A well designed book with nice photography, but as another reviewer mentions, the title is a misnomer. These are high-end, architecturally-designed buildings, made with big money. The introduction mentions Frank Lloyd Wright's cabins, so that should give you an idea of the genre of these buildings -- cabins for millionaires.
The author writes about cabins reconnecting people with nature, but most of these buildings would be an interference to that end: getting back to nature is not about smothering yourself in luxury. Some of the descriptions are informative, others are a bit fluffy. She quotes Gary Snyder, but these buildings don't walk his talk, not by a long shot.
