Antilia is home to Reliance Industries chairman Mukesh Ambani – the richest Indian in the world, with a net worth of $27 billion, according to the Forbes India Rich List. The magazine has also predicted that Mukesh Ambani would be the world's richest man by 2014. 52-year-old Ambani has interests in a range of sectors from petrochemicals and textiles to retail. Recently his company has decided to enter into hotels, power, telecom and shale gas projects. In his words, RIL is ready for a "big surge forward" and will use its strong finances for "inorganic" growth and new ventures. (Phot: AP)

Forbes Magazine has said that Ambani began work on this home years ago when "he was worth $43 billion." "Now fully constructed, it's the most ever spent on a home that we know of. In June the world's richest man, telecommunications billionaire Carlos Slim Helu paid $44 million for an Upper East Side Beaux Arts town house. One could interpret the two tycoons' recent moves as a billionaire version of keeping-up-with-the-Joneses," it added. (Photo: AFP)
