Some people want their home to serve as a place for collecting treasured items. Others desire the ultimate space to host parties and enjoy life to the fullest. But for the biggest houses in the world, limits do not exist. They can easily do both, along with so much more.
Whether it’s a 27-story skyscraper with 600 people on staff or a centuries-old palace ready to host the most prestigious dignitaries, the largest houses in the world have everything it takes to impress.
Master bedrooms stretch to nearly 10,000 sq ft, while bowling alleys, 100-car garages, and multiple pools are just the tip of the iceberg. And really, what is a big home if you can’t invite over 5,000 people to enjoy your banquet hall?
Covering nearly every corner of the globe, the world’s biggest houses are ready for anything you can throw at them. With plenty of room left over.

Some of the world’s biggest houses are perfectly situated for large parties and energetic fun. This one, on the other hand, is built on a lake island with stunning views and peaceful surroundings.
This huge mansion rivals some of the biggest houses in America, but features distinctly Chinese architecture, even going as far as using the Classical Gardens of Suzhou, a UNESCO heritage site, as inspiration. It’s no wonder they chose a name that translates to utopia.
Taohuayuan features 32 bedrooms and bathrooms, an enormous wine cellar, and a lakeside pool.

The One, United States — 74,000 sq ft
When Nile Niami set out to create one of the biggest mansions in the world, his goal was to create something that only a select few people can afford. The type of people who want something no one else has.
And after many legal challenges, the feat has been accomplished. But due to Bel Air’s latest zoning regulations, it’s unlikely to be repeated in the area ever again.
Featuring a four-lane bowling alley, a 45-seat movie theater, and a full indoor/outdoor nightclub with a VIP section, The One is ready to host extravagant parties, all without leaving the comfort of your home.
This beautiful, big house also has a 5,000 sq ft master bedroom to stretch out in, and a garage with enough space to hold a museum’s worth of expensive cars.
Size: 74,000 sq ft / 6,900 m2 Location: Bel Air, California, USA Estimated value: $500 million Owner: Nile Niami Built in: 2013
Villa Leopolda, France — 80,000 sq ft
The French Riviera is known as a stunningly beautiful location with jaw-dropping views and gorgeous water. It’s also known as a playground for the wealthy, and Villa Leopolda might be the perfect manifestation of that thought.
With 19 bedrooms and 14 bathrooms spread across the main building and two guest houses, there is more than enough space for all of the fun you can imagine.
If the interior doesn’t do it for you, step outside and dip in one of the 12 pools, walk through the extensive gardens, or check out the commercial greenhouse.
Size: 80,000 sq ft / 7,400 m2 Location: Villefranche-sur-Mer, France Estimated value: $750 million Owner: Mikhail Prokhorov Built in: 1931

Sydell Miller hired architect Jeffery Smith to design one of the biggest houses in the US in an ideal Palm Beach location, with almost 350 feet of oceanfront coastline. It exchanged hands in 2019, purchased by hedge-fund manager Steven Schonfeld.
As one of the biggest houses in America, it has ten rooms, an opulent library, and a basement with a bowling alley and game room. The exterior is covered in stone and features large Roman arches over the window and loggia openings.

Modern Versailles, United States — 85,000 sq ft

What is the payoff for such a long wait? How about an 8,000 sq ft master bedroom, 11 kitchens, and a 30-car garage? Two elevators are on the property, one of which is reported to feature extensive use of gold.
In the documentary Queen of Versailles, the Siegels famously said, “We’re sorry we ever started. But we’re $50 million into it, so it really needs to get done.”

Witanhurst, United Kingdom — 90,000 sq ft
The second-largest home in the United Kingdom was designed by architect George Hubbard and built over a century ago.
Before the 2008 sale to Russian businessman Andrey Guryev, it was reported to be in a state of disrepair, showing how the world’s biggest houses are subject to the same laws of time as other homes.
Now, it is ready again to host guests in its 25 bedrooms, gym, sauna, movie theater, and billiards room. Hopefully, its relatively new owner will keep up with the maintenance better than the previous ones.

Perhaps one day, the reclusive Safra family, who also owns one of the world’s most expensive houses, will open the doors to unveil what’s hidden inside one of the largest houses in the world. But until then, you’ll have to let your imagination run wild.

Biltmore Estate, United States — 175,000 sq ft
Built by the well-known Vanderbilt family, the Biltmore Estate has it all. There are an incredible 250 rooms and 43 bathrooms. And if you’re a big reader, then the library with 23,000 books might make you drool even more than the three kitchens.
The design of the largest home in America takes inspiration from French châteaux, complete with a sprawling lawn and multiple gardens. With that much greenery, the two dedicated water sources are a vital piece of the puzzle.
Want to see what the inside looks like? Good news. Public tours of the massive estate are available, along with lodging for guests on the same property.

His 27-story skyscraper towers over the neighboring buildings and is filled with the epitome of luxurious touches. It includes a rooftop helipad with space for three helicopters, enough parking for 168 of his favorite rides, and several guest apartments.

Istana Nurul Iman, Brunei — 2.15 million sq ft
When you’re expecting 5,000 of your closest friends to come over for a party, finding the space might be challenging. Unless you’re the Sultan of Brunei.
The Light of Faith Palace has 1,788 rooms, 257 bathrooms, a mosque with a 1,500-person capacity, and of course, a banquet hall equipped for 5,000 people. The garage is downright massive with 110 spaces, while the air-conditioned stable can hold over 200 horses.
