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.

That is not wrong,

For the floor area ratio, it is incorrect; for everything else, at least misleading.

Where the federal states, as far as I know, agree is on a 2.3 m (7.5 ft) story height

There is no consensus. For example, Bavaria and Brandenburg have removed the definition of a full story from their state building codes (it now only appears in transitional provisions), while North Rhine-Westphalia has switched from story height to clear ceiling height (currently not legally applicable due to a moratorium).

Where can I read about this? In the development plan?

If your concern is not whether to buy the plot or not, but how to get as close as possible to your dream home, you should discuss the details with your designer. Many regulations affecting roof design may still be hidden in the development plan.
