Anyone seen this?

Hi Tom,   Quickly looked at the link you posted. A free online book titled: Handbook for building homes of earth. Looks like an informative read with all the basics needed to get started with the most common types of building with earth. I have bookmarked it to look at further on a rainy day. Thank you for pointing it out.
