Located in Cumberland County, Tenn. (not too far from the HGTV headquarters), stands the world’s largest treehouse. Minister Horace Burgess, the builder of this sky-high marvel, has been working on the treehouse for years and says he plans to continue his work until God no longer provides material for building. This amazing work of art is supported by 6 white oak trees, and at 97 feet, it stands taller than the Tower of London. Covered in porches and boasting a sanctuary and even a choir loft, this treehouse would undoubtedly be an amazing sight to see. Road trip, anyone?
