I have enjoyed watching the earth berm projects going on at this site. I hope to do something similar in the next few years. One thing I have noticed is that there isn't much NEW info on the internet about using the earth in a building project. In my effort to find what IS out there, I have set up google alerts for both "earth berm" and "earth shelter". Yesterday I got a link to a set of videos (which I haven't finished watching yet) but was anxious to share here. The builder, Adam Bearup, is very personable and entertaining to watch. Adam's specialty is ICF and SIPS. He just happens to be in my backyard and could be the perfect consultant WHEN I get to build mine. I hope you enjoy. :)
