Over the years Kelly and I have built up a great deal of free online content to help those looking for low-cost, sustainable building options. The amount of information has grown so vast that I now refer to these sites as “our family of websites”. If you’re looking for dirt cheap, DIY, sustainable building information then I encourage you to search our sites. You’ll find dozens of free articles, book reviews, videos, Q&A from experts in their field, photo galleries, house plans, and on and on. Enjoy.
