Treehouse Masters

Pete Nelson and his crew trek to the Blue Ridge Mountains to build a treehouse for carpenter Mike Reynolds. Perched 16 feet up, it will be the perfect rustic guesthouse to host an Appalachian Christmas tradition.

Pete embarks on a vacation to the pine forests of Scandinavia, stopping first at the magical TreeTop Hotel in Norway. He then heads to Sweden and swims in a frozen lake, before checking in at the renowned Treehotel.

Pete and his crew build a treehouse for the For-Mar Nature Preserve just outside of Flint, Michigan, that aims to be a beacon of positivity in a community still reeling from the 2014 water crisis.

In NY's Catskill Mountains, Pete builds a glass house in the sky by piecing together his clients' collection of 50 vintage windows. The end result is an elegant treehouse completely encased in walls of glass.

Pete heads to Charlotte, NC, to create an owl-inspired treehouse library. The crew constructs a one-of-a-kind masterpiece using rounded walls, curving bookcases, and kid-friendly designs.

Pete surprises two lucky winners by repairing and renovating their existing treehouses from top to bottom.
