I told the boys I would build them a tree house. I said it shortly before we knew we were going to move to a new house last year. The new house has only one back yard tree, so this is it.
The one-tree design was supposed to use diagonal corner supports that would lead back to the tree. I wasn’t a good enough woodworker to make this feel sturdy to me, so I opted for legs. I have been referencing a really good treehouse building book. (Amazon link)
Two pairs of perpendicular cross-beams, screwed to the tree, form the main support structure. The plywood floor was a re-use scrounged from a thrown-away mini-golf putting green! I’ve only installed half the floor and none of the railing or roof parts yet.
