Located in Crossville, Tennessee, the Minister’s house is the world’s biggest tree house, and was built by Horace Burgess. It is 97 foot tall (3om), 10-story high, uses 6 trees as its foundations, and took over 14 years to be built. “I built it for everybody. It’s God’s treehouse. He keeps watch over it,” said Burgess, who got inspired in 1993 after a vision. “I was praying one day, and the Lord said, ‘If you build me a treehouse, I’ll see you never run out of material.” Cost of construction you might ask? $12,000!
