Hello, I'm thinking about building a round house with a large glass section and wondering about its structural integrity. A total of 13m long glass section, measured on the outside of the curved wall. No interior walls along this part. On top of this, a low-sloping shed roof, about a 6-degree slope. Principle sketch attached. I generally think that the round shape will help stabilize everything, but anyway...

- 3m high posts at the front on which the beams rest. Can construction timber handle this or is glulam necessary? I assume buckling is mainly the problem and the question is how much the window frames resist.. Swedish Wood always recommends glulam posts 90x90 in their calculation program for shed roofs, which feels wrong.
- Let's say the above is okay, i.e., 3m high posts in construction timber. Can I attach the windows to these posts or will there be problems? I'm mainly referring to the curved shape of the wall, which makes the posts non-parallel: the gap between the window frame and the post becomes about 1.8 mm larger on the outside of the window than the inside. Better to attach the windows edge-to-edge (if possible) and let the posts stand freely outside/inside the windows?
- I'm considering widening the circle in certain places, so that the span increases by 80 cm. I've tried to google the span for two screw-laminated beams (245+120 mm in the example image) but haven't found an answer. Does anyone know the spans for beams that are "laid" on top of each other?
- Any thoughts on problems that might arise? Shear should probably be examined.
