The Treehouse Guys are joining forces with longtime friend and treehouse builder Michael Murphy for his latest project in Linden, Virginia. They're building a treehouse for a family of climbers, Susan Leopold and her kids on their 300-acre wooded property near the Appalachian Trail. With a passion for plants, Susan hopes to share her ethno-botany background with friends and family in a tree-top apothecary. Perched in a poplar tree and two red oaks, this two-story tree-pothecary will be the perfect haven for nature lovers near and far.
