No. 1: Antilia
Antilia, located in Mumbai, India, is 2013’s most expensive residence. The 27 storey high mansion features pretty much anything you can think of, from a health floor and a six storey parking lot to a ballroom and a 4 storey garden. Not surprisingly, its owner, Mukesh Ambani, is the world’s fifth richest man. This modern looking palace is estimated at a breathtaking $1 billion.
