Door reduction due to planning error and compensation payment

Hi, well, the bathroom is no longer accessible now. You never know what else might come. Regards, Olli

For barrier-free access, the door was also too narrow according to the plan. The door would also have to open outward and not inward.

There won't be anything to gain there, at best a favor elsewhere.

As a guideline, in our granny flat, an open planned passageway of 1.10m between the hallway and living room was made "only" to standard door width. The blue conductor said it would cost him about 250 euros to widen the passage and asked if we would agree to a payment of 250 euros. We took the money and that was it.

In your situation, I personally find it much worse; the narrow passage would bother me a lot.
