In this timeless guide, David and Jeanie Stiles explain basic building procedures through clear, simple instructions and nontechnical line drawings that illustrate every step of the project, from the earliest sketches to the final cedar shingle. The authors outline five basic designs that can be adapted to virtually any set of conditions, and throughout the book they emphasize safety for both adults and children. In addition to line drawings, the book contains a section of full-color photographs highlighting a variety of tree house projects, plus helpful building tips based on interviews with their owners.
