India’s richest man has moved into world’s biggest private residence.

Marking the end of seven years of construction work, India's richest man is planning a housewarming party for his 27-story palatial new home in Mumbai, replete with no fewer than three helipads and an air-traffic control station on its roof.

The 570-foot-tall glass tower, called Antilia, "features a swimming pool, a health club, a salon and a mini-theatre," reports the Times of India. "The first six levels comprise the garage where more than 160 cars can be parked. Atop the parking lot is Antilia's lobby, which has nine elevators." The house also has a garden that can accommodate trees, according to the Telegraph, and a separate ballroom. About 600 staffers will be required to run Antilia, named after the mythical island in the Atlantic.

Mukesh Ambani

The house belongs to Mukesh Ambani, who owns much of the oil and retail giant Reliance Industries. He is estimated to be worth about $27 billion. Experts told the Guardian that "there is no other private property of comparable size and prominence in the world." Ambani, the fourth-richest man in the world, co-ran Reliance with his brother before the two had a falling-out and split the company.
