The home's annual maintenance costs exceed $1.2 million, reflecting the preservation demands of its waterfall site.

The One in Bel Air is the largest private home ever built in America, at 105,000 square feet completed in 2022 after a decade of construction. This mega-mansion features 21 bedrooms, 42 bathrooms, a 30-car garage, a 400-foot outdoor track, a nightclub, a 4D cinema, five pools, a beauty salon, and a helicopter pad. Annual property taxes exceed $1.5 million.

Casa Mila, Antoni Gaudi's 1912 stone quarry-inspired masterpiece, contains 32 interlocking apartments with floor plans where no two rooms are rectangular, challenging conventional architecture.

Hearst Castle, built by architect Julia Morgan between 1919 and 1947, was the largest private home in the U.S. during its construction, with a 90,080-square-foot main house featuring 38 bedrooms and 41 bathrooms.

Versailles redefined royal excess, with 2,300 rooms, 1,800 fountains, and the 73-metre Hall of Mirrors—all designed to awe dignitaries. Peak construction employed 36,000 workers and consumed an estimated 6% of France's entire national budget. Though its political role ended in 1789, Versailles still operates 1,800 fountains daily during summer shows, a feat of hydraulic engineering that cost over 10 million livres in its own era.
