Purchased house does not meet B plan

40-50k€ extra for stuff that will definitely come with Town & Country you must have planned for.

This is definitely a mistake by the seller, he was aware of the initial development plan but sold me a house that does not comply with the B plan, what should I do?

[*]people can reasonably have a different opinion about your responsibility in the matter and
[*]this reflex automatically leads to confrontation and that would not be productive.

[*]Call Town & Country and report the problem neutrally and factually.
[*]Then also ask neutrally and factually, "What do we do now about this?"
[*]Be sure to let them finish speaking and take notes.
[*]Stay calm no matter what happens. Maybe the solution is already included.
[*]Arrange an appointment at decision-maker level to either confirm this solution or find an alternative. If you are unsure about negotiating, bring a trusted person with you.
[*]Do not sign any agreement during the meeting without reviewing or having it reviewed calmly afterward.
[*]Make a factual and correct record of every conversation, which you also send to your contact person – always with the request to correct it if anything has been misunderstood or incorrectly reported. (No correction creates facts)

I bought a 1.5-story house from Town & Country,[...] planning with the developer was also completed,

So I wouldn’t immediately involve a lawyer, but first calmly gather detailed information:

- Have you actually read the development plan yourself? Does it really say that only 2 full floors are strictly allowed?
- Who exactly wanted to submit the building application? You have to be authorized to submit it, like an architect, civil engineer, etc.
- If the development plan really prescribes 2 full floors, I would talk to your building authority to see if they can imagine an exception. Usually, it is less problematic to build smaller than allowed than bigger.
- Possibly you just submit the building application like that anyway and hope it gets approved.
- Otherwise, I would discuss with Town & Country what would need to be changed to make the house have 2 full floors. Maybe a slightly higher knee wall / dormer, a slightly flatter roof, or a slightly higher clear ceiling height in the upper floor would be enough.

Most people rather have the problem that 2 full floors are not allowed and have to reduce the house to 1 full floor (1.5 floors don’t really exist).
