Yes but my question is still unanswered.
At some point in the build, finished floor levels must have been discussed, were they not?
Yes I understand you'd asked them to bring floor levels to the same height, and rightly so.
Was this asked for before the doors went in?
Do you have plans, or they winging it?
I'm actually serious.
Finished floor height must be written somewhere.
Even if it's only the height that they leave it at!
What is the height of the door above the boarded floor? I know I've already asked, couldn't tell from your image. Must have something you can use as a reference.
The point I'm trying to get to is that, if they just fitted the doors as they saw fit, and not to any spec or instruction, they're wrong and should be made to change it.
If I just laid a floor with no regard to floor heights and I was too high or low, I'd be responsible for putting it right, simple as.
