I would love a treehouse. I like watching the tv show where a guy designs big ones. I don’t need a big one unless we decide to live full time in one now that the kids are full grown. I would like that. In a forest where there are lots of big trees and away from a city. I would like one that has several rooms to walk to and not just one room. One to have a bedroom, bathroom, kitchen, family room, and extra rooms for the kids to stay in. Just big enough for the activity not enormous. I think rooms have gotten too big, waste of space. Slides and swings would be good for us and the grandkids. Lots of activity to keep us moving.
