For someone who hasn't done much research outside of watching some Tiny house shows, I found it had some useful information. I was mostly interested in technical details and building cost, so the other chapters about pets, relationships, etc. weren't as interesting to me, though they are certainly important. In that regard, my favorite chapters were 2 (Planning: Research), 4 (Building: The Unspoken Realities of Doing it Yourself, Plus The Cost), 5 (Why We Chose Our Design Aesethetic and Layout), 9 (The Rewards, Benefits, and Challenges of Downsizing). The afterword had a good list of resources as well.
They talked about being on the Tiny House Nation TV show a little too much, as I wasn't really interested. I did find it interesting the degree to which the TV shows can lie about the cost.
"These shows are great for entertainment and design ideas, but not for true actual cost. Take it from us, we were on one of these TV shows and they stated the full cost of our house was in reality just half of what the materials alone cost."
The book could have done with a more thorough editing review process as well.
