Antilia is named after a mythical island in the Atlantic Ocean.
It is a 27-storey building but since some ceilings are double-height, it's closer to the size of a 40-storey building as it is 570 feet high.
It houses 600 staff members that help maintain the mansion. There's an entourage room where security/body guards and other assistants can relax.
The Ambani home is equipped with a health spa, a salon, a ballroom, 3 swimming pools, yoga and dance studios.
There is a private theater than can seat 50 people and on the roof of the theater is a terrace garden.
Six floors in the building are strictly dedicated to parking with a space for 168 cars.
The tower alone has 9 elevators. There are separate elevators for guests and the Ambani family members.
Two design motifs - the sun and the lotus - are repeated throughout the mansion in rare materials like crystal, marble, and pearls.
The mansion has 3 helipads on the roof.
