5 One Hyde Park (U.K.) – $221 Million
Rounding out the list at number five is the property of Ukraine billionaire Rinat Akhmetov, who has a net worth of $15.4 billion. Unlike the other billionaires on the list, Rinat didn’t purchase a freestanding home. Instead, he spent $221 million on a three-story penthouse apartment in London’s posh One Hyde Park. The apartment is 250,000 square feet and includes such amenities as bulletproof glass and 24-hour concierge service. At the time of its purchase, the apartment was considered the most expensive apartment of all time.
4 Kensington Palace Gardens (U.K.) – $222 Million
As one of several mansions along London’s Billionaires’ Row, steel magnate Lakshmi Mittal’s neo-Georgian home—nicknamed “Taj Mittal”—includes marble from the same quarry as Taj Mahal, 12 bedrooms, swimming pool with gem-encrusted pillars, heated driveway, 20-car garage and his and her studies. Purchased for $222 million in 2008, this is Lakshmi’s third home in Kensington Palace Gardens. He owns two others in the neighborhood. With a net worth of approximately $16.5 billion dollars, it appears Lakshmi has taken up the hobby of house collecting.
3 Fair Field (U.S.) – $248 Million
The third most expensive home in the world belongs to billionaire industrialist Ira Rennert, who has a net worth of approximately $6.5 billion. Ira’s 430,031-square foot Fair Field estate is located in Sagaponack, New York, and has an estimated value of $248 million. The expansive estate has 29 bedrooms, 39 bathrooms, three swimming pools, three dining rooms, basketball court, gym, 164-seat theater, two courtyards and a two-lane bowling alley. There’s even a power plant on site to keep the whole thing running.
2 Villa Leopolda (France) – $750 Million
Apparently, rich people like to name their homes. The second most expensive home in the world is Villa Leopolda, located in the French Riviera. The sprawling chateau sits prominently on 20 acres and is owned by Lily Safra, a Brazilian billionaire who inherited her fortune, currently worth an estimated $1.2 billion. Back in 2008, the philanthropist and socialite put the waterfront property on the market for $750 million. A deal was struck with Russian billionaire Mikhail Prokhorov, who put down a $55 million deposit, only to lose it when he backed out of the deal. Lily still retains ownership of the property, which was originally built for Belgium’s King Leopold II. It is rumored that Villa Leopolda is one of several estates King Leopold built for his mistresses.
1 Antilia (India) – $1 Billion
Mukesh Ambani is the richest man in India, with a net worth of approximately $21.5 billion. As if having all that money isn’t enough, the petrochemical tycoon is also the proud owner of the most expensive home in the world. Located in downtown Mumbai, Mukesh’s 27-story and 400,000-square foot skyscraper is valued at $1 billion. The structure is complete with a six-story underground parking garage, three helicopter pads, movie theater, ballroom, several floating gardens and even a “health” floor (whatever that means) among many other palatial amenities. The compound is rumored to take 600 staff to run and even has a name “Antilia.” Mukesh is married with three children, which begs the question: Is all that space really necessary to raise a family? Even Josephine Baker or Angelina Jolie – internationally known for having large families – never enjoyed that kind of home space.
