The estimated worth of the cantilever building is approximately Rs 15,000 crore.
Chicago-based Perkins & Will and Santa Monica-headquartered Hirsch Bedner Associates were hired by Ambani to design and build Antilia.
Antilia boasts of 3 rooftop helipads, a 6-floor car parking, a 50-seat movie theatre and 3 floors of Babylon-inspired hanging gardens.
Media reports say maintenance work at Antilia requires an expenditure of Rs 2.5 crore a month.
