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.

"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
