Floor plan planning shortly before submitting the building application

That's exactly what I meant. It's a small but very important difference regarding the question of who commissioned the architect. That's why I also said you would have been better off with an architect doing individual contracts.

I also consider the additional time required for individual contracts to be a myth. You can, but don't have to decide everything. You have to do sampling with the architect as well as with the general contractor. You don't write the specifications, put things out to tender, or evaluate offers; the architect does that.

That's exactly how we did it. We got a local architect, completely planned the house ourselves, and he awarded all trades to local companies.

We do the sampling, make calls, and confirm, but not much more than that.

And apart from a lightning strike damage during shell construction for which no one was responsible and an unreliable stove builder, we had no problems at all.

But we also knew that with our wishes being so individual, no one else could have helped us.

I wish you that the house will be completed to your satisfaction nonetheless...!

And again completely wrong with the prioritization.

Maybe for you.

I am talking about simple things. Is the system sufficiently designed; a look into the datasheet. What do I get, wall, ceiling, or floor outlets and where do they go?

I have written it countless times that the general contractor only provides the planning documents at handover. And even if he had provided them earlier, there would be no possibility for intervention, because nothing is agreed in the contract regarding the type of outlets, etc.

Apart from the fact that floor outlets would never ever come into my house personally.

We have no problem with that and I also do not see why we want to make a problem now at a place where there is none. At the moment there is no reason to believe that the ventilation is not okay.

Why outlets not in the floor?
We have them too

Why not outlets in the floor? We have that too

I don’t understand that either. I also don’t like it when things are spoken of worse than they actually are. Sometimes I have the feeling that one’s own house is being talked down. Yet I’m sure that almost everyone who is not very technically inclined has points at the house here and there that they would have planned differently in hindsight. We don’t know ANYONE in our circle of acquaintances who had fewer problems. On the contrary; most had it worse.

You have significantly more problems than we or friends of ours who built at the same time. I only know one person with more problems than you.

I am sure that you would not have these problems with our [GU].
You have left many things to the [GU] or assumed that he would point them out to you or think things through to the end. He is simply not the right partner for you.

So acquaintances of ours built with an architect and the electrician ran off with the money. In the neighborhood there is a house that has been in shell construction since 2014 - the ETICS is deteriorating - the basement is a dripstone cave. Since then, only surveyors and lawyers have been involved in the house. Also an architect's house.

It can go better than with us; but it can also go significantly worse. And it cannot be changed anymore anyway, it simply has to be completed now.
