"The 'green movement' has swept the world and architecture is at the forefront of the new industrial revolution - buildings being by far the biggest energy-sappers in the world. Many contemporary architects are limited by the confines of budgets, time tables and constricting clients. Some industrious innovators, however, are breaking convention and collaborating to launch our imaginations into the future of green design. A surprising number of the following projects are even slated to be built.

From floating eco-cities to sustainable skyscraper farms, modular folding origamic architecture to gigantic green super-spires, here are 24 future green designs that boggle the mind."
