Your home is such an integral part of your life. It is where we spend a great deal of our time. It's where you raise your children and create memories. For others, it's where you put your exorbitant wealth on full display. While most of us just hope to keep a roof over our heads and have a garage for our car, these homes are on another level. Here are some of the most expensive homes in the world.

Most Expensive Homes in the World 

1. Buckingham Palace

The residence of the British royal family, the value and actual liquidity of Buckingham Palace could be highly debated. However, this is the official home of Queen Elizabeth, and as such, it's a pretty expensive home. Some have valued the palace at $4.7 billion. Of course, this one is a tough to gauge, as it will likely never be on the market. The palace and grounds are part of a royal trust, and aren't really accessible by anyone. Some sources say Buckingham is more in the range of $1.5 billion. It would likely be very difficult to find someone to buy it for that figure. Purely for the scale and theoretical value, Buckingham Palace has to be at the top of any list.

2. Antilia

The futuristic home of the richest man in India, Antilia reportedly cost $1 billion to build. Head of Reliance Industries Limited, Mukesh Ambani is presumed to be worth of over $49 billion, according to Forbes. The residence is much like an abstract skyscraper, with pillars and fascinating angles. The building has 27 stories, with enough room for 168 cars and three helicopters. And to think that many of us are content with getting to park our car in a garage at all.

3. Bill Gates' Lake Washington Home

While his home may not be the most expensive in the world, there few rivals when it comes to Bill Gates' personal net worth. The main beneficiary and protagonist of our modern computer age, Bill Gates can pretty much buy whatever he wants. Based on where he built Xanadu, he really values a good view. Located in Medina, Washington, on Lake Washington, this house sits east of Seattle.

While built in a rustic nature and appearance, the house is reportedly a veritable computer. With climate control systems, temperature regulation efficiencies to reduce waste, and the ability to change the paintings on walls with the press of a button, the house's rustic look is pretty deceiving. Worth around $127 million, it pales in comparison to other residences in terms of price, but makes up for it in pristine outdoor locations and tech galore.

4. Witanhurst, London

This is a mysterious destination. Witanhurst was purchased by a wealthy Russian billionaire in 2008. The purchase was done through a shell company, and kept very hush hush. Challenged by only Buckingham Palace, Witanhurst is the second largest residence in London. Originally built by the heir to a soap fortune, the mansion is now being renovated. These "renovations" have included adding a massive 40,000-square-foot basement, a swimming pool, and a new guest house. Once completed, it's estimated that this place will be worth $450 million.

5. Odeon Tower Penthouse

If Monaco doesn't scream extravagance and ultra wealth, what does? The extremely small kingdom has some incredible real estate if you can get your hands on it. Odeon Tower seems to be one of the crown jewels of real estate here, with the penthouse reportedly expected to be listed for $400 million. The penthouse has five levels, and 35,500 square feet. In a country with zero income tax, and pretty strict financial guidelines for moving there, this is definitely a place where money talks.

6. Villa Leopolda

Estimated at $750 million, Villa Leopolda is the stuff of movies. Built by the king of Belgium in 1902, the estate was a gift to one of his mistresses. You can't make this stuff up. The 14 bedroom villa was almost purchased by a Russian billionaire back in 2008, but the deal fell through. Nestled in the French Riviera, this one is absolutely beautiful.

7. Chartwell

A Los Angeles mansion once used in "The Beverly Hillbillies", Chartwell is a limestone mansion built in 1933 by famed architect Sumner Spalding. Listed back in October of 2018 for $245 million, this property actually got a price cut from $350 million. The beautiful property has a 75-foot swimming pool, poolhouse, and the entire grounds are styled in French style that would make any owner feel like an aristocrat.

8. Kensington Palace Gardens

Actually a street in London, this location is easily the most expensive strip of real estate in the country. Owning a home on this street will cost you an average hit of $40.8 million.  Every single "home" looks like something out of a Victorian-era movie. A stone's throw away from the actual Kensington Palace, a homeowner here is right in the heart of an area of London that is heavily bolstered by the endless count of royal locations and history, as well as the political center of the country.

9. Beverly House, Beverly Hills

The pinnacle of Beverly Hills real estate, the Beverly House was listed last fall for $135 million. If you're a movie buff, this is pretty much the coolest thing ever. Scenes from "The Godfather" were shot here. Remember that whole horse head in the bed? It was also a filming location for "The Bodyguard." The property has a massive array of swimming pools and sculptures. Coupled with dozens of bedrooms and bathrooms, you could probably have the biggest party of your life at this place. Even John F. Kennedy spent his honeymoon here.

10. Fleur De Lys, Los Angeles

The mansion sold for $102 million in 2014. A relatively younger build, the Fleur De Lys was completed in 2002. It proved difficult to sell, as $100 million dollar homes aren't exactly the most in demand entity on the market. First listed in 2007, this giant has 12 bedrooms and 15 bathrooms. If you like fancy tennis courts, swimming pools, and ornate gardens, it's probably  worth the mortgage......

11. Daniel Loeb's Penthouse, 15 Central Park West

This is expensive real estate. To own space at this address is to be in the presence of some of the wealthiest and most powerful people in the world. The investment in the construction of the building has been incredibly lucrative, and the values of the apartments continue to rise. Hedge fund titan Daniel Loeb paid $45 million for the 10,700 square foot penthouse. That might sound absurd to those like me, but New York titans seem set to pay any price to own the popular real estate along Central Park.

12. Fair Field, Sagaponack, New York

Largely opposed by neighbors in the Hamptons, banker Ira Rennert built the grand Fair Field on just under 1½ acres of land. That's a big house folks. In fact, the property has multiple houses, garages, and buildings of the like. Estimates have the number of bedrooms and bathrooms at 21 and 18. The property began construction in the 1990s, and has a garage big enough to hold over 150 cars. Reportedly worth nearly $250 million, this is an expensive locale.
