In Treehouse Masters, Pete Nelson designs private escapes for those with a passion to reconnect with nature. Designing multi-bedroom dream tree houses complete with functional plumbing and electricity to simple, one-room lofts, Pete goes out on a limb to create breathtaking realities for a host of clientele. However, creating these homes doesn't come easy. Pete and his team of designers and carpenters, including son Charlie, must endure Mother Nature's shifty antics, dangerous construction equipment and dizzy heights in order to build these sanctuaries.
