I am building a single-family house with a general contractor.
After the screed was laid, it was noticed that the staircase is offset by 10cm (4 inches). That means it starts 10cm too early.
According to the plan, there should be 1.05m (41 inches) of space in front of the stairs, but currently, there are only 94cm (37 inches).
As a result, the last step at the top is 10cm (4 inches) lower than planned (according to the plan, the last step was not supposed to be a full step).
The staircase is a straight two-stringer staircase. Since the house has a basement, the staircase cannot simply be shortened because it would otherwise be unsupported.
Are there any options to reduce the stairwell opening? The floor (or basement ceiling) is made of 18cm (7 inches) concrete (prefabricated concrete slab).
Even during planning, the 1.05m (41 inches) space in front of the stairs felt a bit tight; I would be glad to have at least 1 meter (39 inches) here.
Thank you,
morgenstern

I assume we are talking about
? – still, I don’t fully follow your words. At first, it sounds like
as if the stairs start closer to the exterior wall, but then
it rather seems that the heights don’t match (?)

but rather as if the heights were incorrect (?)The heights are correct. By "10cm deeper," I meant a 10cm (4 inches) larger tread width. So "deep" in terms of depth, not height.

But there’s probably very little you can change there. (Unless you tear it out and do it once again, properly).

I’ll try to give a brief summary again—sorry if I explained it too complicatedly.
The plan was for a staircase where the top step would be only half the usual tread depth (about 15cm (6 inches) instead of 29cm (11.5 inches)). However, it was built with almost the full tread depth, so the staircase extends 10cm (4 inches) too far into the hallway at the bottom.
The staircase builder adapted to the existing conditions because the stair opening had already been planned 10cm (4 inches) too large. The staircase design never matched the planned stair opening.
To fix this, the stair opening would have to be reduced by 10cm (4 inches), the metal substructure removed, shortened, and then reinstalled.
