How much deviation is acceptable when masonry is done?

You are already at 180cm + buffer.

However, a relatively large free space is created, resulting in long distances when cooking and working. With about 3 meters rounded, you have 1.80 in the middle with a U or II, so 60 cm surplus.

the owed basic and living area will be reached, just distributed differently across the rooms

I fear the external dimensions of the house are correct, and thus several square meters of living space may be missing :oops:

Well, it always depends on the case. Sample calculation: 299cm - 2 x 2cm plaster = 295cm 295cm - 92cm side by side refrigerator = 203cm Side by side refrigerators should have 10cm of space on the sides: 203 - 2 x 10cm = 183cm You're already at 180cm + buffer. So I wouldn't generalize with today's kitchens... Even without the side buffers, you'd be at 200cm = 2 * 60 + 1 * 80

It's well known that "can't" doesn't exist. I definitely wouldn't install the refrigerator with 92cm against the wall.

I was on the construction site earlier and measured the house. The north side doesn't quite fit. The kitchen is missing 8cm, but the staircase is 14cm wider and the bathroom + [Technik] area is 13cm too short, so overall -5cm. The wall between the bathroom and [Technik] is still missing but is correctly marked. Adding this up, one might think that perhaps the structural engineer changed the plans and this was not communicated. The filigree ceilings were definitely made according to the masons' plans since the ceiling was already poured yesterday.

The open-plan room fits overall, except for deviations of 2.5cm each.

Well, at least that. But overall, still a strong package of deviations.

Yes, I will clarify that with the general contractor. Changing load-bearing walls is no longer realistic. What is especially important to me now is to know according to which plan the bricklayers will continue next week on the upper floor.
