Hello,
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 don’t understand this: especially if it was measured on site, the result should correspond more to the reality than to the plan (???)The staircase fits the stairwell opening (thus the reality), not the plan. The planned staircase apparently never matched the planned stairwell opening, otherwise the metal structure would have ended up suspended in the air.morgenstern schrieb:
Yes, that would be my preferred solution. That’s why I’m asking whether the stairwell opening can be made smaller. As a layperson but with some common sense, I don’t think so, since everything broken up like that doesn’t really carry much load. There’s a reason why they say the staircase comes first and everything else adapts to it.
Or is it possible to work with support beams in the basement that could carry the small extension?

I don’t see the trip hazard either; I’m more concerned about going down the stairs. So you mean 95 instead of 104 cm (37.4 instead of 41 inches)?
I’d say at 95 cm (37.4 inches) you can still push off well against the outer wall if you’re going too fast! :p Otherwise, you have to acknowledge that Kerstin pointed out the narrow section to you. Luckily it’s open, so you can still get furniture upstairs.
A complicated but possible option: widen the window next to the entrance door and install a window seat that opens outward.
From what I can gather here, the stairwell opening was built larger than originally planned. The stair contractor was then instructed to base their work on the actual stairwell opening rather than the plan. Using these measurements, they constructed the staircase, which resulted in the "deviation" at the top—the passage is 10cm (4 inches) narrower—and also the overhang against the wall. To achieve a flush fit with the wall, the supporting surface is likely simply missing. The stair contractor is probably not at fault here, as the issue stems from the incorrectly executed stairwell opening. Whether this can still be "fixed" would have to be determined by the stair contractor. It depends on whether it is possible to adjust the support at the bottom so the staircase can be slid further into the stairwell opening. However, the point of contact would be the general contractor, since the stair contractor likely followed the given measurements, even if not the original plan.

Now you even say – although your photos don't really support this – that the element AND its opening actually fit together after all, so where exactly is the problem? Could it be that the stairwell opening is 11cm (4.3 inches) too far "forward"?

Are you fond of joking with us?I really enjoy joking ;-) but I think this is probably just a misunderstanding. What I mean is: The staircase fits the stair opening. That is true in the sense that nothing is hanging in mid-air, you can walk on the stairs, and there is nowhere to fall through a gap.
However, I also say that the distance to the wall is not right. Whether this is due to the stair opening or the staircase construction, I do not know.
If it’s the stair opening, then the planning is incorrect.
If it’s the staircase itself, then I wouldn’t know how it could have been designed differently. This doesn’t mean much, as I have no expertise in staircase construction.
Maybe the metal framework does not need to rest on the ceiling below, but can be fixed in another way. I don’t know.

I am not a staircase builder either, but the structure can definitely be realized with several connection options – this is similar to garage doors, which have different ordering dimensions depending on whether they are installed behind or inside the reveal, while the rough opening size remains the same. Sometimes a bit of miscommunication is enough to result in the finished part needing to be installed “the other way around.” What exactly is the issue for you: needing to pass a bit more narrowly at the bottom (meaning you unfortunately can’t place some decorative clutter in the way) or always having to do the last step at the top like the butler in “Dinner for One”?
