In the early 20th century, the estate had grown to an impressive size of 3,961 hectares. The property boasts 100 rooms across three floors and includes three elevators, 17 themed bedroom suites, and five salons. Amenities in the compound include stables for 50 horses, a beauty parlor, hammam, and housing for staff members. After Edmond’s death, the home was passed down to various members of the Rothschild family before being sold to the King of Morocco in the 1980s.
In recent years, “The property was purchased by an owner from the Middle East but has never been utilized,” Ignace Meuwissen, cofounder of Whisper Auctions who is handling the sale, told Mansion Global. If Château d’Armainvilliers goes for anywhere near its reported asking price, it will easily claim the crown as the most expensive house in the world. Meuwissen told Mansion Global that the home will likely change hands behind closed doors.
“Most properties we sell are on a whispering basis; the properties change owners mostly confidentiality,” Meuwissen said. There’s already interest from potential buyers, with one from East Europe, three from Asia, and one from Mongolia showing interest in the property.
