We all need a place to call home.

Obviously some folks ‘need’ a more impressive one than others. Sometimes its hard to define ‘excess’ and other times… well…

India’s richest man, and Forbes’s fourth richest man, Mukesh Ambani, has built the world’s most expensive house in Mumbai. It is estimated to be worth $1 billion.

The lavish building– named Antilia, after the mythical island– has 27 stories, is 173 meters high and has 37,000 square meters of floor space — more than the Palace of Versailles. It contains a health club with a gym and dance studio, at least one swimming pool, a ballroom, guestrooms, a variety of lounges and a 50-seater cinema. There are three helicopter pads on the roof and a car park for 160 vehicles on the ground floors. It’s obviously quite a job keeping all this running smoothly, so the house, if you can call it that, also boasts a staff of 600. And all this for just Ambani, his wife and their three children to enjoy.
