The world's most expensive home: By the numbers
An Indian billionaire has built what might be history's most lavish private residence — a 600-foot skyscraper in the middle of slum-ridden Mumbai

Indian billionaire Mukesh Ambani is the world's fourth-richest man, so it's hardly surprising that he'd reward himself with luxurious digs. But the oil magnate took things one step further by constructing a home unlike any other in the world — a 27-story tower in the middle of Mumbai. Dubbed Antilia, after a "mythic island in the Pacific Ocean," the imposing structure "resembles a glass and steel Lego stack, interspersed with hanging gardens." The upper floors offer "sweeping views" of the city's sprawling slums and the Arabian Sea in the distance. While local critics have decried Antilia as "an edifice to [Ambani's] ego" and "obscenely lavish," the billionaire insists (via a spokesman) that the new abode simply suits his lifestyle. Here's a look at the key numbers behind Ambani's palace:
