Hello!
I am currently planning my floor layout.
If I draw a straight staircase from the ground floor to the first floor, the ceiling can extend slightly over the staircase. In other words, there would be an "overhang" of the ceiling above the stairs.
My question is, how large can this overhang be? The staircase length I am considering is 4.0 meters (13 feet).
I have attached a drawing for better understanding.
Is a 0.5 meter (20 inches) overhang acceptable, or is that too much?

Do you mean how many risers are under the ceiling, where the ceiling isn’t cut out for the staircase?
In your drawing, there would be 18 risers (each 15.83cm (6.23 inches) high based on a floor-to-ceiling height of 285cm (112.2 inches)). In your example, the steps below the overlap would cause a headroom loss of 79.17cm (31.15 inches), which is probably too much. If this kind of overlap is feasible at all, it only works when climbing a single story — otherwise, the staircases in the upper floor plans would be displaced.
Where exactly do you see only 0.5m (1.64 feet) of overlap?
Without a landing step, I see more like 5.33m (17.49 feet) stair run rather than 4m (13.12 feet).

Hello 11ant.
The attached image is just an example and not to scale. The number of steps is also incorrect; as I said, it’s only an example to illustrate my question.
“You mean how many steps are below the ceiling, where the ceiling is not cut out for the staircase?”
Yes, exactly! For a straight staircase about 4 meters (13 feet) long, is 0.5 meters (20 inches) okay?

What floor-to-ceiling height are we talking about here?I am currently still at the beginning of the floor plan design. I am simply assuming a "standard" floor-to-ceiling height of about 2.6 m (8.5 feet).
What do you mean by a steep ladder? According to the picture (which I found here in the forum), a straight staircase is about 4 m (13 feet) long:
