People who know and work with Pete Nelson describe him as a tree whisperer. For his part, Nelson lets the trees do the talking. He's a world-renowned treehouse designer and builder, and this series documents the work he and his team of craftsmen -- including his son Charlie -- do to create incredible homes and businesses in nature's canopy. Pete uses a combination of science and art to realize clients' sky-high aspirations of magnificent multibedroom treehouses with elaborate kitchens and bathrooms, or simpler, peaceful one-room escapes. Other backyard escapes featured in the series include a spa retreat, a brewery, and a honeymoon suite. ``We awaken that inner child who dreams of living among the trees,'' Pete says. Treehouse designer Pete Nelson and his team turn clients' sky-high dreams into incredible realities. Pete tackles the first climb-in movie theater; concessions are served to seating pods through a pulley system and loungers elevate into the trees to give perfect views of the big screen; a tree house for monkeys at the Los Angeles Zoo. A friend of Pete's has the treehouse bug and decides to open a treehouse B&B; the classic A-Frame structure will have all the amenities and a waterfall that pours from the wraparound deck to the pond below. Pete answers the call of duty to build a tree house in Pennsylvania that focuses on the children of Marines; cargo netting off the deck provides an exciting way to enter, while even more nets inside form a bridge to access a private loft space.
