A US grandfather initially planned to build a $150,000 treehouse for his grandchildren’s summer fun, but the project expanded into an elaborate $325,000 custom complex complete with a pirate ship and 200-foot zipline. Featuring high-quality materials and professional engineering to ensure safety and longevity, the structure includes multiple levels, architectural details like live-edge cedar siding, and various adventurous elements designed for play and enjoyment.
