12" woodchip/clay enclosure outside of frame?

I am looking for information or better yet real life examples of either woodchip/clay or light straw/clay wall enclosure systems which are built outside of the frame as in stress skin panel installations. The problem of course is the width of foundation needed to support frame point loads as well as sill/ joist loads as on my current drawings and, the 12" outside wall system @ approx. 1000lb/cu. yd.. Real life examples seem to be absent. Obviously, cement and form costs could reach prohibitive proportion. The home is to be built in southern ME. I am an owner/builder. Thanks
