthouse, London | £160 million ($209 million) |
| 10 | The Knightsbridge Apartment, London | £90 million |
1. Witanhurst, London: $450 million (reported value)
Witanhurst in Highgate is the second-largest private residence in London after Buckingham Palace, with 65 rooms across three floors, including 25 bedrooms, and a huge basement extension that reportedly adds tens of thousands of square feet. The family of Russian businessman Andrey Guryev bought it in 2008 for £50 million, after the previous owner paid £32.5 million in 2007.
The reported value of up to $450 million is an estimate, since the house has not traded since. Our ranking treats it as a valuation, ahead of the Monaco penthouse, because of the land and floor area.
2. Tour Odéon Sky Penthouse, Monaco: about €380 million (estimate)
The multi-level penthouse crowns the Tour Odéon, which opened in 2015, and spans roughly 3,300 square meters. A July 2025 report put its value around €380 million, and early asking prices had ranged from €300 million upward. We found no confirmed sale.
Our figure tracks the 2025 estimate, and we treat asking prices as a ceiling, since listings of this size rarely close at the first number.
3. Providence House, Chelsea, London: £270 million plus (reported)
This Grade II-listed mansion sits on roughly two acres with a lake and a swimming pool. Property developer Nick Candy sold it in an off-market deal reported in April 2026 for a price reported at between £265 million and £275 million. No public record has confirmed the buyer.
If the price holds, it would beat the £210 million paid in 2020 for a Hyde Park mansion as the biggest UK house sale. We list it as reported because no public record had confirmed the price when we checked.
4. Château Louis XIV, Louveciennes, France: $301 million
The château looks like the 17th century but was built between 2008 and 2011 on a 57-acre walled estate near Versailles. Saudi Crown Prince Mohammed bin Salman bought it in 2015 for $301 million, a price widely reported as a world record for a home at the time.
The sale price is the figure that counts here.
5. The Hyde Park Mansion, London: £210 million
A 45-room mansion overlooking Hyde Park changed hands in 2020 for £210 million, which at the time of the sale was about $270 million. It remains one of the highest prices ever recorded for a UK house.
6. Hôtel Lambert, Paris: more than €200 million
Louis Le Vau designed the mansion on the Île Saint-Louis for financier Jean-Baptiste Lambert between 1640 and 1644. Prince Abdullah bin Khalifa Al Thani paid a reported €80 million for it in 2007 and spent a reported €120 million restoring it. French billionaire Xavier Niel bought it in 2022 for more than €200 million, about $226 million, reportedly as a home for his cultural foundation.
7. Park Place, Henley-on-Thames, UK: £140 million
The stately home near Henley-on-Thames sold in 2011 for £140 million, then the record for a UK house sale, equal to roughly $225 million at that time. The figure comes from the price reported when the house changed hands.
8. Villa Les Cèdres, Saint-Jean-Cap-Ferrat, France: about €200 million (2019 deal)
The Riviera villa stands on 14 hectares at Saint-Jean-Cap-Ferrat and dates to about 1830. King Leopold II of Belgium once owned it, and Campari inherited it with its 2016 purchase of Grand Marnier. In August 2019 Campari announced a preliminary agreement to sell it for €200 million to an unnamed buyer, with closing expected that October. We found no record of the final closing, so we hedge the figure.
9. The One Hyde Park Penthouse, London: £160 million ($209 million)
A penthouse in the One Hyde Park development went to an offshore buyer for £160 million, or $209 million, a price reported as the highest for a home in Britain when it closed. It is an apartment, not a house, and the price was recorded at the time of sale.
10. The Knightsbridge Apartment, London: £90 million
Land Registry records list a £90 million flat in Knightsbridge as the UK’s priciest apartment sale on record. The year is not stated in the source we used. It is the cheapest entry on our list, at about $115 million.
Special mentions
Buckingham Palace and Kensington Palace were on our old list, with values near $1.5 billion and $230 million. Both are royal residences with no market price, so we leave them out of the ranking.
