Urban villa floor plan, single-family house new construction opinions

My tip here is also - ask and visit friends and relatives with children. No person without children can even remotely imagine how much stuff children have and how much parents need for their children. A house without children must/can meet completely different requirements than a house for a family.
That means first and foremost storage space!!! and strategically placed areas along the usual living paths where things can be put down or are within reach. And space to move. Our current hallway, for example, is only 1.20 meters wide right behind the front door, and we could renovate every three months because the walls are scratched and dirty. In front of the bathroom, we also have a narrow spot where the three of us regularly bump into each other in the morning.
And yes, I think children are full-fledged cohabitants whose needs should be addressed instead of thinking they will be gone again in 18 years anyway.

But, you can also "copy" unsuitable (miserable) floor plans.

Yes, the striking parallelism of the two designs very close to the motto ;-) "two fools - one thought" (especially at the pantry entrance really 1:1 the same crap) suggests at least the same source of inspiration according to experience with probabilities. However, I do not (at least "yet") recognize any popular catalog design in it - neither a model house nor a Pinterest / Instagram "bestseller" ...

Take a look at Schwörerhaus. They also wanted to sell us such a pantry...

They also wanted to foist such a pantry on us...

But certainly not implemented in the same nonfunctioning way as in both threads. The idea itself is charming, but you really have to adapt it properly.

So, I have given some more thought to the upper floor, since your justified criticism really opened our eyes, especially regarding the narrow hallway, the cramped children's rooms, and the chaotic dressing room. This is exactly why I registered here. What do you think of my current draft? Of course, it is not 100% to scale, as it was created by me in an amateur program.

Don't be mad at me, but I still find it terrible... You have a lot of hallway space, twisted, accordingly dark. The children's rooms are still shapeless, albeit different from before. I would change the stairs. How about moving them to the left, against the outer wall? Then you could already make a large window and have light in the hallway. Also, you could create an exit to the terrace right next to the stairway. So you wouldn't have to destroy half of the upper floor for this "access."
