research on how best to build a treehouse without doing much damage to the tree. We asked our kids their input on what they wanted most, and took it into consideration (sadly, electricity was not included. :) It took us about two months, working mainly on the weekends. The treehouse is accessed through a trapdoor through the deck which you climb up through the ladder. Overall, it was a smashing success! My boys play in it every day, even in the rain.
