For real dude im feeling the same thing! First off im sure you have done tons of research on alternative housing just like me, tiny houses, earth bag, earth ships. Or maybe your rich and have no money problems idk lol. Anyways broke or not i gotta say check out landwatch.com, CHEAP land on there bro, Im really feeling the cob to but like you i will be doing it alone well with my gf but just us. To me it seems like you should build a tiny cabin for 2-3gs then work on the cob home, since you would be able to put the cabin together within a few months. Thats what im thinking of, and as far as well and a septic tank.... luxiers to some one like me the well would come way first though in my book. i would use composting toliets or maybe you could build a river thing under your house that comes and moves your waste like they did in roam, thad be cool! For water id get some were close to a lake and by a burkey water filter + boiling and catch rain water in a storage tank. Really excited to here back from you.
