ᐅ What degree of deviation is acceptable when laying masonry?

We visited the kitchen installer today and then went to the construction site where the ground floor was completed this week. We noticed that the kitchen measurements differ slightly from the original plan. According to the plan, the kitchen should be 2.995 meters wide, but I measured 2.909 meters along the wall and about one centimeter more at the transition to the dining area.

I understand that masonry work isn’t exact to the millimeter ("the bricklayer is happy as long as he stays on the property..."), but around 8 centimeters seems a bit much to me. Is this still acceptable, and what would be the best way to handle this? Should I ask the general contractor to have the bricklayers on the upper floor re-measure more carefully? In principle, I could live with a kitchen width that’s about one handbreadth smaller.

Small update. My suspicion was confirmed. The structural calculation for the upper floor was a bit too optimistic in the original plan, and after recalculation, the wall between the bedrooms had to become load-bearing. As a result, the doors no longer fit, which affected the hallway and stairwell. And apparently, I was not informed about this...

There is a saying in construction:

The carpenter works down to the millimeter, the joiner works to the centimeter, and the bricklayer is just glad if the plot of land is correct.

By the way, there are also 50 cm (20 inch) wide base cabinets :p

I was at our shell construction site just a week ago – almost everything fits within 1mm or is perfectly exact. Except for one wall length – that is 3mm too long. My construction manager says the shell builder is allowed tolerances up to 1cm (0.4 inch). Anything beyond that has to be reworked (good luck with that).

Your example shows me again why I didn’t go with a general contractor. It’s such a frustrating black box.

But why 40cm (16 inches) anyway – that can’t be right?

I think it is even more, depending on the length of the wall.

I still need to clarify why they are planning 40cm (16 inches) blocks for me when apparently they don’t exist.

There are even 40cm (16 inches) ones. Saving those 10cm (4 inches) shouldn’t really be an issue. Currently, we have a 100cm (39 inches) cabinet in the middle. We’ll just reduce it to a 90cm (35 inches) one. But I’d really prefer to avoid the stress of the house not fitting together.

I'm not sure, but maybe they do exist in Austria after all.
