I have been working with several builders and contractors to build my first basement. We live in a locations where no one has a basement and I could not find anyone to help me. I went to a seminar on how to build your own home and someone told me about this book. The writer explains exactly how to build nearly every type of basement. So far I found the book to be a must read for anyone who has a home. Read about what your missing if you don't have one or read about how to add one to your home your living in. I think this book will catch on like wildfire later.
