When the Ambani residence is finished next year, it will be the most expensive home in the world: a 27-story skyscraper in downtown Mumbai. The cost? $2 billion!
But the Ambani family can well afford it, because Mukesh Ambani, head of India's petrochemical giant Reliance Industries, is the fifth richest man in the world and is worth $43 billion.
Forbes has the story:
The home will cost more than a hotel or high-rise of similar size because of its custom measurements and fittings: A hotel or condominium has a common layout, replicated on every floor, and uses the same materials throughout the building (such as door handles, floors, lamps and window treatments).
The Ambani home, called Antilla, differs in that no two floors are alike in either plans or materials used. At the request of Nita Ambani, say the designers, if a metal, wood or crystal is part of the ninth-floor design, it shouldn't be used on the eleventh floor, for example. The idea is to blend styles and architectural elements so spaces give the feel of consistency, but without repetition.
Antilla's shape is based on Vaastu, an Indian tradition much like Feng Shui that is said to move energy beneficially through the building by strategically placing materials, rooms and objects.
