When Treehouse Guy Michael found out his younger brother Tom and his buddy Scott had bought an amazing piece of land in the Columbia Gorge National Scenic Area in Washington, he couldn't wait to convince them to let the Treehouse Guys work their magic. Built atop a single majestic Douglas fir, the 350-square-foot treehouse proves to be quite the engineering feat with its unique octagonal shape supported by a compression ring and cables. And since they're working in Bigfoot country, the builders are on watch for Sasquatch as they race to finish the treehouse for their special clients.
