13. Seven The Pinnacle, USA — $155 million

Located in Montana, at Yellowstone Club, surrounded by tall trees, Seven The Pinnacle is the largest property with a private golf course and ski community in the USA—and indeed in the world.

12. Gemini, USA — $173 million

This is the most expensive house ever sold in Florida. Software billionaire and Oracle founder Larry Ellison bought the Palm Beach ocean-to-lake estate in June 2022 for $173 million. There are multiple houses on the Gemini estate, with a total of nearly 85,000 square feet of living space, inside and out, with 33 bedrooms, 34 bathrooms, and 13 powder rooms on the 15.65-acre property.

11. Palazzo de Amore, USA — $195 million

This Mediterranean-style estate was built in 2014 and was regarded as the most expensive residential complex in the United States back then. The Palazzo de Amore looks expensive just by looking at its surrounding, which is based in Beverly Hills and has the spectacular view of Los Angeles. Owner Jeff Greene more than doubled the value of the property after internal and external renovations. The luxury mansion boasts a 15,000-square foot entertainment center, 12 bedrooms, 25 bathrooms, a Turkish spa, a 50-seat movie theater, a bowling alley, a disco—and even a hillside vineyard.

10. Ellison Estate, USA — $200 million

This address is a collection of Japanese-style houses inspired by Japanese imperial design, inside one giant property, alongside a man-made lake, a tea house, a koi pond, and a bathhouse. Inspired by Japanese imperial design, this estate sits on 23 acres and features an 8,000-square-foot home.  Billionaire Larry Ellison, 78, owns more than one house of course!  Located in Woodside, California, this rather intriguing waterfront property is set inside a gated community and is designed to settle into its surroundings, with a lodge-style design. In 2020, Ellison moved permanently to the Hawaiian island of Lanai, which he bought for $300 million in 2012. Not bad for the son of a single mother from the Bronx!

9. Beyoncé & Jay Z’s Malibu Mansion — $200 millions

This behemoth home spreads over 30,000 square feet and cost the music moguls $200 million in 2023—which was a fair deal less than the $295 million it was first listed for. Designed by award-winning Japanese architect Tadao Ando, the home is an architectural minimalist marvel, with no expenses spared. It features enormous hallways, manicured lawns, and floor-to-ceiling glass walls. The distinct concrete residence epitomizes Tadao Ando’s signature ‘critical regionalism’ philosophy, thus the glass walls with Pacific views. The address is located on ‘Billionaires’ Row’ and Stevie Nicks, Pamela Anderson, Matthew McConaughey, and Betsy Johnson are among the stars who also own property in the neighborhood. Tadao Ando is the only architect ever to have won architecture’s four most prestigious prizes: the Carlsberg, Praemium Imperiale, Pritzker, and Kyoto Prizes, which is extremely impressive for a self-taught architect.

8. 18–19 Kensington Palace Gardens, UK — $222 million

This luxury property owned by Indian steel magnate Lakshmi Mittal was renovated using the same marble as that used to build the Taj Mahal! In one of the most elite streets in the whole of the UK, this neo-Georgian mansion went for $90 million in the 1990s and was carefully renovated, at a cost of another $90 million, to its current splendor. It took about five years to complete the garden and needed around 400 workers each day to finish it. Inside the property, there’s actually a bespoke hairdressing salon, an indoor swimming pool, steam showers, a spa, and saunas as well as parking for 20 cars. These exclusive houses used to be home to the Rothschilds and Reuters families and can provide a reception for up to 1,000 people, and seated dinner for 250. The property comprised around 55,000 sq feet.

7. Four Fairfield Pond, USA — $250 million

American billionaire businessman, 89-year-old Ira Rennert’s incredible Italian Renaissance–style home is named after the adjoining body of water on the property.

6. The Odeon Tower Penthouse, Monaco — $330 million

This property is known as the world’s most expensive flat! The 170-meter-high Tour Odeon, with its 48 floors, is destined to become the new leading light in the Monaco skyline and Europe’s tallest residential skyscraper. Completed in 2015 to be sitting at the top of this skyscraper, this penthouse includes 38,000 square feet of premium real estate space spread across five levels, with five kitchens located on each floor, five main bedrooms, and a few staff bedrooms to boot. Overlooking the beautiful coastline of the Principality of Monaco, with the Ligurian Sea and Larvotto Beach below, the Odeon is an unprecedented example of extreme luxury.  It has a 360-degree infinity pool, complete with a water slide for those who like to swim salt-free. It’s got a dance floor, a luxurious bathroom, and even the parking space is believed to cost around $330,000. The owner is currently anonymous. 

