Hello, good evening!
I would like to thank all active members and moderators here once again, as I have already received some good advice just by quietly reading along. However, we are currently struggling with questions that cannot, at least for me, be clarified on the internet.
Here is the situation:
Planning a single-family house with very tight specifications
Maximum house footprint: 121m² (1300 ft²)
One story
Lower Saxony
We would like to have a dormer on one side and narrow windows in the knee wall on the other side, if possible. Unfortunately, we have encountered conflicting information from architects, so I would like to ask the following questions:
Which parameters are taken into account when calculating the upper floor, in order to make the best possible use of the knee wall height?
The Lower Saxony building code states that a full floor requires a clear height of at least 2.20m (7.2 ft) over two-thirds of the floor area.
I also know that the external thickness of the gable wall is not included in the calculation.
Are there other factors that should be considered to maximize the upper floor area, such as stair openings, interior walls, or similar?
From what knee wall height or under which conditions are narrow windows on the roof slope side allowed on the upper floor, or are they impossible in a single-story building?
If you need any additional information about our project, please let me know!
Sorry for my non-expert terminology!
Good luck
Tom

Floor-to-ceiling? Where did I write that?
You can install the row of windows higher than 30 cm (12 inches), for example 60 cm (24 inches), with windows 70 cm (28 inches) high, lintel... This fits a knee wall height of 160 cm (63 inches).
You plan the terrace with gravel surface or a permeable finish. The roof overhang must be less than 50 cm (20 inches).
I know that a gallery, meaning an opening in the upper floor slab, reduces the living area, but that would make no sense, since this area would then be subtracted from your upper living space anyway.
But actually, every architect should know by which legal means the number of stories is kept.

I just interpreted it that way!
For the terrace, I’m also planning to use gravel!
Architects are a tricky matter! Some say one thing, others say something else!
That’s why I asked again about the problem here!
If I have a dormer on one side, it’s going to be very tight with a knee wall height of 1.60m (5 feet 3 inches), probably not feasible. That’s why I’m asking about peak wind speeds!

Try to increase a potentially lower knee wall by installing built-in cupboards. Simply add sliding doors in front, with shelves and clothes rails behind them; this way, the lower slope visually disappears without any real loss of quality.

The extremely high knee wall is important to me only because of the windows! That’s why I’m pushing it to the limit!
Since your job title in the second part also relates to this field, at least as an employee, you are probably familiar with this area and can surely interpret it!
Will you tell me your LK in Ni?

I don't think any terrace will be rejected – but alright. Our house has a footprint of 131 m² (1410 sq ft) and we have 190 m² (2045 sq ft) of living space – so your 121 m² (1303 sq ft) should be enough for 150-160 m² (1615-1720 sq ft) living area as well.
We don’t have dormers... with dormers and no tricks on the ground floor, a knee wall height of about 1.2 m (4 feet) is more realistic – maybe 1.3 m (4.3 feet).
What kind of "architects" do you have? Find one who actually charges a fee; they will definitely know the details and take responsibility.

Will you tell me your advanced course in Ni? Uh, what does it say for me? I’m in the north, the far north
