We're about halfway through the Winter Sale and I wanted to share something important. **59 spots remaining** (at the $50 price). The most common mistake I see in natural building? People skip proper foundation work. Bad foundation work can lead to severe and expensive problems like: walls cracking, uneven sinking of walls, and moisture intrusion (the leading cause of building failure). All from improper foundations. Cost to fix: $5,000-$50,000. Or worse - starting over. Here's the problem: Most natural building workshops don't teach foundations. **But this course STARTS with foundations:** - When to use concrete slabs vs. rubble trench vs. stone - Proper drainage design - Moisture barriers - Frost protection - Foundation work for ALL climates This section alone is worth more than the $50 sale price. And it applies whether you're building cob, straw-clay, rammed earth, adobe, strawbale, hempcrete, or conventional building. **59 spots left.** Sale ends December 31st, midnight.

I was thinking of doing the dual wall method. 18 inches of cob 6 inches of straw clay or hempcrete. I think the best way to do it would be to build the wall up as one, but I worry about the insulating wall getting rained on. Would it be smart to use slip forms to build the 18 inch cob walls and put ties in it, build the roof, then go back and put the forms back on the wall at 24 inches to fill in the 6 inches of insulating materials using the ties to integrate the walls together. Or, would you have a better suggestion?
