We have heard the expression, go big or go home. But here we have a combination of both as we look inside the most expensive house in the world. Officially known as Antilla, this is the family home of Reliance Industries Chairman Mukesh Ambani, which has around 600 homes and is located on the prestigious Altamount Road, Cumballa Hill.
A staff of 600 is employed to maintain the residence 24/7. As of November 2014, it was officially deemed to be the most expensive private residential property in the world, valued at $1 billion.
