One step further down the alternative building road, and just a bit more of a stretch for those of you stuck in the square blocks of "modern" civilization, lies Cob Homes. Take a look at these videos to see the amazing creativity, beauty, and yes, crazy, hippy-inspired design, of Cob Homes.
Cob is a mix of sand, clay, and straw.
I truly think this building method has amazing potential for many reasons. Take a look. Please look past the clutter - it seems that the people who live in these homes either are rather messy or just don't care about showing their mess to the world.
The second video shows a Cob-Straw Bale Hybrid.
