A radical new building concept coming out of Asheville, North Carolina, has recently wrapped up. The LEED-Platinum pursing NauHaus project used organic hemp bio-masonry materials with some other cutting-edge green building technologies, such as the new Serious Windows---the house aims to be carbon-neutral. The exterior landscaping of the project will be done using permaculture design principles. More builders and homeowners need to be thinking in this direction--it's the future. You could take it one step further and pursue the Living Building Challenge, that would be awesome, any takers???
