THIS IS THE BOOK TO OWN IF YOU WANT TO TALK INTELLIGENTLY TO YOUR BUILDER AND KNOW WHAT TO LOOK FOR DURING CONSTRUCTION! It will tell you EVERYTHING! I started out with a builder that was planning to be shady and knowing stuff in this book scared him off. I knew too much for him to cut important corners. I asked specific questions and he fled. My current builder and I have good relations and we can intelligently talk specifics of the trade because of this book.
