there's a strong Neverland-vibe about this..! holy. god.: "'The Minister’s Treehouse' in Crossville, Tennessee is 100ft structure built by minister Horace Burgess from the early 1990s through 2004. The entire building wraps around a giant tree and was built completely without blueprints, sprawling to an estimated 10,000 square feet inside, including a four-story swing set."
