1Appalachian Christmas Treehouse
Pete and his merry men trek to the Blue Ridge Mountains to build a treehouse for one of their own: carpenter Mike Reynolds. Sitting 16 feet high, it will be the perfect rustic guesthouse to host friends and family.
2International: Scandinavia
Pete journeys to the pine-forested splendor of Scandinavia to explore Norway's magical TreeTop Hotel and Sweden's floating Treehotel, with tree homes suspended by cables and accessed only by retractable ladders.
3Nature's Super HQ
Pete and NTS build a tree house for the For-Mar Nature Preserve just outside Flint, Mich.; the 5-platform nature headquarters serves as a positive addition to a community still reeling from the water crisis that began in 2014.
4Glasshouse Treehouse
Pete treks to New York's Catskill Mountains to build his first glass house in the sky; piecing materials together like a puzzle, Pete uses his clients' collection of 50 vintage windows to construct an elegant tree house encased by walls of glass.
5The Owl Treehouse
Pete pushes his design skills to create an owl-inspired tree house library in Charlotte, N.C.; evoking the face of the bird and using all sorts of curves, including rounded walls and semi-circle bookcases, the crew builds a one-of-a-kind masterpiece.
6Surprise Makeover Edition
Pete surprises two lucky winners to receive complete, top-to-bottom, $20,000 renovations of their existing tree houses, giving old, rundown childhood structures much needed repairs, remodels and complete makeovers.
