As the title says, I own over twenty cabin books. This is by far my favorite design/floorplan book. It has 50+ different designs. The review about it simply being a series of identical designs with "expensive bump outs" and "no use of lofts" apparently didn't look at more than a few designs, nor read the actual text of the book. In the second half, the author addresses adding more floor-space cheaply by using lofts for sleeping areas. There are only a few designs with bump-outs, and if you don't like them, turn the page!
My favorite thing is the way the book is organized, the cabins are arranged in sq/ft. order as you look through the first half of the book, going from just over a hundred feet to almost 1,000 (but most are 600 sq/ft or fewer). Each design gets a floor plan and an elevation (exterior drawing), covering two pages per cabin.
The second half of the book gives excellent overview-level information about green building, energy efficiency, off-the-grid ideas, incorporating garages, RV-concepts, and even a few designs using shipping containers!
There is a great chapter on using modular designed 12' x 12' sections to create a mobile living space, whereby you can truck in your cabin, add to it as you can afford to, and even design your own cabin using 20 or so "modules" that the author pre-designed and included in the book (i.e. 4 bedroom modules, 4 kitchen modules, 4 bathroom modules, living rooms, dining areas, etc.). It's a really fun addition to the book.
This is not a book to go deep into any one subject, but it is an excellent overview for the new reader who wants a LOT of survey-level information on cabin concepts. And the 50 designs rank among my favorites for their creativity and individuality. How many round, half-round, quonset hut or yurt-style cabins have you seen in cabin books lately?
Like I said earlier, best design book I own. Buy this book, you will NOT be disappointed.
