Building application to construct 2 semi-detached houses together?

Hello everyone,

we are supposed to submit a building application soon.
Planned are 2 semi-detached houses, each on a separate plot (they stand next to each other, 1:1 symmetrical in shape/size/orientation) with separate builders. We are both building at the same time with the same construction company, the two semi-detached houses are identical and symmetrical.
Question: should two separate building applications be submitted for each semi-detached house by each builder, or is it possible with a joint building application?

Thank you very much!
Best regards
Nils

I am rather cautious about that. It should definitely be planned together, but I would not compile the building application together. As soon as there is something to pay, there is a risk of conflict.

You can only submit a building application for your own property. Builder/Signature/Approval. However, no one prevents you from submitting the building applications simultaneously.

We are also building a semi-detached house together with the neighbors. This is how it went with us. We got to know each other and discussed everything together, wishes, ideas, etc. Then we chose the general contractor together, we were always four people at all appointments. Then we had the architect plan and prepare the building application, everything was finished on the same day. The building application was submitted on the same day and the building permit came back almost simultaneously. The plots are actually divided, not a condominium. Both semi-detached houses look identical, same roof shape and exterior color. The selection process will of course take place separately. So far everything has gone smoothly, except for the crisis-related delay.
