ᐅ Single-Story Construction – Is It Possible to Include a Dormer in the Upper Floor?

Hello,
I hope it’s okay that I’m starting a new topic here (I had already opened a similar one, but now it’s getting more specific).
Does anyone have experience with whether it is possible, in terms of dimensions, to install a dormer on the upper floor in a single-story building?
I want to achieve more usable space with vertical walls instead of sloped ones.
The building is located in Schleswig-Holstein, and the building regulations state:
Full stories are above-ground floors that have at least three quarters of their floor area with a height of at least 2.30 m (7 ft 7 in). A top floor set back from at least one exterior wall of the building or a floor with at least one sloped roof surface counts as a full story if at least three quarters of the floor area of the floor below have a height of at least 2.30 m (7 ft 7 in); the height of the floors is measured from the top edge of the floor slab to the top edge of the floor slab of the ceiling above, or for floors with roof surfaces up to the top edge of the roof covering.
The definition is clear, but is this possible with a single-story structure?
Google didn’t help much when searching for “single-story with dormer.” A floor plan would be especially helpful.
Thank you very much.

No, anything between 1.0 and 2.0 m (3.3 and 6.6 ft) is only counted as half.
That is not correct!
The area with a height of 2.30 m (7.5 ft) is what counts.

So, from 1 meter to 2.3 meters (3.3 feet to 7.5 feet), only half is counted.
How is counting done below 1 meter (3.3 feet)?

It is wrong. Forget that! See mine and @Kekse

It is wrong. Forget it! It is not wrong; these are just two different things:
Living area)
The calculation is standardized nationwide. Areas with less than 1 meter (3 feet) room height are not counted at all, between 1 meter and 2 meters (3 ft and 6 ft 6 in) counted half, and only from 2 meters (6 ft 6 in) full.
Definition of a full storey)
This calculation varies depending on the state building regulations. Where the states generally agree, as far as I know, is on the 2.3 meters (7 ft 7 in) storey height concerning which area in the attic counts at all, and 1.4 meters (4 ft 7 in) of average projection above ground regarding whether a basement level is counted. Differences exist in the ratio of this attic area above 2.3 meters (7 ft 7 in) or higher in relation to the floor area of the storey below. One state building code might say two-thirds, and another three-quarters.
And—without having read all sixteen state building codes—I believe that in some cases, partial credit for low-height areas plays a role. Otherwise, why would the question about how much knee wall and/or dormer opening the full storey rule triggers have been discussed here multiple times?
Regarding Schleswig-Holstein, the quote in post #1 says that the state building code there does not take this aspect into account.

Huh? Maybe you should just answer the OP’s question instead of bringing up living area calculations... although the floor-to-ceiling height also depends on the knee wall height, nothing is “halved or calculated in that way” here.
