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.

14. Pensmore, United States — 72,000 sq ft
Dreamed by multi-millionaire astrophysicist and ex-CIA agent Steve T. Huff, Pensmore is one of the biggest houses in the world—and perhaps one of the sturdiest.
The reinforced-concrete, chateau-style home is located in the Ozark Mountains and is meant to be resistant to everything from bomb blasts to natural disasters.
There are 14 bathrooms, 13 bedrooms, a music room and a 1,600 square-foot library, and space for a history museum. Pensmore has been under construction on and off for over a decade… and counting. There’s no telling when or if it will ever be completed.
| Size: | 72,000 sq ft / 6,689 m2 |
| Location: | Highlandville, Missouri |
| Estimated value: | $10 million |
| Owner: | Steven T. Huff |

13. Taohuayuan, China — 72,400 sq ft
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.
| Size: | 72,400 sq ft / 6,700 m2 |
| Location: | Suzhou, China |
| Estimated value: | $154 million |
| Owner: | Hongtian Chen |
| Built in: | 2016 |
12. 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 the most expensive house on the French Riviera, and dip in one of its 12 pools, walk through the extensive gardens, or check out the commercial greenhouse.
If the luxury mansion looks familiar, that’s because it appeared in Alfred Hitchcock’s movie To Catch a Thief.
| Size: | 80,000 sq ft / 7,400 m2 |
| Location: | Villefranche-sur-Mer, France |
| Estimated value: | $750 million |

11. La Reverie, United States — 84,600 sq ft
What happens when you start one of the most popular hair product companies? You build huge mansions with everything you want.
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.
| Size: | 84,600 sq ft / 7,900 m2 |

| Estimated value: | $111 million |
| Owner: | Steven Schonfeld |
| Built in: | 2001 |
10. Modern Versailles, United States — 85,000 sq ft
As you can imagine, constructing America’s largest family home is a monumental task. Situated in Florida’s exclusive Orange County, this mega mansion is inspired by the Palace of Versailles in France. It began construction in 2004 and is expected to complete in 2023.
What is the payoff for such a long wait? How about an 8,000 sq ft master bedroom, 11 kitchens, outdoor and indoor pools, a wine cellar, two tennis courts, and a 35-car garage? Two elevators are on the luxury 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.”
| Size: | 85,000 sq ft / 7,900 m2 |
| Location: | Windermere, Florida, USA |

9. Witanhurst, United Kingdom — 90,000 sq ft
The second-largest home in the United Kingdom, Witanhurst, was designed by architect George Hubbard and built over a century ago. (The original estate was named Parkfield in 1774).
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 on three floors, gym, sauna, movie theater, and billiards room. Hopefully, its relatively new owner will keep up with the maintenance better than the previous ones.
| Size: | 90,000 sq ft / 8,400 m2 |
| Location: | London, UK |
| Estimated value: | $450 million |
| Owner: | Safran Holdings, Andrey Guryev |
| Built in: | 1913 |
8. The One, United States — 105,000 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 luxury mansion 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: | 105,000 sq ft / 9,755 m2 |
| Location: | Bel Air, California, USA |
| Estimated value: | $141 million |
| Owner: | Richard Saghian |

7. Fair Field, United States — 110,000 sq ft
Owned by businessman Ira Rennert, Fair Field is a marvelous Italian Renaissance-style mega mansion located in the Hamptons. The main residence is 62,000 square feet, but the entire complex has several buildings that amount to 110,000 square feet. To put that into perspective, it is twice the size of the White House.
As one of the biggest private homes in America, it comprises 29 bedrooms, 39 bathrooms, three pools, a bowling alley, a 164-seat theater, and a garage for 100 luxury cars. The luxury estate even has its own power plant.
It’s also a mega-mansion mired in controversy that inspired a novel—James Brady’s The House That Ate the Hamptons.
| Size: | 110,000 sq ft / 10,219 m2 |
| Location: | Sagaponack, NY, USA |
| Estimated value: | $250 million |

6. Safra Mansion, Brazil — 117,000 sq ft
Located in the prestigious Morumbi suburb of Sao Paulo, Brazil, the Safra Mansion is tucked behind a large set of security gates. Unfortunately, for those curious about the details of this huge mansion, not much is publicly available.
We do know it boasts a massive 117,000 sq ft of space with at least 130 rooms and multiple pools.
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.

| Estimated value: | Unknown |
| Owner: | Vicky Safra |

5. 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 biggest home in America takes inspiration from French châteaux (castles), 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 of this luxury house looks like? Good news. Public tours of the massive estate are available, along with lodging for guests on the same property.
| Size: | 175,000 sq ft / 16,300 m2 |

His 27-story skyscraper towers over the neighboring buildings and is filled with the epitome of luxurious touches. The luxury home includes a rooftop helipad with space for three helicopters, enough parking for 168 of his favorite rides (including some of the world’s most expensive cars), and several guest apartments.
But what billionaire’s luxury home would be complete without an indoor swimming pool, a theater, and multiple spas and gyms? Not this one. Oh yeah, it also has a staff of 600 people to handle operations.

As home to the reigning monarch of the United Kingdom, Buckingham Palace is certainly one of the most recognizable royal residences in the world. It has been a staple of global culture and politics for over three centuries. It also has a literal connection to the Houses of Parliament through an underground tunnel.
The most expensive house in the world, Buckingham Palace has 19 staterooms available to host any dignitary, while the 775 rooms and 78 bathrooms ensure that no one feels cramped.
Unlike most on this list of the biggest houses in the world, public tours of the 48-acre Buckingham Palace Gardens and parts of the interior are available. Just make sure to book your tickets well in advance.
