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 37,000-square meter home, which took seven years to build, is bigger than the Palace of Versailles, London’s Telegraph reported.
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.
From the top floors of the 173m high property are spectacular views of Mumbai and of the Arabian Sea
According to Forbes magazine, Ambani is the fourth richest man in the world, with his net worth at a whopping $29 billion.
He runs Reliance Industries, the oil, retail and biotechnology conglomerate that is the largest private sector enterprise in India.
