If solar power and recycled building materials just aren´t green enough for you, the brains behind the Fab Tree Hab might have the perfect pad. Architects Mitchell Joachim and Javier Arbona, along with environmental engineer Lara Greden, have designed a house that will grow from a few seedlings into a two-story, water-recycling, energy-efficient abode. The Fab Tree Hab,
a mix of ancient and ultramodern technology, isn´t
merely environmentally friendly. It is the environment.
