No, the walls within the yellow area are certainly not load-bearing. In this house, the load-bearing is in the thick masonry walls.
How do you know? I've spoken to several different people but received different answers.J justusandersson said:
It was masonry, plaster, and 70x180 planks in the middle, chicken wire, etc.
Some say it may have become load-bearing over time if other walls have been demolished, or it could have been added to "reinforce" and therefore isn't on the drawings.
According to the drawings, it's not load-bearing though. I don't want to risk the neighbor's floor above settling.. What should I do? Demolish or not?
The original drawing shows that your apartment was once a locale of some sort, maybe a store, with two rooms and no kitchen. Exit toward the street, in a window section. The toilet was an outhouse in the courtyard. The locale was later converted into an apartment, with the inner room divided into a kitchen, entrance, and closets/pantry. It's some of these later walls that you're in the process of demolishing. They are not original, but perhaps (wild guess) still up to 100 years old. They do not have a load-bearing function.
