Largest Tree House in the World

Monday, 26 November 2012

This stunning threehouse can be found in Cumberland County, Tennessee. It's 97 feet high and it's built on a 80-foot-long white oak. The treehouse has 10 floors and its size is about 8,000 to 10,000 square feet. It took 258,000 nails and $12,000 for a 56-year old landscape architect Horace Burgess to build it.
