Hello, we are currently planning a house with a gable roof (38°) and are unsure about the ceiling height for the ground floor. The standard offered by our builder is a structural height of 262.5 cm (103.5 inches) / clear ceiling height of 246 cm (97 inches). The floor-to-ceiling windows are 226 cm (89 inches) tall. Now we are considering raising the ground floor by either 12.5 cm (5 inches) or 25 cm (10 inches). However, we also have a relatively high knee wall of 150 cm (59 inches) (possibly 137.5 cm (54 inches) might be an option or make more sense).
Here are the questions:
1) Will the eave height become too high overall with the increased room height and the high knee wall? On the long side, we have no windows on the upper floor (currently no strip windows either), so it will be a large closed area. Is there a way to visually break that up?
2) Do the windows need to be raised as well, or are 226 cm (89 inches) still suitable?
Additional info: Our living room (including dining and kitchen) is quite large (about 11.5 x 4 meters (38 x 13 feet)), so we are concerned that a low ceiling might feel oppressive, hence the idea of raising it.
Perhaps someone has experience with these ceiling heights and can offer some advice.
Thank you!

Now I actually measured the living/dining/kitchen area of my apartment. The clear ceiling height is 260 cm (102 inches), and the window recesses end at approximately 245 cm (96 inches). Since we don’t have shutters or anything like that (which I’m glad about—I don’t like shutters because they always look like a fortress).

That can be the case, but doesn’t have to be. Often you need to refer to sectional drawings because floor plans don’t specify what the measurements refer to.
For roller shutter boxes, a height of about 30 cm (12 inches) is commonly used when they are delivered integrated with the window. A distance of around 30 to 40 cm (12 to 16 inches) from the ceiling is a good guideline if you don’t want the windows to appear pushed up too high or the ceiling to visually drop.
In any case, I recommend always adjusting room height and window height together. Increasing the room height by about 20 cm (8 inches) — and it doesn’t have to be in 12.5-cm (5-inch) increments — while keeping the window height standard would produce the described effect of casting a shadow on the way to the ceiling.The 226 cm (89 inches) is the rough opening height, according to the sectional drawing.
We definitely want roller shutters, so we need to include the 30 cm (12 inches) for those.
If I take the rough room height as 275 cm (108 inches) minus 30 cm (12 inches) for the roller shutters, that leaves a maximum rough opening height of 245 cm (96 inches) for the windows.
What about lintels — are they necessary for certain windows? For example, we have planned a 3-meter (10-foot) wide sliding door... that would reduce the height by a few more centimeters, right?
If not, is my calculation correct that with a rough ceiling height of 275 cm (108 inches), I can have a maximum window rough opening height of 245 cm (96 inches)? (I’d probably choose a bit less anyway, since that’s quite tall.)

We definitely want roller shutters, so we need to account for the 30 cm (12 inches).
If I take the rough structural height of the room as 275 cm (108 inches) – minus 30 cm (12 inches) for the roller shutters = max. 245 cm (96 inches) rough opening height for the window. The section drawing should also show whether the lintel is placed at the top edge of this opening or if the roller shutter box comes first. What I meant refers to roller shutter boxes attached directly to the window unit – but often separate, classic roller shutter boxes are installed (and in that case, the window size is indicated in the drawing).

Otherwise, the ceiling can span freely there – though only up to a certain width. For wide windows or doors, you will need a beam (similar in size to a lintel).

As the client, you should decide what you want for yourself. In my opinion, this is best based on whether you want the windows to be proportionally taller if the room height increases by 20 cm (8 inches), or if you prefer to have about 60 cm (24 inches) of "upper wall" space below the ceiling instead, regardless of what part of that is roller shutter box, lintel, or wall. That is your fundamental decision – leave the professionals to figure out how to implement it.

Additionally, the screed height must be taken into account.
