Talking about luxury homes, check out the world’s first billion-dollar home. It’s more of a high-rise hotel than a house, but this home is meant for Mukesh Ambani, the fifth richest man in the world, his wife and three children. It’s a 27-story skyscraper in downtown Mumbai with a cost nearing $2 billion. When the Ambani residence is finished, after a four-year process, it will be 550 feet high with 400,000 square feet of interior space. The Ambani home, called Antilla, is set to have six stories of parking lots, a lobby with nine elevators, a ballroom, a health level with an ice room where guests can escape the Mumbai heat with man-made snow, a four-story open garden and entertaining spaces for the business guests. Lest you be fooled into thinking this is actually a hotel, the Ambanis will live in it, and only occasionally use the residence for corporate entertainment. They look and feel of the home’s interior will be distinctly Indian.
