Mumbai builder Lodha Developers is starting work on a 1,476-foot-tall structure that, when complete, will be the tallest residential tower in the world -- and home to the super-rich. The developer says World One will cost around $450 million, but its rooms are already selling for up to $12 million. There's other green involved as well: The sprawling structure will recycle water, collect rain and use solar power.
