I've been working with the cob slipform method (using forms to shape and construct cob walls) since about 2020. I would definitely have a hard time going back to hand-sculpting cob walls. Unless I was only interested in getting that more organic, uneven look to my walls. But in this video, I explain more of why I won't be hand-sculpting cob walls anymore. The new method is so much better in almost all aspects.

Wattle & Daub is an earth building technique that's not often talked about these days. It's basically a thin cob wall built between post & beam and woven lattice. I don't normally recommend wattle & daub for exterior walls unless you live in a tropical climate. The walls are too thin for substantial insulation or thermal mass. But they're quick to build and work great for natural, non-toxic interior walls in any home or building.

Greenhouses with insulated north and northeast/northwest walls work great. Does anyone with considerable natural building experience have their two cents on light straw Clay being a suitable insulation for such an application? I’m wondering how it will handle the moisture in the winter time.

Let's start a discussion about foundations for your natural buildings. Constructing the foundations is very important, and it's one of the things I'm most passionate about when it comes to building structures. Please leave your questions here and let's talk about this critical component of building.

I've started a project! I'm still looking for suitable and affordable land for my cob home so in the meantime I'm getting familiar with some natural building materials. I live in an old house, built around 1890 with multiple additions. My west wall isn't well insulated and my kitchen pipes freeze every winter (I'm in central IL,USA). My plan is to tear out the entire kitchen wall, pack the space between studs with slip-straw, and finish with an earthen plaster. I'm starting with a small section as a learning lab. Yesterday was demo which I finished today, and started my first foray into slip-straw. Lessons on day 1: I definitely need to round the handle of my pounder. Even though I sanded the edges and corners, my hands are still feeling it. Slip-straw has a bounciness I didn't expect. I hope I compacted it enough. We'll see tomorrow. I'm starting to understand slow, yet immensely enjoyable building. Heart and soul are ingredients you don't see on any materials list. I have read differing opinions on how quickly you can remove the forms. Some say let it dry at least overnight, some say you can remove it right away and keep building the next level. I wonder when you keep working right away if the base put. Anyone have experience in that?
