Hello,
I hope my question is in the right section.
In my old building, which is currently undergoing a full renovation, there is a centrally located chimney with three flues.
Later, it will only be used for the living room fireplace and can therefore be reduced to one flue. The chimney sweep has approved this.
For various reasons (floor plan and structural stability), the middle flue will be used on the ground floor. After lengthy discussions with the structural engineer about greatly enlarging a wall opening adjoining the chimney, the first flue will be filled with concrete.
On the upper floor, it would generally be better for the floor plan to have the position of the first fireplace flue again, allowing a slightly wider passage. According to the builder, he has seen chimney flues being offset, meaning not running straight up. The chimney sweep was not very enthusiastic and mumbled something about cleaning and draft performance but did not reject the idea. The stove installer also said that it might theoretically be possible, but he didn’t think it was a very good solution either.
As I said, we are talking about an offset of about 25cm (10 inches). Since I will have the chimney rebuilt on the upper floor anyway, I can determine the angle and so on. Does anyone have experience with this? Does it really make things that complicated?
The white pillar reaching to the ceiling is the chimney. I would prefer to push it into the room and have a wider passage instead.

However, I no longer remember the exact reason. Cleaning was a factor, and apparently the draft performance would be significantly reduced.
