This book was really fun to read. The pictures were beautiful and the surrounding of most of the homes were incredible. Some times the floor plans were a bit confusing and one of them had no definitions for the numbers that represented the rooms. It definately inspired me to do more with less and to consider green building as my next project. I was a bit dissapointed in the definitions of some of the energy saving apparatuses. I wish that the book would have gone into more detail on the excerpts of geothermal, solar hot water, PV arrays, and wind turbines. At best these were teasers and left me wanting much more explaination. I will say it gave me a world of great ideas. I would be very interested in a book on totally off the grid, fully functional with flushing toilets etc incorporating all aspects of rain water collection, grey water heating and collection, optimal design to do this and more, plus sub 1200 square feet homes that offer options on what can be afforded. In depth explainations on all the buzz words like living machines what it entails (cost,size,optimal location, size vs. amount processed per hr or day or what? better diagrams with flow directions and larger in format etc. This should give the author another book to write that I for sure will purchase. I am well over 13!
