Our plan for the new building - What next?

Unfortunately also for receiving. You can meet at my place, in the blue CatContent portal which is not to be named here, I have a group called 11ant Hausbau.

On the subject:

We chose a rather unconventional way. We didn’t really compare many construction companies and prices; we basically decided based on reputation and gut feeling. We had friends who built with them years ago and said “we would do it again anytime.” Then more acquaintances and also neighbors. Everywhere you heard only good things about the company.
On the internet, there are probably some clients who had/have problems with them and also sue. But in our personal environment, we only heard positive things. Everyone said “there were a few minor things here and there, but overall great.”
Accordingly, we searched for a house in their catalog as a basis for building. In the first meetings, we discussed our wishes regarding features and already asked for some prices for selection topics. We signed the contract earlier to avoid a price increase, but with a financing clause. At that point, we had clarified the floor plan with the construction company enough to know which rooms we wanted on which floor. However, we still shifted interior walls afterwards and also squeezed in a pantry.
A building permit wasn’t required in our area, but I think that’s where the pressure comes from: the companies want to start building, only then do they get their money. But the building permits sometimes take forever. Our house was prioritized timewise by the construction company because other projects were waiting for building permits. The changes to the floor plans, etc., are all costs for them, so they would have to advance money without knowing if you will ultimately sign the contract or not. That’s why they tend to hold back.

Still, if I were you, I would keep searching if you feel they are putting pressure on you or you don’t feel entirely comfortable.
Our construction company is (I think) not one of the cheapest. But they have a construction performance description that is quite extensive and good, and so far they have been very accommodating. I find it especially difficult with house construction to relate services and costs exactly. Quality is such a difficult factor to measure.
