The thing with the 3 sinks was meant more as a joke than seriously.
But I read a different reason from you, and that's also how it is drawn in the draft. From my own experience and from our surroundings, it is like this: your growing kids will no longer stand side by side at the sink and giggle. The older one is more likely to go down to the basement (where his room might be) and want his peace, and the other(s) go to the parents' bathroom or the ground floor. I had a similarly dreamy misunderstanding in my imagination 30 years ago, so maybe I can somewhat put myself in your situation.
The same applies to the topic of architect and relatives’ opinions. I was also told back then that architects are expensive and usually not good, and that you can do everything yourself. Check how your advisors themselves live, then you can better assess their statements. Do you want to live like them? Politely but clearly tell the lady that you don’t like that, and have her make 2-3 drafts, if necessary hand-drawn on a sheet as a basic idea. And hold back a bit, even with frills, because later there won’t be enough room for diversity in many ways.
On the ground floor I just think we don’t have that many options.
Not infinite, but quite many that you, as a layman, just can’t imagine yet. Even if the building shape were to change…
Podesttreppe
Could you please erase this word from your vocabulary? You are thinking about things that maybe will never appear in a fancy floor plan. You are not the one planning!
Maybe I should say exactly that…
Yep, Ms. Meier, I have to tell you that I don’t like it that way. This kind of interaction won’t necessarily be different with a freelance architect. It’s even expected; how else should she know you want it differently?
Honestly, I hoped that one of the planning geniuses here would make a "dirty" counter-sketch with which I could then "help" her.
Please get out of therapy mode again. If she really needs this, then get up and leave immediately. Or do you just like making diagnoses—
Slowly we are just desperate because unfortunately we are under time pressure
Extremely bad prerequisite… I think the problem is not that big. Talk to her and also have her recommend something to you; she should make suggestions for you. Let her really do it all alone, alone and without podesttreppe, 3 sinks, garage width, etc. Maybe then the knot pops and you can make adjustments in your sense afterwards.
Don’t be mad at me, but I think you are a bit too fixed or stubborn there, maybe also because of the time pressure. Let her do it, all alone, and then post the drafts here. Maybe she’s also just doing what you want so that she has her peace—
