I am very interested in earthen Building, and Cob especially! I live in a cold climate (buffalo, and am looking for land in Maine) so most people keep saying i will need to use straw bale, i would love to hear your thoughts!

Thanks so much for your question. I've varied my answer over the years...I likely would have agreed with the others about 12 years ago. Then I thought a hybrid (strawbale on North side; Fast Cob on the rest) would be best. I still haven't worked with strawbales to build walls, but it seems more expensive in terms of cost and resources than Fast Cob! My experience with cob at -10ºC is that a foot thick wall is too thin. My guess is that 18" walls would work well to both hold the heat and not allow it to transfer right through the wall. If I lived in such a climate, I would probably build a small building with a thin cob wall on the outside and a thicker cob wall on the inside, sandwiching a natural insulator between them. Perhaps perlite? One could even build thick walls and consistently place a think strip of perlite in the last "brick" to mimic what I just dexcribed; this would likely be faster and more consistent. And it would allow both the inside and outside "walls" to be attached, which is important for its monolithic strength, although with 18" walls, you could build as heavy a roof as you possibly could and there would be no issue for structural strength.

Do you know if any natural techniques to do earthen sheltered cob, primarily the waterproofing, this seems to be difficult to tackle from a natural sustainable approach

That is surely one tempting offer, to have a house built and enclosed this year still.

Wow, I haven't been invited to Ontario for a few years now! Thanks so much, Monika!

One barrier for me personally is economic-
