Floor plan optimization city villa + fill consideration

I would definitely not call the floor plan a dead end. [...] For the rest, you have to look for solutions without immediately questioning the bigger picture.

It is not the floor plan that is the dead end, but the realization (mine, not the OP's, who is probably too deeply involved and does not see it due to lack of perspective, or at least sees it unclearly), that the attempts to solve the problem are the problem. With every further botched improvement, only the carousel of unsatisfactorily solved details spins a little more desperately. A decisive break is neither a declaration of bankruptcy nor a disgrace; rather, it is an end that contains a beginning. A nail file won’t help with Gordian knots.

Either you stand together in the bathroom, then you don’t need the space-consuming parents’ wing including dressing room, or you both have different wake-up habits, then one washbasin is enough.

I have to disagree. I work shifts, my husband "normal". We are both separated and at the same time in the bathroom. At the moment we only have one sink. I can hardly wait for the second sink during the "battle" over the water stream.

When it comes to the "fight" over the water stream, I can hardly wait for the second sink

if you like to fight.. . No, seriously: if there is space, then you can do it. But take a look at this here. It is completely overfurnished in the area. This applies not only to the bathrooms but also to the master area. If it were an old building, you would gut it, remove one or two walls, and gain some (perceived) space as a result.
To me, it seems like various nice-to-have things are being checked off in the design: double sink, kids' bathroom, floor-to-ceiling showers, privacy screen, dressing room, podium staircase, huge island in the kitchen. In my opinion, storage space, wardrobe, chill area, and the entire master area suffer because of it.
That’s my opinion. But I have to mention again that I haven’t read the 45 pages here and I don’t want to criticize something that has been developed extensively here with a lot of thought behind it.

I actually want a lot of things, it’s clearly nice to have. But I don’t want it at any cost. We also feel left alone by the architect. We are going in circles. He is just a drafter, input never came from him. He knows what we want, but no ideas from him. I didn’t think swapping the kitchen and living room was bad. But he drew this piece of wall with the 20/20 breakthrough 2-3 times and we always told him we don’t want it like that. Now there is an unfavorable protrusion in the guest room. He can imagine that nobody wants it like that. I’ve now realized that you can’t have everything and I’m willing to compromise on the parents’ area as well. Important to me are dryer/washing machine on the upper floor and showers without doors. Whether you come through the dressing room first to get to us doesn’t matter to me, for example. That’s just how it happened. So maybe the bathrooms could be moved to the north, meaning at the bottom of the plan, but then you wouldn’t have drainage in the TV corner anymore, right? There is only one floor breakthrough in the kitchen, that doesn’t bother, or am I mistaken? Maybe I’m expecting too much. But the architect can definitely make suggestions to me. Simply sketch something by hand.

Maybe I'm expecting too much.

I'm afraid so too. Above all, you have to realize that nobody works for you for free.

But the architect can certainly make suggestions to me. Just sketch something by hand.

Yes, one or two. But not a hundred. You can hire another architect and pay him by the hour. You'll be broke before you've even broken ground.

Ok

I take your advice to heart.
Very very first draft.
However, I have now swapped the living room and kitchen. I hope you can recognize my scribbles and what they are supposed to represent.

The washer/dryer no longer fit upstairs, and I would still include the second washbasin with the L solution.

I would have to do without the podium staircase. Since I didn't want this U-shaped staircase, everything started with the stair change.
There should be no projections/drainage in either the office or living room now, right?
