I just finished reading “The $50 and Up Underground House Book.” Mike Oehler is the author and designer of this book and the videos that go with it. We watched those too. I’m 95% sure that this is the type of house we will be building come spring or summer. Anyone thinking about maybe building a natural house of some kind really should read this book. If you are thinking about an underground house, you should definitely read this book. Everything he says really makes sense. He explains the process and the mistakes he has made to get to the process he uses. The how to design a house part was the best though. There is a packet that comes with the video with a printable design kit! I can’t wait to play more with that. I will post that part later. The only thing I wish there was more of in this book is the real basic stuff. He seems to write the book for people who already know how to build a post a beam structure. I don’t so I bought a separate book for that part. It seems like everything will come together fine though. More to share soon!
