This 27-story, 40,000 sq/ft tower, pictured above, where no two floors are identical, is the unique and extravagant creation of owners Mukesh and Nita Ambani. Costing greater than a hotel or high-rise, due to its custom measurements and fittings, it comes down complete with a six-story carpark and also begins on the ninth floor.
570 feet in height and mostly glass, it has a staff of 600 servants. The ballroom boasts a crystal chandelier ceiling and features retractable showcases for artwork and entertainment stages. It has an indoor/outdoor bar, green rooms along with a nearby “entourage room” for security guards and assistants to relax. Each floor is double the amount average height, technically which makes it 60 stories tall, perfect for its helipad. This home dwarfs any other, financially and in stature, and will probably be number one for some time.