5. Les Palais Bulles, France — $420 million

The Palais Bulles (or Bubble Palace) on the French Riviera is different from your run-of-the-mill ordinary multi-million-dollar home. It is one massive, 13,000 sq ft terracotta-colored bubble! A view from the sky reveals a series of circular buildings, and the circle theme continues in the internal designs. There are round rooms, cylindrical beds, artwork, and swimming pools. Hungarian architect Antti Lovag designed the home which features ten suites opulently decorated by various contemporary artists. Antti Lovag apparently hated straight lines as “an aggression against nature”. Since the last notable owner´s death in 2020, French fashion designer Pierre Cardin, the entire estate is available to rent through Société de Gestion Pierre Cardin, but not (yet) available for lease-signing. Located at Théoule-Sur-Mer near Cannes, Les Palais Bulles has hosted many fashion and celebrity events since Cardin bought the property in 1992.

4. Villa Les Cèdres, France — $450 million

Another luxury French estate appears in this list—the Villa Les Cèdres, named after its cedar tree setting. The mansion was once owned by King Leopold II of Belgium—and regal it is! It is set in 35 acres in Saint-Jean-Cap-Ferrat in the South of France and was built around 1830. The home is about 18,000 sq ft and was bought by Ukrainian billionaire and businessman Rinat Akhmetov in 2019. Overlooking the Mediterranean Sea, the mansion has multiple balconies from where you can see the lush gardens—15,000 plants and 20 greenhouses. It has a stable with room for up to 30 horses. There are innumerable rooms and shared spaces in this royal residence, a stunning ballroom, and an Olympic size swimming pool. As of April 2023, Akhmetov was listed as the 460th richest person on the planet (and the richest Ukrainian) with an estimated net worth of $5.7 billion.  Since the beginning of the Ukraine war started by Russia in February 2022, he has lost two-thirds of his fortune, including steel, energy and agricultural assets. The Russians have destroyed about 70 companies owned by Akhmetov.

3. Villa Leopolda, France — $750 million

Named after its previous owner, King Leopold II of Belgium, (again he appears in this list, he was one wealthy real estate aficionado!) this property is the most expensive private residence in Europe. Was designed by Ogden Corman Jr. an American architect and was built between 1929 and 1931. The architect borrowed the style from the Belle Époque. The home has seen numerous elite owners in the French Riviera and has also been used as a film set, for Alfred Hitchcock’s 1995 “La Main Au Collet” (To Catch a Thief). Lily Safra (nicknamed ‘The Gilded Lily) was the socialite widow of Lebanese-Brazilian banker Edward Safra, and she inherited the property after his death in 1999. Lily passed away aged 87 in July 2022 and her descendants now own the villa. There are 80,000 square feet of space, a huge swimming pool, and luxuriant gardens that apparently require the work of more than 50 gardeners every day.  Villa Leopolda has 11 bedrooms, 14 bathrooms, a commercial greenhouse, a helipad, and an outdoor kitchen. 

2. Antilia, India — $2 billion

Moving from Europe to Asia, the current second most expensive home on the planet (and priciest PRIVATE residence) is Antilia, the Mumbai residence named after a mythical island in the Atlantic. The land it is built on is used to house an orphanage. Antilia was designed by two US architecture firms: Perkins & Will, in Chicago, and Hirsch Bedner Associates, in Los Angeles, and construction started in 2006 and took four years. The interior design uses the shapes of the lotus and the sun. Owned by Mukesh Ambani, India’s richest person, is the proud owner of Reliance, an oil and gas firm and the second-biggest company in India. This 400,000-square-foot 27-floor building has an entire six floors dedicated to parking for the family´s guests! The 27 floors have double-high ceilings, so the building is really as high as 54 stories. It is designed to withstand earthquakes. As well as space for hundreds of staff, Antilia features a huge temple, luxurious guest suites, three helipads, an ice-cream parlor, a yoga studio, a health spa with indoor pools, a ballroom, and a movie theater. It even has a “snow room” where the family can cool off with snowflakes if India’s summer temperatures get a little too much!

1. Buckingham Palace, United Kingdom — $4.9 billion

King Charles III, in right of the British Crown, owns this Neoclassical-style Palace, valued as the most expensive home in the world at $4.9 billion. Located in central London between Mayfair and Belgravia and near Hyde Park, The Palace was synonymous with the late Queen Elizabeth II who reigned for more than 70 years. It is highly unlikely to be on the market in the foreseeable future as it is the current British Royal Family´s home, and the administrative headquarters of the monarch of the United Kingdom, and that institution is very much alive. Buckingham Palace contains a massive number of rooms— 775 of them, including 92 offices, 19 staterooms, and 78 bathrooms. It is said by some that a few other secret rooms can be found on the premises too! It is open to the public for guided tours. This huge luxury mansion in central London is spread over around 77,000 square meters. The building at the core of today’s palace was the Duke of Buckingham´s large townhouse built in 1703. Buckingham Palace became the London home of the British monarch when Queen Victoria was crowned in 1837. The Palace also has a doctor’s surgery, cinema, post office, swimming pool, and jeweler’s workshop.
