Designing Your Natural House (Wiley-Vnr) 
Reviews
Although the authors don't always agree on the specifics of visual aspects, their playful banter reveals that not all their ideas are steadfast rules, and allows you to witness the brainstorming give-and-take between the authors while offering you enough information to make your own decision.
Few complete home designs are displayed, but they are reprinted from the authors' other books (Natural Architecture by Woods, Underground Designs by Wells), and are placed in context of demonstrating a point. Otherwise, pages are filled with illuminating commentary and ideas on specific components of homes, including roof lines, light fixtures, proportions, window types, door placement, siding, and lot layout.
You will not be told how to build a house, but rather you will develop a designer's critical eye and help you to understand why so many modern homes have visual aspects that just don't look "right". (Example: narrow shutters on wide windows -- how will the shutters ever cover the window space if they are not proportional?...you'd be surprised how often I see this faux pas in local posh neighborhoods).
A helpful bibliography points to other books to fill out your home design repertoir.
(Wells is the grandfather of earth-sheltered/underground architecture and still offers design services from Cape Cod. You can write to him (via snail mail) and he'll kindly reply.)
Whilst not getting into the nuts & bolts of building, innovative ideas are shared page after page.
Humour and how-not-to examples effectively tackle the otherwise so-subjective topic of aesthetics.
An entertaining coffee-table book for wanna-be home builders and a good reference for teams bogged down by discussions of good taste in architecture.
