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.

Thank you for your responses
I found in the documents that the staircase was planned with 18.4 / 29.8. I assume this means the rise of the stair treads should be 18.4cm (7.2 inches) when covered.
This would mean that, according to the plan, I would need to compensate for 6cm (2.4 inches) height at the bottom step. That can’t be correct...

nordanney4 Aug 2020 12:48We also had significant differences in floor heights. This is quite common with formed stairs (regardless of any defects). The screed installer usually adjusts this quickly—at least that's what I know—unless the tiler uses a lot of adhesive.

hampshire4 Aug 2020 14:57This is not good workmanship. Ask how it is supposed to be finished – if it is meant to stay like this, it is a defect.
Formwork cast concrete stairs always vary slightly in height. They are rarely ready for finishes.
The "first step" with 12cm (5 inches) is not really a step yet, as the floor buildup is still missing.
The following steps vary within a range of 3cm (1 inch), which the tile installer will adjust.
The 24cm (9.5 inches) step at the top should be checked again to see exactly what happened there.
