India (Mumbai)

The largest, tallest and most expensive private house in the world is Antilia, a 27-storey personal skyscraper and home of Indian businessman Mukesh Ambani in Mumbai. Designed by American architects Perkins & Will and completed in 2010, Antilia has a total living floor area of 37,000 m² (400,000 ft²), plus 168 parking spaces, three helipads, several swimming pools, a health spa and theatre. It occupies a 4,532-square-metre (48,780-ft²) plot on Mumbai's exclusive Altamount Road, and accommodates 600 staff. Measuring 173 m (568 ft) high, the generous triple-height spacing of the 27 floors mean that the building is actually as tall as a typical 60-storey office tower.
