1. Antilia (Mumbai, India)
Value: N/A. Estimated to be around $1 – 2 billion.
Owner: Mukesh Ambani – net worth: $21.3 billion
No house is more suitable to rank as the leading amongst the most expensive billionaire homes in the world than Ambani’s “humble” abode – the Antilia. This 27-story high mansion is run by a staff of no less than 600 people. With 6 levels just for parking, a health story, and 3 helicopter pads, it is hard to beat the Antilia when it comes to cool features.
