The Greene family of Asheville, North Carolina, owns a jewelry store and a historic Victorian home called "The Carolina Jewel." Now they're looking to add another jewel to their collection with the help of The Treehouse Guys: a giant getaway in the trees. The treehouse, affectionately named "The Diamond in the Sky," is nestled in the heart of the Blue Ridge Mountains and features an old moonshine element to celebrate the local history. This massive treehouse proves to be the largest the guys have taken on to date.
