Feel silly-unable to put the picture like others
Anyway, as seen in the photo, there is a long gap about 110mm between the side of the internal stair and the frames. if it is 10mm, I would think the gypoc would block it, but this 110mm is too much.
There is another 70mm gaps in another place
I would think either the frames too small or the foundation too big.
Is there a standard of the acceptable error?
