Staircase with different step heights

I would put that on the staircase builder's list of defects ... there are clear rules and tolerances ... it is also a warranty issue!

yes, according to DIN 18202, 2.5 cm is too much (I would have to check), there are clear specifications in it, furthermore, the finished staircase may only have a rise/rise and tread/tread of +/- 5 mm according to DIN 18065, if the basic staircase already does not fit by 25 mm, it will be difficult to compensate...
