Antilia, Mumbai, India
The towering, 27-floor Antilia is the most expensive private residence in the world. It cost the home's owner, businessman Mukesh Ambani, at least $500 million to build.
The design of each floor differs, and the house reportedly has 600 staff members, 168 parking spaces, nine elevators, three helicopter pads, three floors of hanging gardens, and an ice room complete with man-made snow flurries.
The house's ostentation has caused great controversy, with many arguiing that its presence is inappropriate in Mumbai, which is home to some of Asia's worst slums.
