Two sisters in Farmington, PA ask Pete to build a "bear" observation treehouse on their 1000-acre property. Pete creates his first ever mid-century decagon treehouse with walls of glass windows and even a "bear cam" tracking system.

A family in Independence, OH who run a hope center want to build a therapeutic space in the trees. Believing in the healing power of trees and treehouses, Pete builds a butterfly-themed treehouse in a cluster of 6 trees featuring a climbing net and loft.

An arborist in Humboldt County, CA pushes the team's skills to the limit, requesting a tri-level residence a dizzying 60-feet up in 3 giant redwood trees! Pete and the crew take the comforts of home to new heights in this bohemian chic treehouse.
