I’m not sure if this is the right section, but I’ll just post my question here:
What percentage deviation from the planned values should be expected or accepted?
Example: A room is supposed to be 350 cm (11 ft 6 in) wide according to the plan, but it is only 335 cm (11 ft). Would this still be within the tolerance range where nothing can be done?

I’m not sure about the exact legal standards, but that is a huge difference. Everywhere we measured precisely, the masons worked with about 0.5 cm (0.2 inches) accuracy… so it is definitely achievable if they want to. Therefore, I can’t imagine that such a large deviation would still be considered acceptable.
I didn’t measure every wall in our home, but in the areas where we did, the deviation was generally less than 4mm (0.16 inches), with the largest deviation found being around 6mm (0.24 inches). With the deviations mentioned by the original poster, I would primarily be concerned that the walls might also be out of plumb.
Vicky Pedia14 Jan 2020 08:52The allowable tolerances in structural construction are regulated by DIN 18202. Table 1 deals with shell construction tolerances. In your case, a deviation of 16 mm (0.6 inches) is permissible. Now, it should be discussed whether a demolition is proportionate and why the error was not detected during the initial setup.

An insider once told me about a large car service center that always adds 100–300 milliliters (3–10 fluid ounces) less oil than specified, depending on the vehicle. With premium oil costing around 30 euros per liter (about $3.50 per quart), this adds up to several thousand euros per year.
Just trouble!
