The specs
Antilia, dubbed the "mansion in the sky" by the Times, was built in consultation with US architecture firms Perkins and Will and Hirsch Bedner Associates. Its construction was reportedly influenced by Vaastu, an ancient Indian belief similarly to the Chinese's Feng Shui. Each level is twice as high as a normal floor.
