Screed - incorrect height - how to fix?

Hello everyone,

now I also need a few opinions on our problem.
We are currently in the middle of building our house, everything has gone smoothly so far.

Last week, the screed (cement screed) was applied. Since yesterday, the screed has been walkable and we were on the construction site again for the first time.
In doing so, we noticed that the heights of the screed in the hallway and the wardrobe do not match.

The plan was for the entrance area/wardrobe to be tiled, but the remaining hallway to have parquet (like the entire rest of the ground floor, except for the bathroom). This was also recorded in the workshop plan.

For the parquet, a covering height of 15 mm was planned, for the tiles 13 mm.
Unfortunately, the screed installer reversed the heights exactly. In the entrance area/wardrobe there is still 15 mm of space (but it should get tiles), in the hallway only 13 mm (but parquet should be laid there).
We of course addressed this directly with the screed installer last night; he has now sent us the plan he received from the site manager, in which tiles are mistakenly marked for wardrobe and hallway, which does not fit at all. He is now referring to this plan.

On Wednesday morning we even went through the different rooms again with the screed installer and explicitly pointed out the different coverings in the hallway and wardrobe. Apparently, he didn’t listen properly to what was planned where, so this constellation arose along with the wrong plan.

Since our site manager is currently on vacation, we have now contacted the central office and are waiting for feedback from there.

I’d be interested to know what options there are now to fix the defect so that it fits afterwards. Or is this not such a big problem after all?
Basically, the screed in the wardrobe would need to be raised by 2 mm, but in the hallway it is now exactly 2 mm too high.

Leaving it as it is is not an option, the parquet will be laid from kitchen/dining/living into the hallway and the study (it will be glued), the transition to the tiles will also be designed without a transition strip, only with a silicone joint.
The remaining heights in the other rooms fit so far.

Thanks!

You can sand down 2 mm. You just have to clarify the question of who is responsible and the costs.

No one will bother about 2 mm. That still falls within the tolerance range. Are the tiles and parquet already available? Then first check the dimensional accuracy. The parquet can be laid and the room to be tiled can be raised by 2 mm with leveling compound. I see no problems with that.

2 mm can be distorted over several meters within a floor covering without being noticed. It's just a question of which can of worms you want to open.

That doesn't sound too bad for now...

The tiles and parquet have been sampled since the beginning of the year and I also think they have been ordered (we are building completely turnkey with a general contractor and have sampled the floor coverings with the respective contracted companies).

We just want to make sure that it fits in the long term and that there aren't any unsightly steps somewhere.

Let's wait and see what the house building company says about it.

No worries, 2mm are practically nothing. They are even within the tolerance of the tiler from one tile to the next within a tiled surface (just barely) (keyword Überzahn).

The screed layerer doesn't even have to guarantee 2mm, by the way.
