ANTILIA - WORLD'S MOST EXPENSIVE RESIDENTIAL PROPERTY

Antilia is a private home in South Mumbai, India. It is owned by Mukesh Ambani, chairman of Reliance Industries and has a staff of 600 to maintain the residence 24 hours a day.

Antilia is the world’s most expensive home, costing approximately $2 billion to construct.
The home has 27 floors with extra-high ceilings. (Other buildings of equivalent height may have as many as 60 floors). It is considered by some to be the tallest single-family house in the world. Because it includes space for a staff of 600, others reserve that honor for a house meant to be occupied only by a single family.

As of November 2014, it is deemed to be the world's most expensive residential property, after Buckingham Palace, which is designated as a crown property. It is thus the world's most expensive private residential property, valued over $1 billion.
