Semi-detached house once with and without a basement! Who pays?

Here is a lot of dangerous half-knowledge going around again:

This is usually regulated in the neighborhood laws of the states - however, each federal state is responsible for this itself and all differ partially from each other.

In BW it is regulated as follows: if the slab builder builds first, then the basement builder can demand a deep foundation for the later basement depth from the slab builder on his side - however, these costs are then borne by the basement builder.

However, if the slab is built first, the basement builder would have to support the slab at significantly higher costs, hence the possibility of the deep foundation.

So for BW it applies: the basement builder has to pay for the retaining wall - and 10k is absolutely market-appropriate. That would have cost our approx. the same.

I would say it is regulated similarly in NRW as in BW - assuming that the original poster, as indicated in his profile, is also building there.

I don't see it that way. If anything, this better execution should be borne by the neighbor. The base slab does not load the basement. I remember that had similar issues with his house. It was described in detail there. Maybe he can explain it. But again, what kind of contract is it now? If it is a property developer and signed, he couldn't care less. He ordered the house without a basement for price X. Best regards! mini

Hello Mini, It is a property developer contract. The house is ordered for the price of 295,000 EUR. Without basement with 160 m2. Except for painter and flooring work, everything is included.

I would say that in NRW it is regulated similarly as in BW - assuming that the OP, as stated in his profile, is also building there.

Hello Goalkeeper,

thank you very much for the information and to everyone else as well.

Finally, a discussion without blame or the sentence how can one build a semi-detached house and then also without a basement, etc.

May I ask you to write to me as Goali? Unfortunately, I am not allowed to contact you personally because I do not have 100 posts
[E-Mail]faruk-64@live.de[/E-Mail] would be my email

Best regards+

It is a property developer contract. The house is ordered for the price of 295TEUR.

One could only buy a house including the land from a developer, but then hardly for this price.

Finally a discussion without blame or the sentence how can you even build a semi-detached house and then also without a basement etc.

With joint planning with the sparring partner, there is nothing against a semi-detached house. Having no basement only makes no sense if the plot would require one, or if you then end up building one above ground anyway.

Thank you for the information. I bought the plot separately. Then I probably have a contract for work with a GU ???
