Stairs in the hallway, the floor plan is actually already done :o(

Hello,
we are currently facing the same consideration. We would also like to rotate the staircase and we also have two full floors. Has anyone already implemented this solution and can share some information about it? Maybe someone could send a photo of the entrance area? I find it hard to imagine how it looks at the entrance under the staircase. Unfortunately, I can't find a floor plan or a photo of such a solution online.
Thank you all.

Then just go ahead and post one from your plan here. Only the mini-info

And we would also like to rotate the staircase, and we have two full floors.

still has very little substance for a well-founded discussion. It can still vary a lot what one should imagine in this regard, especially how the room layout in the "surroundings" looks.

I have now also created a new topic with pictures and additional information.
