While most people are content with having a few thousand square feet to call home, the world’s ultra-wealthy reside in much larger spaces. From modern mansions to historical properties, there are several colossal houses scattered around the world, each with their unique features and amenities. Here are six of the largest houses in the world, starting with the “smallest.” The list excludes places like the Palace of Versailles, which is no longer a residence but now a museum.

6. The One

Located in the elite Los Angeles suburb of Bel Air, The One was purchased by Fashion Nova owner Richard Saghian at an auction in March 2022 for $141 million. Originally listed for $295 million, no one offered anywhere near that sum for the 21-bedroom, 49-bathroom mansion. Developed over a 10-year period by a former film producer named Nile Niami, the property was foreclosed, and the mansion achieved the dubious status of the highest auction price ever for a home in the U.S. The One boasts 74,000 square feet (6,875 square meters) of luxurious space and all the modern amenities, including a nightclub, a 10,000-bottle wine cellar, and a 5,000 square-foot (464 square-meter) master bedroom. It features five swimming pools and a 30-car garage and is considered the largest modern house in America.

5. Villa Leopolda

Villa Leopolda is located in the French Riviera and was originally built by King Leopold II of Belgium. It was then gifted to his mistress, a French teenage prostitute. The stunning 18-acre (7.2-hectare) estate appears in the classic movie “To Catch a Thief” and includes 11 bedrooms and 14 bathrooms. It offers unparalleled views of the Mediterranean, as well as a greenhouse, botanical gardens, and even a helipad. Today, Villa Leopolda is considered the most expensive private residence in all of Europe, with 80,000 square feet (7,432 square meters) of space. It is currently owned by a Russian billionaire who purchased it for $750 million in 2008.

4. Witanhurst

Witanhurst is an expensive private estate owned by Russian oligarch Andrey Guryev and is reported to be the second-largest private residence in London after Buckingham Palace. The Georgian Revival mansion is 90,000 square feet (8,361 square meters) and has 25 bedrooms. It features amenities such as a sauna, 70-foot (21-meter) swimming pool, movie theater, ballroom, and massage parlor. Completed in 1920, it was recently refurbished.

3. Antilia

Antilia, situated in Mumbai, India, is a skyscraper with a 168-car garage that is one of the tallest buildings in the city.

Antilia is the current Guinness World Record holder for the largest house owned by an individual and was designed to survive an earthquake of up to 8 on the Richter scale. The property is managed by a staff of 600 and comprises six floors dedicated to housing up to 168 cars, a movie theater, beauty salon, ice cream parlor, and nine high-speed elevators. Additionally, there is a room that features artificial snowflakes shooting from the walls, and the property cost between $1 and 2 billion to construct.

The palace is valued at $4.9 billion for its 828,000-plus square feet (76,924 square meters) of space.

1. Istana Nurul Iman Palace

Istana Nurul Iman Palace is the official residence of the Sultan of Brunei and the biggest house in the world.
