City villa subtly modern 218 sqm

... to put it harshly: "Symmetry (alone) is pseudo-aesthetics for those with proportion dyslexia."

That is not harsh at all, but a wonderful bon mot. I am certainly a proportion dyslexic, but I think that if you do not have almost unlimited financial resources, you can make fewer aesthetic mistakes -->with symmetry than -->without symmetry. Ultimately, however, it is perhaps a matter of taste anyway. Admittedly, the beauty of many houses escapes me if they are not Art Nouveau villas or the like; proportion dyslexic hits the mark exactly.

I am certainly a proportions dyslexic, but I think that if you don’t have almost unlimited financial means, you can aesthetically make fewer mistakes -->with symmetry than -->without symmetry.

On the contrary, and that is also why I alternatively used the sharp wording: to urgently warn against placing any hopes on symmetry. It is by no means suitable to prevent awkwardness in appearance. With "asymmetrically ugly," one can at least "console" oneself with the misconception of having found the "culprit" in the "missing" symmetry for why one does not like it; with "symmetrically ugly," the effect is the same – but you additionally cannot name what it might be due to. The probability of landing at least random hits as a proportions dyslexic is significantly higher if you do not eliminate randomness through symmetry. By the way, lack of wealth is not a good excuse: layman-friendly and free explanations, for example of the "golden ratio," can be googled by any halfwit in a few minutes; that is no art. Integer approximations can also be found lightning-fast with the keyword Fibonacci.

despite the relatively large living area, I am missing a proper wardrobe, which can certainly be designed as an independent room.
Similarly, the space available allows for a medium-sized pantry. It's all just a matter of the stairs and their position
I would also somehow connect the garage to the house with a roofed structure so that you can go back and forth protected from the rain.

I really like the layout upstairs. You can certainly create a wellness temple in the bathroom!
Unfortunately, I consider the budget to be insufficient....

Megaflure, 10 sqm room for clothes and a space-saving staircase... well, if you like it...

On the area of the upper floor, we had three children's rooms, a bedroom with a dressing room and a master bathroom, as well as a children's bathroom fitted in. The house can either be sensibly downsized and equipped with all sorts of bells and whistles, or you keep the total area and are aware of the wasted space and at the same time uninspired implementation.

I rarely give my two cents on floor plans, but here I just see a desire to build as large as possible. Regardless of utility and architectural finesse. I just had to get that off my chest.

I am honestly also surprised. With that size, I would have expected something different. You don't have more space as people with easily 50 sqm less, but still don't feel like you have more storage etc. If you can't manage it yourself (and that's not a criticism, for example, I have no knack for it at all), then my first step would be to go to an architect or a good planner. After all, they have learned that
