Talk about staying “green”, this is one of the coolest things I have come across.

I found this titled as “the ultimate tree house” on TechEBlog and this is a quick summation of this brilliant idea:

 Mitchell Joachim, Javier Arbona, and environmental engineer Lara Greden have designed the ultimate treehouse, which “will grow from a few seedlings into a two-story, water-recycling, energy-efficient abode.” Video overview after the jump.

More info and a video:

Despite its odd exterior, the house will look normal on the inside. The walls, packed with clay and plastered over, will keep out the rain, and modern technology will be welcome. Yet there are still a few practical kinks to work out. Joachim wonders, for example, how a planning board will react to a house that constantly expands. Each house will take at least five years to grow, depending on the climate, but Joachim envisions the structures being grown and tended to on a farm.
