The richest man in India, Mukesh Ambani, has moved into his new home in Mumbai which is 27 stories high and worth £630 million (more than $1 billion). Ambani, his wife and three children have moved into the building which is named Antilia, after a mythical Island. It contains a health club with a gym and dance studio, at least one studio, a ballroom, guestrooms and a range of lounges and a 50 seater cinema. There is even an elevated garden with ceiling space to accommodate small trees. The roof has three helicopter pads and there is also underground parking for 160 cars, which will come in handy for guests at Ambani's forthcoming housewarming party.
