With a clear room height of 275 cm = approx. 305 cm floor height
Yes, that was what was mentioned – however, in the text; the drawing seems to be at a different stage. The 15 marked risers at 18.9 (/26) would result in a floor height of 283.5 cm. From my perspective, this step cross-section is at the borderline of comfort. Almost like a row house, thus not really suitable for a single-flight straight staircase.
First there is the plan, later the builders decide that they want a higher ceiling than the standard 2.50. It's just two rows of bricks with costs in the low four-figure range. Planner of the BUs messed up the adjustment of the stairs. How good it is that there is the forum :)
