Latest to go into our forthcoming book Builders of the Pacific Coast. Wood spheres are made of two laminations of wood strips over laminated wood frames. The outside is then finished and covered with clear fiberglass.
The "Spherical Tree House" concept borrows heavily from sailboat construction and rigging practice. It’s a marriage of tree house and sailboat technology. Wooden spheres are built much like a cedar strip canoe or kayak. Suspension points are similar to the chain plate attachments on a sailboat. Stairways hang from a tree much like a sailboats shrouds hang from the mast.
