Floor plan design of a 130 sqm city villa with two full floors

130 sqm with an office and utility room on the ground floor I consider almost impossible.

We can only manage this because the utility room is in the basement.

I also find the floor plan rather semi good.

What kind of sport is supposed to be activated there in that extra room? Is it really necessary? Can't it be omitted in favor of the kitchen/living room and utility room? Maybe move the chairs around elsewhere?

ok, thanks for your honest criticism. Honestly, we didn’t really expect that and are now a bit surprised. :)

So it doesn’t necessarily have to be as square as it is now. It was an idea from us that the architect implemented as we wanted.

If it is more rectangular, would that allow for more?
We really like the T-layout in the bathroom. As long as the toilet isn’t immediately visible but smaller, that’s fine with me. You just have to clean everything anyway. :)

It should be two full floors, that is important to us.

We built a T-bathroom ourselves. It looks good, but please not under 10m2!
Do you really want the toilet directly in view of the window? Maybe swap the position with the shower...

If it is rather rectangular, would more be possible?

Unequal-sided rectangular is not generally better or worse than square. It is just like this: square "as a principle" can only be afforded under the condition of taking the longer side as the standard and extending the shorter one to the same measure. If, on the other hand, one achieves a square only by going halfway through the adjustment by shortening the longer side, then it pinches.

I therefore advise first to establish the room program and then to let oneself be "surprised" whether the measurements coincidentally end up equal in both dimensions with clever room arrangement or not.

Before someone complains again that this has to be read seven times as abstractly: here is the translation into a numerical example: assuming the exterior dimensions of a well-divided room program come out to 8 x 10 m; then one can make a square out of it if one can afford to extend to 10 x 10 m. Having to make 9 x 9 m out of it puts pressure on the "longer" side.

We really like the T-solution in the bathroom.

For all details that one finds somewhere great, the rule applies: one should beware of wanting to replicate them in a smaller house. With the present house size, one typically has a quintupled basic layout: one half divided into two (two corner rooms directly adjacent) and one half divided into three (two corner rooms with stairwell/hallway in between). A "T"-bathroom layout is as heavy a burden for the overall floor as a square dogma.

Both dogmas must be "affordable": a square dogma can be borne by a layout from about 120 sqm living area (per floor!); a T-bathroom layout perhaps from about 90 sqm. The size planned here of about 65 sqm per floor is overstrained by both. An island kitchen dogma weighs about the same as a T-bathroom layout; a U-kitchen or a dressing room are slightly lighter.

Roughly speaking, I would say that one has to be able to afford a twenty percent area surcharge for the "square principle" if it is not to be paid for somewhere with cramped room dimensions.

130 sqm with office and utility room on the ground floor I consider almost impossible.

The study on the ground floor seems to me, with all due respect, a leftover area declared useful. In the basement one would call such a room a "hobby room."

Here, however, with the consequence that the kitchen is just a bit bigger than a kitchenette, more like a kitchen in a single-person household or vacation apartment, but not a kitchen for a family of four. A Christmas dinner can then only consist of potato salad, and baking cookies is out of the question. I don’t even see space for a coffee machine or a refrigerator [emoji20]

I also find the kitchen much too cramped. I would completely do without the kitchen door here and rather accept the detour.

The best thing is for you to draw a dream kitchen with real measurements here and take a look at it.

I think you will really have trouble fitting plates, pots, coffee machine, toaster, etc. in.
