@Blaga Miteva Yes, of course! The only parts that wouldn't align would be my land discovery guides, of course. But the building techniques work very well there too.

@Birdie Marshall Yes, there's definitely been some progress in California with building earthen structures lately. Having good connections can make the difference too. Let me know if you run into any issues, and we can see who might be able to help you there.

@Charlotte Fields I can recommend my engineer: Anthony Dente at Verdant Structural Engineers. They can work nationwide for engineering/architectural work for cob and natural homes.
Tutorial video and architectural drawings
Hello Alex! Is what’s on sale the same tutorial I bought about six weeks ago? I have enjoyed watching it all except I can’t get some of the videos to play. I have a question- can regular architectural house plans be used for CobBauge construction?

Hi Charlotte, Yes, its the same materials as the file you should have. The 2014 and 2019 (older videos) will just need an app to open the .rar files. The instructions are in the file. I can help you if you need further help though. I know that can be confusing at first. Yes, for sure! They'll just need to be modified. For example, the floor plan will need to be modified by widening the walls to 18 to 24 inches for cob (usually).

@Mischa Frijns It's okay to ask it here. Actually, we could start a new post about this topic if you like. Otherwise I can answer it here too. I recommend the rock layer under the concrete even if there is no frost line. Its good for drainage still, and a water break to prevent water wicking toward the foundation. The plastic then goes on top of this to further prevent water wicking up.
