Pete Nelson and his team put forth superhero efforts to build a treehouse for the For-Mar Nature Preserve just outside of Flint, Michigan. This five-platform "nature headquarters" aims to be a beacon of positivity in a community still reeling from the 2014 water crisis.
Pete pushes his design-skills to create an owl-inspired treehouse library in Charlotte, North Carolina. Evoking the face of the bird and using all sorts of curves, including rounded walls and semi-circle bookcases, the crew constructs a one-of-a-kind masterpiece.
Pete treks to New York's Catskill Mountains to build a glass house in the sky. Piecing materials together like a puzzle, Pete uses his clients' collection of 50 vintage windows to construct an elegant treehouse encased in walls of glass.
In Texas Hill Country, Pete and the gang build a rustic double-decker hideout, set among six live oak trees and featuring a saloon-style lower level with a glass floor.
