These incredible looking tree houses are called ‘Free Spirit Spheres’ and are designed by Tom Chudleigh, and is an eco-friendly living quarter that was created to co-exist unobtrusively with its forest environment. Wooden spheres are built much like a cedar strip canoe or kayak, suspension points are similar to the chain plate attachments on a sailboat and the stairways hang from a tree much like a sailboats shrouds hang from the mast.

German cooperative baumraum offers fully customizable tree houses made primarily of wood and rope, with clean, modern lines that defy the traditional assumptions about what tree houses should look like. The tree houses above were commissioned by clients in Austria and New York, respectively, and were built to suit the individual sites with the intent of disturbing the surroundings as little as possible.
