ᐅ Is it possible to slightly offset load-bearing walls between the ground floor and the upper floor?

berny23Hello,
in general, load-bearing walls should ideally be aligned vertically to avoid additional costs for beams, lintels, or similar structural elements. Of course, everything is possible—it’s always a matter of effort and cost.
Now to the specific question:
If there is a load-bearing 24 cm (9.5 inches) solid masonry wall on both the ground floor and the upper floor, is it permissible for the upper floor wall to be offset by 12 cm (5 inches) without requiring additional support measures? It should be possible because the walls still overlap by 12 cm (5 inches), so the load should still be adequately transferred, right?
What are the limits for such an offset, assuming it is at all feasible? Could even a larger offset be possible? This would allow for a bit more flexibility in the floor plan.
Perhaps someone has experience with this.

The load-bearing wall on the upper floor doesn’t just rest on the ceiling of the ground floor and the supporting wall beneath it with its own weight, but also carries the weight of the upper floor’s ceiling.
Imagine a pair of scissors, a scale, and a seesaw—these concepts will clarify the principles involved here. From my perspective, your intended design would create a case of a "misguided load transfer."
If the floor plan dimensions are so tightly fitted that you cannot simply make one room on one floor slightly wider to align the wall exactly above or below it on the other floor, I would say the floor plan designer has not fully completed their work.
Catching up on structural engineering tasks after the planning stage is often possible but significantly more complex and costly. If money (and steel, and aesthetics, and headroom due to beams) are not a concern, it is theoretically possible to offset load-bearing walls by half a bay in a staggered pattern.
