I am considering doing a roof lift and thus adding another floor to our summer cottage. Therefore, I have started to look at the current load-bearing construction, which most likely needs to be reinforced.
An idea I want to try here in the forum is that I am thinking about a framework construction that will support the upper floor. The idea is that the framework construction should be built inside the existing wall studs, partly to make the framework visible indoors. Now to my question, is it appropriate to have a load-bearing construction on the floor beams and thus not directly above the existing sill?
Attached is an image that describes the idea itself.

I understand your idea of avoiding drilling into the floor as a shortcut. Principally, I find the solution questionable. The best approach is if the loads from the extension can be transferred directly to the foundation. It might be possible, but it entirely depends on how large the loads will be. There are definite limits to the amount of pressure allowed on the length sides of beams. In a stud wall, the loads are distributed across many studs. With a post construction, they become more concentrated.
