ᐅ Is the staircase dimension too small for a half-turn staircase?

We would like to keep our half-turn concrete staircase from the ground floor to the upper floor narrow to save space in other rooms.
Finished tread width: 94 cm (37 inches)
Tread run: 30 cm (12 inches)
Overall stair opening: 2.18 m (7 ft 2 in) wide, 2 m (6 ft 7 in) deep
At the moment, I only know the clear floor-to-ceiling height on the ground floor: 2.47 m (8 ft 1 in)
The architect suggests that the staircase size is only a makeshift solution and that he would make the stair construction wider.
In other respects, our architect tends to exaggerate (he is an older gentleman).

@nordanney I’m not going to justify myself either. Thank you.For what exactly now? If it’s going to stay that superficial, then I agree with your general contractor. The staircase is a makeshift solution and unsuitable for daily use or annoyingly tight. It’s too narrow by 30cm (12 inches).

The architect now says the stair size is only a last resort and that he would make the stair construction wider. Not really a last resort since it complies with DIN. But it’s not very comfortable to use. I would also prefer to make the stairs more comfortable.

In other areas, our architect tends to exaggerate (older gentleman). This example doesn’t support that conclusion. What does age have to do with it? Rather, it shows more experience.

Please share the plan with all dimensions. A stairwell opening has at least two measurements.
I personally prefer a minimum of 27 cm/18 cm (tread/riser) and 1 m (39 inches) width.

That might be true in this case as well. However, in many aspects, he fits the worst stereotypes. According to the colleagues and experts interviewed, he was often completely wrong with fixed, untrue claims. Therefore, I am currently cautious about his statements, which is why I am asking you all a general question.The superficial remarks are sufficient for my situation. Thank you.
And additionally, do not confuse the story height of 280 cm (110 inches) with your clear room height of 247 cm (97 inches). To your 247 cm (97 inches) the entire suspended ceiling plus floor structure must be added to determine the height that the staircase needs to overcome.
