Your gray boxes make it more difficult to read. The top one even removes all text underneath/behind the box. The left box states that both the outer wall and inner wall are load-bearing. In the lower right box, it says the load-bearing inner wall is like stair enclosure, i.e., the text above. If I had to guess, I would say that the "rear" inner wall, which separates the kitchen, is load-bearing since it is shown in the cross-section, and I think I can read the living room in the section about the floor structure, i.e., that some form of beam is described there. But these are pure guesses.
