193 sqm urban villa with north orientation, is it sensible?

You don't have to get bigger. Distribute the rooms or the spaces differently if there is a pinch somewhere. You still have the huge bedroom. Many fit 2 in the space

But it’s also a matter of price. [...] Many pieces of furniture, except for the couch and TV, are not supposed to go into the living room.

Money cannot be an argument when, on the other hand, the Anstattvilla concept is implemented one third larger than the standard. Simply "just putting fewer pieces of furniture in" will be no more effective than great architecture, as is well known a single swallow does not make a summer. Rather, it is aptly formulated here:

An empty space suggests a room that is not there or too much.

I stick to my point: this must be new, tinkering around here will lead to no success.

I see it the same way. Most people here get a coherent and generous overall concept for 4 people on 160 sqm. And if you allow a necessary half meter on a square floor plan, it results in 20 sqm more, which is not at all necessary unless you insist on the square.

And if you concede a necessary half meter on a square floor plan, it results in 20 sqm more, which is not necessary at all, unless you insist on the square.

On the other hand, if you add the same half meter to one dimension of a previous square floor plan and simultaneously subtract it from the other, you mathematically lose a quarter of a square meter but miraculously gain the feeling of two square meters. The (per floor) two and a quarter square meters black gain from this dirty deal is invested, for example, on the ground floor in avoiding crowding in the cloakroom area :-)

It is entirely legitimate to want a large bedroom. We have explained why sufficiently. If we had divided the room into a sleeping and dressing area (which we do not want) or even made another children's room out of it, no one would say anything. Therefore once again: the floor plan above is fixed for us and it is exactly to our taste. Our question was mainly whether enough light comes into the open space. We are happy to discuss that. By the way, I find hampshire's approach quite interesting. Presumably very few architects and homeowners really ask that. For us, a lot happens around the kitchen island and at the dining table. That is why the kitchen island is to be 1.20m by 3m. I find that quite difficult to implement in an L-shaped open space. Thanks, UJS-Nord, for your drawing! I had tried several times to integrate the kitchen island into another open space layout, but so far I have not been successful. We are not fixed on the square at all. The fact that it will be a city villa is simply due to the fact that we are building a two-storey house; we could call it that as well. Some may not like the term, but that is what it is called. It has nothing to do with a wannabe villa. It is simply a house without pitched roofs.

Is the hallway wide enough?

Yes.

Is the utility room sufficient?

No.

Would you size the house differently (i.e., design it longer or wider)?

Yes.

Would you plan the garden and terrace as well as the driveway, garage and entrance elsewhere to move more towards a south or west orientation?

Yes.

Or is there simply nothing more to get out of this plot?

No.

Our question was mainly whether enough light comes into the open-plan room. We can gladly discuss that.

In my opinion: no.
