The Treehouse Guys travel to picturesque Half Moon Bay on the California coast to build a beautiful modern treehouse. Spoiled for choices, the guys are surrounded by majestic redwoods, cedar and oak trees, with a river running through the property to boot! With their mad build skills and inventive designs, the guys take this 300 square foot, nearly 20 feet off the ground, treetop get-away to a whole new level.
