The curved wall – part 1

Probably the most challenging wall of the whole project was the curved wall that went around the main oak tree. Figuring out how to make this was a process, especially with the gabling and curved helical section on the top part – which never really did get figured out. Spent some time with trigonometry calculations, which was fun but ended up being useless - probably needed to work with 3D helical sections... For the bottom I ended up cutting two copies of a circular arc out of ¾” plywood, put them together, and that was the bottom plate… as you see in the photo. For the top, well... approximating stud to stud, shaving down some 2x4's here and there... it came together in the end ;) Hey, the roof's pretty light!
