For years, the towering structure in Crossville, Tennessee, was known as the unofficial largest treehouse in the world. Earlier today, Guinness World Records officials confirmed in an e-mail to The Huffington Post that builder Horace Burgess can replace "unofficial" with "official."
Known as The Minister's Treehouse, Burgess explains the inspiration behind his nearly 10,000-square-foot-structure. "I built it for everybody. It's God's treehouse. He keeps watch over it," Burgess told USA Today in a 2007 interview. "I was praying one day, and the Lord said, 'If you build me a treehouse, I'll see you never run out of material.'"
Burgess started the project in 1993 and has used recycled materials almost exclusively throughout the house. According to the Daily Mail , a whopping 285,000 nails hold everything together, though he's only sunk about $12,000 into the project so far.
In addition to numerous rooms, the house features spiral staircases, trap doors, a choir loft, and on the third floor, a basketball court. Supporting all of that -- all ten stories of house -- are six load-bearing trees and one gigantic 85-foot oak tree, writes the NY Daily News .
