Treehouses bring out the child in all of us. Serving as private retreats, guest houses, or play spaces for family and friends, these enchanting arboreal constructions lift our spirits, inspire our dreams, and offer the promise of freedom from adult worries. In this magical volume, Pete Nelson, a leading authority on treehouse design and the author of three previous books on the subject that have sold more than 200,000 copies, takes us on a fascinating around-the-world journey to discover how treehouses are designed, built, and enjoyed in a wide variety of cultures. More than 35 treehouses are shown in 250 beautiful color images, from locations in China, Japan, New Zealand, Australia, the United States, Italy, Germany, Poland, the United Kingdom, France, and elsewhere, all photographed especially for this book. Nelson, whose frequent appearances on Oprah and Good Morning America and in newspaper and magazine features have helped to spur the soaring popularity of the treehouse, also describes in detail the process of creating--for "kids" both young and old--a fun, safe, and environmentally responsible sanctuary in a tree.
