When is it not a treehouse?
If any of the following apply, The Treehouse Guide would not consider the structure to be a treehouse; 1. When the house is fully ground supported, even if the tree passes through parts of the structure. There is no interaction with the tree – this is a playhouse. 2. When the tree support is not structurally critical (ie, the structure would stand even if the tree was removed). 3. When the structure has no roof (it is then a tree platform or tree fort if walled).
