Hello ,
You say you are ready to move out and bear the costs (I think there is little that can be done legally). Are you aware of how high the costs are? New screed + floor coverings + possibly underfloor heating + removing the old one first. I don’t really have an idea of the costs but it feels like we are quickly looking at €50k and more. Are you aware of that?
No, nothing can be done legally, that is also not our intention, since we have basically done the interior construction ourselves through third-party providers, recommendations are not a binding obligation. We are well aware that with professional support the costs of the measure go far beyond €50k and are also willing to invest if the house thereby obtains an acceptable living condition.
Attached are also two photos of the floor construction.
I would be very grateful for information on experts who can help further.
Best regards woodhouse
