I'm friends with a guy with a startup called RamRock that's focused on compression-formed masonry. He says if the soil has enough clay, you can drop dirt into his machine on one end and get bricks out the other that are ready to use. (If there's not enough clay you can add some special goo that does the same thing.) So you can dig out a basement and then use that dirt to build the house over it.
I'm also friends with the guy who runs the Hexayurt Project. Different approach, but same goal.
This is not in our normal area of discussion but I'm finding this design
by Abeer Seikaly to be absolutely brilliant. It might be a metaphor forConscious living and reaching out to those in need...
