A full-time staff of 600 maintains the residence, reportedly the most expensive home in the world.
The building is named after the mythical Atlantic island of Antillia. Antillia, according to Aristotle, was a huge island in the Atlantic Ocean known to the Carthaginians.
The Antilia building is situated on an ocean-facing 4,532 square metres (48,780 sq ft) plot at Altamount Road, Cumballa Hill, South Mumbai, where land prices are upward of US$10,000 per square metre.
In August 2008, Altamount Road was the 10th most expensive street in the world at US$25,000/sq m (US$2,336 per sq foot).
Antilia was designed by Chicago based architects, Perkins & Will. The Australia-based construction company Leighton Holdings began constructing it.
The home has 27 floors with extra-high ceilings (other buildings of equivalent height may have as many as 60 floors).
The home was also designed to survive an 8-richter scale earthquake.
