Maybe we just made an unfortunate choice of provider.
The question then is whether there is another, possibly better way in this situation.
We also do not know the chosen providers yet. I have already said everything about the better way:
1. show the house in question here
2. have a tender made by the project-managing architect (and do not exclude this general contractor).
So far, we neither know the plot nor the house, how is anyone supposed to say anything about it? It is best to fill out the questionnaire pinned at the top of the floor plan section.
I don't know any companies,
@11ant do you know any or can you remember?
My willingness to do so will depend on how well the OP cooperates here ;-)
