This company offers 50 small cabin plans, available on a CD. I have no idea what the plans are like, but I like the rendering here, allowing a novice builder to visualize the construction. (This is what we did with 5 tiny home plans in Shelter in 1973.)
This website is loaded, and the CD sounds like a pretty good deal, but I haven’t seen it. I ordered the free download of a sample and if it’s any good, we’ll add these guys to our Tiny Homes List of links on our website.
