They are located in the same city as Taohuayuan. The Taohuayuan House and its surrounding area are popular because the house was built using Feng-Shui principles.

The interior design comprises 32 bathrooms and bedrooms, in addition to the wine cellar. When it first went up for sale in 2016, it was speculated to be the most expensive home in mainland China, according to Mansion Global.

The Siegels made their wealth in timeshares and chose to build this massive home, which is featured in the documentary Queen of Versailles. They’ve since remarked, notably, “We’re sorry we ever started.” But we’ve invested $50 million in it, so it has to be completed.”

Nile Niami, a film director and real estate developer, has boasted about his 100,000-square-foot Bel Air, California, home, The One, although the entire amount is really made up of a 73,934-square-foot main house and several surrounding structures. Of course, roughly 74,000 is nothing to laugh at. For instance, the White House is just a little under 55,000 square feet, while the 115-room Hearst Castle stands at a comparatively modest 68,500 sq. feet.

For $340 million, the new owner will be able to boast about living next door to Jennifer Aniston. They can also play bowling and feed the ceiling jellyfish while exploring the house’s 20 bedrooms and 30 bathrooms. Despite several appeals, the city denied Niami’s request for a third kitchen for catered events. Neighbors appear to be opposed to the existence of a “party house” in the neighborhood. When inviting friends to sample the wine cellar or relax in the nightclub, the new owner will just have to limit the guest list.
