Windows have different parapet heights - Still within tolerance?

With curtains in the corners, you could certainly conceal that. What is that rectangular opening in the top corner?

It also happened to us. I thought something like this would be unlikely with prefab construction - but the specifications were misinterpreted in the design and the surprise came during the kitchen measurement.

Oh interesting that it happens to others as well. Did you receive any "compensation" for it, or did you just have to accept it

Curtains in the corners could certainly mask it. What is that rectangular opening in the corner at the top?

We actually didn't want to hang curtains there. That in the corner is the cover of the anchoring of the concrete prefabricated parts, it has since been plastered over and is no longer visible.

We are facing the same question - have recorded our displeasure in writing and will also include it in the protocol during the final inspection. On the outside, we were able to conceal the error, inside it is not as visible as with you. But the countertop in a separate part of the kitchen will now be almost 2 cm higher than planned. I don't think that's great, but it's not overly dramatic either.

Could it be visually concealed for you by adjusting the height of the inner window sills slightly?
