the POOP house

In the Architect's (Andrew Maynard Architecture) words...

"No matter which way you look at it, building a house is never green. It takes vast quantities of materials with high levels of embodied energy and water and it creates a lot of waste. Even houses constructed from recycled materials often have an incredibly high embodied energy to implement. So we at Andrew Maynard Architects asked ourselves "what's the greenest building" and we concluded that the answer was "no building at all". But rather than be nihilistic about it we decided that a house should build itself through a lengthy period of assembling house hold waste. Through adopting similar structural logic employed at Stanford University the Poop house is a water structure that, over time, takes all household bio-waste, including human excrement and food, and slowly constructs the walls and roof.

Sounds fantastic in principle... but the ‘yuk factor’ is hard to overcome ... a bit like drinking recycled sewage - no scientific or health reason for it not being ok, just yuk.
