Build a Cob House For $58K Instead of Paying $400K For a Mortgage
The average American paying off a $200,000 house will hand over $343,000 by the time they actually own it. $143,000 just vanishes into interest payments. But there's a proven alternative that eliminates debt entirely: building a cob house with your own hands. In this video, I break down the REAL numbers behind debt-free natural building and show you exactly how regular people on normal incomes are opting out of the mortgage system.

This was an amazing video. The breakdown was very eye-opening. Please consider uploading this to YouTube. More people need this awareness and these options. There's so much turmoil in the world, I believe this will give a lot of people hope and tons of options.

Hi Alex, is it possible to incorporate the Earthship cooling tubes into the design of these cob structures? I'm thinking that it may eliminate the need for the installation of A/C. Any thoughts on this?

@Alex Sumerall Yes, exactly those ones. I would try to make them look more esthetic though. I was also wondering if those same cooling tubes could be inserted into the floors just like heating/cooling vents from a conventional furnace. This could possibly take away the bulky look from them being installed into the walls. Just thinking out loud.

How to Build a Footer-Stemwall Foundation (New Video)
I just uploaded the new video documenting how to build a footer-stemwall foundation. This is one of my favorite styles of foundations for any sort of building. It's especially great for heavy, load-bearing earth walls! This video also presents the project that all of our workshop students will be participating with this year! Join me here to get hands-on experience building these massive cob walls: https://www.thiscobhouse.com/cob-workshops/ Leave your questions and comments below so we can discuss this style of foundation.

Just saw your video, Alex. I've always wondered about foundations and how it is done so the building doesn't collapse. That was a ton of hard work, but very cool and answered my questions. Thanks so much!

@Em Nat Hello Em Nat, all of the details of the 4 types of foundations are covered in his comprehensive class.
One of my online students built this Cob House!
I've actually never shared these before, but one of my online students from a few years ago built her own beautiful cob house in Sri Lanka. She did an amazing job! What do you think?

I've been interested in natural building since the early 1990s. I'm looking forward to learning more so that I can one day build my own home.
