Man Spent 15 Years Building a Massive 5-Story Tree House
Anyone who ever wanted to have a small tree house in their backyard will be totally amazed by this massive construction, The World's Biggest Tree House, located in Crossville, Tennessee. Designed by Minister Horace Burgess, the structure relies on six oak trees as the base to support all five stories, which collectively stand 97-feet-high. According to Burgess, his inspiration to build the tree house originated from a vision he had in 1993.
