Treehouse Masters

Pete takes on his first international project in breathtaking Norway. Teaming up with a local builder, he creates a one-of-a-kind retreat that sleeps eight and offers stunning views of a nearby lake.

In Texas Hill Country, Pete and the gang build a rustic double-decker hideout that features a saloon-style lower level with a glass floor.

The team heads to New Jersey to build a luxurious, Adirondack-style campers' retreat for an outdoor-loving couple. Glamping features include a screened-in porch, a floating barbecue deck and a cozy hanging bed.

Pete comes to western Washington to create a 20-foot high treehouse built for action. Thrills include a 55-foot-long bouncy-bridge entryway and a zip line through the surrounding forest.

Pete builds a barn-like birdhouse retreat on a Wisconsin couple's 100-acre farm. Separate pods include an art studio, an office and a lounge, plus a screened-in porch overlooking their stable of alpacas.

Pete travels to Alaska to build a mountaineering lodge in the shadow of North America's highest peak, constructing an A-frame masterpiece with breathtaking views of Denali for the Mt. McKinley Princess Wilderness Lodge.

Pete takes us on a tour of this unique treehouse with three separate pods -- art studio, office and lounge -- that make this barn-like, birdhouse-inspired treehouse the perfect play land for two retirees.
