Minister Horace Burgess' Treehouse in Cumberland County, Tennessee, rrises 97 feet into the sky, the help given by a live, 80-foot-tall white oak 12 feet in measurement at its base. Six different trees bolster the fortification made of reused bits of timber from carports, stockpiling sheds and outbuildings. The tree house has 10 stories, averaging nine to 11 feet in tallness by Burgess' retribution. He gauges it to be around 8-10,000 square feet. He surmises he has sunk about $12,000 into the task.
