Since the terms appear regularly overall here, I’ll also say something in an actually somewhat longer quiet thread:
Misunderstanding each other is often due to "Babylonian confusion of languages," i.e., the use of terms that have different regional meanings:
That the dormer (Gaube) is actually only called that when it is set on the roof surface, thus still having roof surface "under itself," is sometimes not considered in everyday language use. When it continues the facade flush with its front side, it is actually called a "Zwerchhaus" (and with a pointed front, thus its own small ridge orthogonally meeting the roof covering, even more specifically a "Zwerchgiebel").
The classic "dormer" usually sits on an (inner) knee wall, and with that, we come to the second term:
To avoid having "head height zero" at the eaves-side end of the rooms, two related methods can be used. One is to make an inner offset by setting a wall parallel to the eaves back into the room. The intermediate space is called "Abseite," and is sometimes accessible with flaps for crawling as storage space. The wall set in front is called "Drempel."
Sometimes another method is preferred, namely the variation of raising the eaves-side exterior wall (on which typically the foot purlin of each eave side rests) higher instead of the wall set in front. This variant is actually called "Kniestock."
The terms "inner" or "outer Drempel" are less common. Especially because regionally one of the two methods is much more popular than the other, so people skip the distinction. This explains why in some regions the kneewall (Kniestock) is called "Drempel" (and it is not understood why this is confusing to outsiders).
Hopefully, this also makes this question understandable:
If the original poster (OP) had meant an inner Drempel here, that would in fact have been a practical proposal: one could then have executed the Drempel lower in the area of the dormers (i.e., pushed it up almost to the intersection with the roof slope), and the parapet height would thus have returned to a normal level. However, here there is an outer Drempel (Kniestock). Since in this concrete case the roof only begins at 1.15 m (and a classic "dormer" sets even higher), the possible parapet height of windows in these dormers logically rises more or less "up to the chin").
In this respect, the advice is logical – but understanding it requires differentiating the terms, as well as replacing the dormers with Zwerchhäuser (which also allows for floor-to-ceiling windows regardless of the Drempel height).
Unfortunately, not every development plan allows this choice. Then roof windows remain as an option for lighting, but they are not effective in shaping the house because they do not create any roof structure.

The knee wall (Drempel) is only for optical and practical purposes, and the kneewall (Kniestock) contains structural elements? (As far as I think I know that)

Can’t you then plan the rooms where the dormers are supposed to be with or without a Drempel and the others as intended?
