Made out of solid cedars, the tree house in Tulsa is composed of three levels. It is fitted for full-sized adults and also includes a 30-foot zip-line complete with a landing deck.
"You know I've been doing this since I was 12 years old; I've been doing it for about 15 years," said Josh Keeley, who built the tree house. "It's taken all of my framing experience and trim carpentry experience to come up with it."
It took Keeley about one month to complete the tree house and he thinks he might have the biggest tree house in the city.
However, it is nowhere near as big as the world's largest tree house, which stands 10-stories tall in Tennessee.
