It took 11 years to finish the world’s largest tree house.

In rural Tennessee, built without a blueprint, the structure is eight stories high and spans seven trees. There are over 40 rooms and a chapel that also serves as basketball court. 

KCRW tells the story of Horace Burgess, the man who built the tree house, and what it cost him. 

"I don’t know if I’ll ever be known for anything else. This kind of overshadowed everything else I did in my life," Burgess tells KCRW
