Treehouses

Today in class we critiqued our sketches of trees and treehouse ideas. I am not sure with what I want my treehouse to look like exactly. The most important aspects that I would like are a deck that is either attached all the way around the house or is separate from the house but still connected somehow. Another quality I want to include is going as "green" as I possibly can while planning out how the treehouse will be made. Everyone else had many different creative ideas that have opened my eyes to new ways I might want to design the house.
