Here’s a better idea… it came to me last night. Framing this tiny house like a normal house doesn’t work well because the corners and bay windows don’t use the wood efficiently and fill the wall cavities with 2x4s and not insulation.
But If I were to build panels and then screw them together, using the plywood as part of the structure, I think I could have a better insulated structure that would be just as strong. I think I have it all figured out in my head and will get those ideas into drawings today and tonight. Here’s an exploded view and the revised plan so you can see what I’m thinking.
Updated! Here is an updated drawing with more detail.
