Since the publication of Treehouses of the World, the community of treehouse builders has grown tremendously, and many more innovative treehouses have been built around the world. In New Treehouses of the World, world-renowned treehouse designer and builder Pete Nelson takes readers on an exciting, international tour of more than 35 new treehouses that reveal how treehouses are designed, constructed, and appreciated in a wide array of cultures and settings. Both beautifully photographed and thoughtfully written by Pete Nelson, New Treehouses of the World documents Nelson's travels, discoveries, and epiphanies, and explores the ever-growing new frontier of arboreal architecture. The message that Nelson promotes is simple: As sustainable living issues stand poised to become the most important challenges facing the post-millenial age, the positive power and goodwill that a simple treehouse engenders is of greater importance than ever before.
