Classic question... Is the wall load-bearing/does it have a stiffening function?
Functionalist house built in vertical timber from 1936. Two floors above a basement with the same floor plan.
The current wall is circled in yellow. On the red-marked wall, the intermediate floor and the floor toward the attic rest.
Classic hip roof. What makes me unsure is that the roof structure has a post down in each corner, a bit into the house, resting on a beam that crosses the floor to distribute the weight. However, the span in the opposite room is somewhat longer without extra walls.
