Final floor plan draft - except for the windows

How about your clear room height?

Where exactly, or how do you come to that conclusion in this context?

From memory, don’t hold me to it:
KG 2.25 - 2.30
EG 2.55 - 2.58
OG approx. 2.45

Best regards!

Because I found them very low in the drawings and also very low on the upper floor. Or is everything already set in stone there?

The ground floor is a few centimeters higher because the last row of bricks was not cut, the basement and upper floor should be as shown in the drawing.

I don't find the heights low at first, let's see how it will be later when the thick floor structure is in place...

The house is already built :)

Oh sorry:x
All the better that it pleases :)
