Built by the world's fourth richest man, Mukesh Ambani to the tune of $1 billion, the gargantuan 27-storey high-rise will be inhabited only by Ambani and his family -- in addition to a corporate facility. Nicknamed "Antilia" after a mythical island, TreeHugger Lloyd also called it one of the dumbest so-called 'green' buildings ever. No wonder too -- despite this behemoth boasting vertical gardens, according to Time the rest of the building is positively excessive: The lavish building... is 173 meters high and has 37,000 square meters of floor space -- more than the Palace of Versailles. It contains a health club with a gym and dance studio, at least one swimming pool, a ballroom, guestrooms, a variety of lounges and a 50-seater cinema. There are three helicopter pads on the roof and a car park for 160 vehicles on the ground floors. It's obviously quite a job keeping all this running smoothly, so the house, if you can call it that, also boasts a staff of 600. And all this for just Ambani, his wife and their three children to enjoy. Though this eyesore takes the cake for a mind-boggling display of senselessness by a record longshot, unfortunately it's not the only one out there.
