Single-family house city villa 200 sqm 2 full floors

The question is rather, what does the stub bring to the living room? And generally the question is, what have you actually changed significantly now? Actually, I see a detrimental "improvement" of the initial draft.

For example, the pantry, where it now goes through the curved corridor and the placement options are further reduced.

And, you overlap 3 steps, i.e. on the third step you no longer have 275 cm ceiling height but only 221 cm. But this is especially a head injury risk when coming down the stairs:
Just to make clear what this is about:


Although the dimensions are different, note the descending person.

Moreover, that still does not bring enough depth for the bedroom. It is just 310 cm. A bed with a 180 cm mattress width is about 190 cm wide including the frame. So there remain barely 60 cm on the top and bottom sides of the bed. And then 2 doors in that room, wardrobes have to be placed because the dressing room does not provide enough space. The bedroom will therefore rather feel like a cramped junk room.. Sorry for the harsh words.

Super conveniently .. you then come straight from the dressing room into the wet area of the shower ... no, that won’t work.

I'll send you a private message, I have a floor plan that meets your requirements except for the guest room. You have 4 rooms upstairs for that.

Tom would also take a copy [emoji6]

You do not get a good design from the planner if you ask them to just clean up the bad plan a little. What if you say goodbye to the passage between the dressing room/bathroom and swap the bedroom with [AZ]? Take the area of the [AR] for the dressing room and turn the current dressing room into the [AR], accessible from [AZ].

I would make the children's rooms smaller upstairs. 13m² per room is plenty, and you will have more space for the other rooms. The rest has already been mentioned, like the corner in the living room that doesn't help.

The architect of the general contractor designed this floor plan together with us.

That could at most have been a semi-trained draftsman. At first glance, you can see that someone does not understand the correlation between stone dimensions and the planning grid (and several other things).

With aerated concrete, there is too much sawing involved; with other stones, it is practically impossible to pry it into shape.

In the upper floor, there is an office with three workplaces; I suspect employees (and public traffic?), right next to the bedroom, deep in the private area. Purely from the room layout, I would place it where the guest storage room is planned.

It is not illegal to build people what they have drawn and want to pay for. Whether they will be happy with it is a completely different matter. Once a faulty plan is approved, the construction must conform to it.
