Hello there Permies. I'm new to the boards and this is my first post/question. I'm from Southeast Pa. I'm still very new to the idea of Cob and am still reading The Cob Builders Handbook and The Hand-Sculpted House. I want to build as my first project a very tiny, roundish potting shed. Eventually, I want to build my own tiny house. First off, I just want to say I've been reading around on the subject on this forum and it seems like its gotten away from being simple and gone towards being so technical. Don't get me wrong, I understand the structures have to stay up. It's just that my mind set is on what people used to do a long time ago and what people do in 3rd world countries where they don't have all the resources that a lot of people on here recommend. I'm willing to work hard but I want to keep it simple. Anyway, on to questions about my plan....The shed on the inside will be 4' x 4' x 6' tall. Since it's so small how deep do I have to make the rubble trench foundation? Whats the thinnest I can make my walls? The roof will be held up by some old 2x4s I have laying around. Here's a picture of my dirt test jar from the only place I have to dig on my property. It looks to me that I don't have enough clay. What do you think? I would love to see some pics of any tiny sheds that people have done on here if you want to shoot me an email. Thanks so much!
