I hope I have considered all necessary details.
And now you want a finished draft? The development plan allows a lot, and you give the forum too much freedom. It is common for the builder to visualize their ideas and present them to the forum so that proper criticism can be made and improvement suggestions can be given. Here are parts of your text translated pictorially:

In addition, we want to do without a full 2nd upper floor
Why?
“gibt vor” and “maximal zulässig” contradict each other
Now you are being very picky. "Maximal" is correct.
But here then this, yes with dormers, but it reads as if lower is also permitted, then without dormers:
In the development plan there are different areas where other roof shapes and pitches are also permitted. The first details relate to the building plot, the later details to the entire development plan. For the building plot a gable roof with a minimum roof pitch of 30° applies, so dormers are allowed here.
