ᐅ When is it considered a construction defect? A wall misplaced by 10 cm

Hello everyone,
I have a problem and honestly don’t know how to handle it. I am currently building a timber house, and a major mistake has occurred. The house is a single-family home with both a ground floor and an upper floor. During construction, I noticed that a wall on the upper floor was misplaced by 10cm (4 inches). Because of this, no bathtub fits in the bathroom anymore. My question is, what rights do I have regarding this faulty workmanship? The wall can’t just be moved since the roof is already in place. Additionally, the walls on the ground floor are also all shifted by 10cm (4 inches).
What can I do, and what rights do I have?

What does the contractor say about it?

The company admits that it was their mistake with the wall because they overlooked a measurement in the drawing, which caused the error.

10 cm (4 inches) is a defect. The question is whether this defect can be remedied considering proportionality. Information is missing for that. Planned versus actual design.

How large is the planned bathtub? I can’t imagine that there isn’t a smaller one available.

My negotiation goal would be to find a very nice bathtub in the right size and have the additional cost covered by the construction company.

Hello, then you have a goal and, in my opinion, a fair offer from your side.
