Now we have been looking at several new constructions from different manufacturers (and craftsmen!). In two of these (different house models and craftsmen), we have noticed that the interior walls are "wavy" when we look down at the baseboard, i.e., at regular intervals, the interior wall is not flush against the baseboard. There's a difference of several mm, and it's not something you have to look closely to see as it's clearly visible. Without having measured, it looks like the gap could well be spaced 60 cm apart, suggesting that the drywall screwing might be too tight on the interior wall. Or it could be the opposite, that where the drywall is flush, the stud is and where it gaps, the drywall sways inward. Does anyone understand my somewhat vague description? 
We don't feel that this is acceptable in a newly built house put up by craftsmen! Can this be avoided with OSB panels even in the interior walls? Those of you with building experience, what do you say? What is your experience? In hindsight, we should have asked if there is OSB in the interior walls of the houses where we have seen it "waving" against the baseboard.

I agree with you, if they are indeed pros... Eti...
If I understand correctly from your description.
It could be metal studs and they are first screwed together so the screw heads stick out beyond the stud
then the drywall is screwed in place and it "rides" on the screw heads positioned at the studs
then the drywall is screwed into the metal stud in the floor and ceiling and will then curve in between the studs.

The vertical ends of the plasterboards are beveled so that you can fill the joints without creating a "bump" along the seam. Could it possibly be that the painter was careless in filling this indentation all the way down to the floor?
There could be many possible reasons for this. We have shavings behind the gypsum and it's still like that in our house here and there. Don't know if it can be said to be exactly every 60 cm though.
Could also be related to the type of trim? We have very thick and stiff trims, painted on site. If they are thin trims, I assume they are easier to bend slightly a few millimeters towards the wall so that it might appear straight to the eye?
But I agree with you, I also had higher expectations on how it would look. But I find it difficult to judge what one "should expect" and what is due to them not being careful enough when they nailed them, etc.
However, one shouldn't have exaggerated trust in how well things are done just because it's craftsmen (so-called professionals) doing it. That's something I've learned during our journey. They probably don't have the time to be as meticulous as one would be oneself. At least not all of them...

The phenomenon you're describing is something you're close to solving yourself if I understood you correctly. The plasterboard is screwed onto wooden or metal studs with c/c 450mm (sometimes c/c 600mm on exterior walls), which the board then rests against, but on the floor, there's naturally also the sill that the board is against, where you don't screw. And since studs are never perfectly precise, especially with wood, and with metal studs the stud is actually inserted into the sill, which doubles the metal thickness there, the plasterboard will ride on these points. Add to that the joint compound in the seams, which builds up a bit, and you end up with an undulating wall... Whether or not this is acceptable to you is irrelevant to the craftsman, as the contractor’s agreement is with the house supplier, where these tolerances are regulated according to AMA, which allows quite a bit in terms of wall straightness tolerance. Apologies for the text block, but the byggahus forum does not allow me to break lines for some damn reason
