People need to find better things to do with their time than to rat on their neighbors for a tree house. Melinda Hackett put up the round, cedar tree house for her girls in a tree in her tiny Greenwich Village backyard and her neighbors reported her saying it looked like it was and unsafe and she didn't have a building permit for the tree house. Seriously people, since when did you need a permit for a tree house. It's not like the thing is constructed of 2X4's and is an eye sore. Melinda Hackett spent $5,000 to construct a tree house made of cedar wood for her children. In the end, Melinda was allowed to keep the tree house for her girls and the tree house was granted landmark status, but not after a long battle in court.
