Hello everyone,
As our new build is slowly nearing completion, today we measured the stair treads for the flooring on the half-turn staircase from the ground floor to the upper floor. Unfortunately, this was the first time we measured them. We noticed the following:
First step is 12cm (5 inches) high
The following steps range between 17cm (7 inches) and 20cm (8 inches) high
The top landing step is 24cm (9.5 inches) high
We would like to use tiles as the flooring… but this is proving difficult because so much height needs to be evened out, and the individual steps vary significantly from each other…
Is this still within standard regulations, or does this indicate a construction defect?
The building specification states the following:
The staircase between floors is to be constructed as a concrete staircase. The stair flooring is to be installed by the owner.

Formed concrete stairs always vary slightly in height. They are rarely ready for covering.
The “first step” at 12cm (5 inches) is not really a step because the floor build-up is still missing.
The other steps vary within a range of 3cm (1.2 inches), which the tiler will compensate for.
The top step at 24cm (9.5 inches) would need to be checked again to see exactly what happened there. Why is the first step not considered a step?
The screed is already in place, so it should be a normal step. Or did I misunderstand you?
I have also spoken to a tiler who could level it out, but I will still bring it up with the builder first to find out what their intention was. Especially because the first step and the landing create a few extra centimeters that will need to be leveled...

The "first step" of 12cm (5 inches) isn’t really a step at all, since the floor build-up is still missing.
The other steps vary by about 3cm (1 inch); the tiler will compensate for that.
The 24cm (9.5 inches) at the top needs to be checked again to see exactly what happened there. I would almost bet that the 6cm (2.5 inches) surplus at the top is missing at the bottom on the first step.
The screed is probably already in place ... and the floor covering is missing everywhere, whether at the bottom, on the stairs, or at the top.
Therefore, on average, all steps should ideally match the targeted 18.4cm (7.25 inches) riser height of the staircase design.

The screed is already done, Hello
That’s right, the screed is in place.
This means the entire staircase needs to be rebuilt by a screed installer.
That will be the most cost-effective and sensible solution.
The costs should be covered by the person responsible for botching the staircase.

I would agree that any excess at the top results in a shortage at the bottom. Most likely, an incorrect height measurement was taken somewhere, so the staircase basically ends up 6cm (2.4 inches) too low. The discrepancies between the other steps shouldn’t be there either, but those might still be fixable.
The same thing happened to my best friend with his structural builder: the staircase to the attic was mistakenly cast using the measurements for the staircase to the basement. However, the builder corrected this, and because they have a very good relationship, both parties took it “in good humor.” If he had wanted, the builder would have even torn the staircase out again!
