ᐅ Corner wall/plaster around entrance door

Hello,
my front door was installed last week, and afterwards the joint was plastered.

As you can see, the angle of the wall here is not 90 degrees, not even close (it clearly slants inward). This only occurs here, not at any other window or opening. Does anyone know if there is a standard for this? The builder believes this is normal and cannot be changed, since you never know the exact width of the door anyway. According to them, this is acceptable, etc.

On the other hand, I have seen several houses where this is not the case...
It looks the same from the outside...

Of course, the construction contract does not specify such details...

Thanks for the help. Regards,
Philipp

Hello,

For this, there is the DIN18202 standard for plastering work. It specifies the deviation from a right angle as a so-called "stichmaß" (measured gap). This refers to the gap between the wall and the right angle relative to the corresponding length. Of course, this can also be checked with a spirit level.

This can be corrected, but it is actually quite labor-intensive. Is it a property developer or a general contractor?

Best regards,
Jann

I consider this completely normal. It is the same way with us, by the way.
