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.

So this is the structural shell without plaster, and then built right next to it? I would ask the construction manager if that is really possible. I’m curious about the answer as well.

At least that explains 5 cm (2 inches). With the future exterior plaster thickness, the full 9 cm (3.5 inches). And then the interior plaster on top of that as well…

You should have questioned the even numbers 😉

I don’t know if the room behind is larger.

The room behind will be larger unless the problem lies in the exterior walls. That means the guaranteed floor area and living space will be achieved, just distributed differently among the rooms. There’s no way around that...

Who designs a kitchen at 2.995 m (9 feet 10 inches)? I better not ask.

Hopefully no one, because the dimensions in the plans are always calculated without plaster.

40cm (16 inches) should probably be 36.5cm (14.5 inches) plus 2 times 2cm (0.8 inches) of plaster.
The structural builder thinks, hmm 40cm (16 inches)? Those should probably be 42.5cm (17 inches) blocks...

Although I doubt that because the bricks are 2.5cm (1 inch) thicker than in the plan. I want to go there again tomorrow and measure everything.

Since the builder is acting as the main contractor, hopefully that won’t happen.

He probably meant that kitchens should not be planned smaller than 3.20 meters (10 feet 6 inches) or larger than 2.40 meters (7 feet 10 inches) 😉
