Hello. I'm planning on building a small cottage this summer in Southern Oregon. I'd love if I could have 200 interior square feet and a loft done by November. I'm looking into both earthbag and cob. Cob is SO much more charming, but I'm intrigued by the earthbag because it is so much faster. I've read a book on each, but haven't found a whole lot of info on how they can be used together. Does anyone have any ideas on hybridizing the two to get the charm of cob with the speed of earthbag? Can you, for example, leave large spaces for windows between earthbags and cob them in for desired funky shapes rather than using the standard square/arch shapes that they make earthbag windows with? I can't start until July and I have to work at least part time as well. Any other ideas on how this can get done in one summer and still be gnometastic? Thanks!

Cob makes a good plaster over the earthbags, and can be sculpted around doors, windows, etc. to get that funky charm. You may need to use something to "key" the cob to the bags.
