But what about the expensive houses where the rich and famous live?
Here are the 7 most expensive mansions in the world

1. Buckingham Palace
Buckingham Palace expensive home
It’s no surprise that a palace fit for a queen (literally) tops our list. At $2.9 billion, Buckingham Palace is the most expensive home in the world.

But Buckingham Palace is more of a historic landmark than a home.

In case you didn’t know, the palace is owned by the British Royal Family and has been the residence of the monarch since 1873. The palace has a breathtaking French neoclassical architectural design, which was favored by King George IV.

The Buckingham Palace we see today was designed by architect John Nash in 1826. There are three wings of the palace that surround a central courtyard.

Queen Elizabeth II currently lives here, though her spouse and children live elsewhere.

There’s a reason this palace comes with such a huge price tag. The palace is a whopping 828,000 square feet! It boasts 775 rooms, 78 bathrooms, 19 staterooms, and 92 offices. Even the garden is 40 acres in size.

You can find the palace in Westminster, London, and is the perfect photo op for London tourists.

2. Antilla
If you’re wondering where India’s richest man lives, he resides at the second-most expensive house in the world.

Antilla is worth $1 billion and Mukesh Ambani calls this home. Ambani is the Chairman and Managing Director of Fortune Global 500 Company Reliance Industries Limited.

The building is located in Mumbai’s Cumballa Hill, in the middle of the city. It’s 400,00 square feet and a staggering 27 stories high. The building was designed by architecture firm Perkins & Will and hospitality design firm Hirsch Bender Associates.

The home has a very modern design and no two rooms look the same.

Antilla is more like a resort — the house has a 50-seat movie theater, three helipads, a health spa, a ballroom, a salon, an ice cream room, and a yoga studio. They even devote six stories to car storage and host a car service center within the home.

Mukesh Ambani lives in the house with his wife, Nita, and their three children. They also host a 600-person staff to ensure everything runs smoothly.

3. Villa Leopolda
What’s better than owning a million-dollar home? Owning a million-dollar home that sits on France’s picturesque Cote d’Azur. This is the home that Lily Safra owns, who inherited the home from her widow, Lebanese-Brazilian banker Edmund Safra.

The mansion occupies 50 acres worth of land, has 11 bedrooms, 14 bathrooms, helipad, commercial greenhouse, an outdoor kitchen, and an incredible swimming pool. A home this luxurious also boasts a hefty price tag: $750 million.

The home has a bit of fame and history before it was owned by the Safras.

Villa Leopolda was originally owned by King Leopold II of Belgium. It has been redesigned since then; in 1920, American architect, Ogden Codman Jr., used inspiration from the period’s Belle Epoque trend to give the home its classic flair.

The home also has another major historic element — it was the setting for Alfred Hitchcock’s film To Catch a Thief.

4. Villa Les Cedres
In fourth place, we have another French home purchased by King Leopold II.

This home is located in Saint-Jean-Cap-Ferrat and is worth $450 million. The home was built on 35 acres of gardens. The home has 14 bedrooms, a stable big enough to fit 50 horses, and a massive swimming pool.

There’s plenty of art and culture in this home. You’ll find décor staples such as gilded woodwork and crystal chandeliers as well as cultural pieces such as 19th-century oil paintings and a library that hosts 3,000 books.

5. Les Palais Bulles
Les Palais Bulles translates to “bubble palace” in English, and you’ll understand why when you see this mansion.

The house is adorned with multiple round rooms that overlook the Mediterranean — looking more like multiple bubbles than an actual house.

Hungarian architect Antti Lovag designed this home during the later part of the 20th century. The home has many exquisite features, including numerous gardens, three swimming pools, and a 500-seat Amphitheatre.

Italian fashion designer Pierre Cardin currently owns the house — however, he only uses it as a vacation home. Les Palais Bulles is mainly used for parties and events.

6. The Odeon Tower Penthouse
If you have $330 million to spare, you can buy a 35,000 square-foot apartment in Monaco’s most expensive building.

Odeon Tower Penthouse looks more like a lavish resort than a penthouse — the most defining feature is a 360-degree infinity pool with water slides. The penthouse is currently the most expensive apartment in the world.

Alexandre Giraldi designed the tower with Group Mazococo. The penthouse has a completely modern and futuristic look and there’s a private elevator leading to the penthouse.

7. Four Fairfield Pond
Four Fairfield Pond is the most expensive home in New York City. It’s located at oceanside, facing the Atlantic Ocean. Its distinct French-manor style gives this mansion a sophisticated look, but its features are nothing short of glamorous.

The home is 63 acres in size and hosts 29 bedrooms, 39 bathrooms, a basketball court, a 91-foot dining room, squash courts, bowling alley, three swimming pools, a garage large enough to hold 100 cars, and tennis courts.

This home even has its own power plant.

And how much does this all cost? $248 million.
