When Buddy Melvin set out to build a treehouse in 1997, he only planned for one room. Today the sprawling structure has 16, including bars, bedrooms, a pool room, and a dance floor. At the heart of the treehouse is an enormous trunk, which continues to grow, fed by the subterranean stream below. Buddy’s treehouse has a few broken floorboards and crooked beams, but he likes it that way. Used as a gathering space for dance parties and motorcycle groups, the treehouse is home to many happy memories.
