Owned by the chairman of Reliance Industries, this home is valued at about about $2 billion. It is 27 stories and over 400,000 sq. feet. Built among the slums of Mumbai, it has a theatre, heli-pad, 2 health floors, guest rooms, 6 stories for parking, quarters for the 600 staff - all for a family of six, who live on the top 6 floors. A little ostentatious, don’t you think.
