Asia's richest man Mukesh Ambani and his wife Nita Ambani moved to their current residence, Antilia, in 2011.
But where did they live before moving into their 27-story tower located in the heart of one of Mumbai's most expensive neighborhoods?
According to Yahoo, the billionaire and his family shared their home with his younger brother, Anil Ambani, with whom he had a public fight after the death of their father Dhirubhai Ambani in 2002.
The Reliance empire was divided in half.
Over the past 22 years, while Mukesh has become one of the richest people in the world, Anil's wealth has decreased considerably, taking him from billionaire to millionaire.
The two brothers lived together in the Ambanis' building, called Sea Wind, with their mother Kokilaben, who still lives there.
Unlike Antilia, Sea Wind is a more modest, 19-storey tall building on Cuffe Parade on the southern edge of Mumbai.
It's not entirely clear when the Ambanis moved here, but Sea Wind was the Ambanis' residence for quite some time.
It has none of the features of Mukesh Ambani and his family's new ultra-modern home, but it is a considerably large place.
Each member of the family had a sprawling apartment to themselves, including the children, but it pales in comparison to the luxurious Antilia. There are no high-speed elevators, no snowflake rooms, and certainly not enough garage space for 168 cars.
Today, Anil Ambani and his family live in Sea Wind. It is also where Kokilaben decided to stay and move to Antilia.
