Pete Nelson, the world's best-known treehouse designer and builder, wants to put readers in trees-his motto is, "get `er done, so you can BE in a TREE." His new book is a comprehensive source of inspiration and practical information about treehouse design and construction. To that end, he explains the basics of treehouse construction with his own recent projects as case studies. Using photographs taken especially for this project along with diagrams, he covers the selection and care of trees and the design, style and construction of treehouses. To ignite the imagination, Nelson presents twenty-four previously unpublished treehouses in the United States, Europe, Africa, Asia and Australia.
