#2. Antilia – $1 billion
Named after a mythical island, the only thing mythical about this building is its price. Owned by Indian
billionaire Mukesh Ambani, this 34-story home is designed to withstand earthquakes, and it contains three helipads and a parking garage that holds 160 cars. Due to its mammoth size, the building requires 600 full-time staff members to keep it running.
