Architectural house floor plan with staggered floor

I will not address the construction costs since a price elasticity has been indicated. Therefore, I will not discuss the economic efficiency of individual solutions but rather their benefits. The design works wonderfully for family life, is exceptionally spacious, and hopefully has a ceiling height > 3m at least on the ground floor to make an impact.

Your concerns about the living room and lounge:

I would leave the living room where it is planned. Even if you cannot set up full privacy from the street, you can use Venetian blinds if you want to be unnoticed. A large window side can still remain open for daylight. For this reason, the small lounge also makes sense because you are very private there and have evening sun. It is a nice luxury to have several favorite places to settle, the studio could also become such a place, especially if a large roof terrace is created. For real privacy, the plot is too small, and the neighbors are too close. Of course, your ideas and needs are paramount – these should serve as instructions to the architect. It is much better to say to him: in the living room, we want maximum privacy and to let the architect find a solution than to suggest a direct room swap.

Size of the walk-in closet:
In this format, a walk-in closet is really practical. Wardrobe space, mirror, and centrally a place to sit down and spread out clothes. I would save myself the many small fashion-prestige-walk-in-closet solutions you see here. Either do it properly or not at all. Well done by the architect.

Passage to the garage:
"I find 'too American' funny as a disadvantage attribute. Arguments against the passage might be heat loss and odor. On the other hand, convenience. It suits your design – although probably in practice not all groceries will be driven into the garage.

Format of the study:
I find it completely OK. If a laptop is enough, the terrace, the lounge ... will certainly sometimes be used for working as well.

House connection room in the basement:
Cleverly placed – and there is also space for a cooler area for wine, potatoes...

Storage room on the exterior wall:
In most houses, this would be a waste of a window spot. The rooms overall are flooded with light due to the large window areas, so it works here. You do not have to make a dogma out of it.

Long hallway upstairs:
I do not like traffic areas that have no use. Here the benefit would be creating a certain seclusion of the master bedroom. Since the hallway also has some wall space, it offers space for art. Certainly, there would be more compact solutions.

What I like little:
is the ratio of house size to plot size. Such a spacious and individual house deserves more space to also have an impact outwardly (was one of the clients’ goals). I find it a bit unfortunate if so much area is sealed – on the other hand, I am aware that it is also not a solution if everyone who can snatches building plots from others to have a larger garden and more space. I would be tempted to take adjacent plots as well (provided the financial elasticity and availability were given).

Nice project that will certainly require very much more calculation. Good luck!

Could the living room be easily swapped with the kitchen due to the pipes from the bathroom above?

How wide would the garage be?

do not exchange. That is impractical

Just don't swap ;)

And, I would mirror the kitchen, on the right side of the plan possibly the pantry with integrated tall cabinets, terrace exit a bit further to the left, and then you have a row on the left where you can nicely integrate a south-facing window.

I find the garage passage rather unfavorable.

And in the living area, I would not necessarily use floor-to-ceiling windows on the street side .. I would probably avoid floor-to-ceiling windows there altogether. Due to the suggested sofa position, which I also consider sensible, in my opinion, windows with sills are sufficient and thus provide much more privacy and coziness.

Office: M 100% home office, W home office 40-60%, two separate offices needed

Home office setup:
I find that completely OK. If a laptop is enough, the terrace or the lounge will surely be used for working sometimes.

I just can’t get it out of my head that someone is building a 250 sqm house with a project volume of 1 million euros and then is supposed to spend at least 8 hours a day in this shoebox? The room doesn’t have to be as big as the children’s rooms, but it should be about 3m x 3.5m or that size if I still want to spend 44,000 hours in this room until retirement.

I assume that the OP’s name is Stefan and that M is the one with 100% home office.

In my eyes, the draft (why does it actually have no views, would that have been image 02?) reads like a narcissism diagnosis of the architect; I also suspect him to be a professor or private lecturer.

First of all, I notice that the house at best fits the plot on paper. Even without a fence, it is still relatively a block, and would do well with about ten meters more free space on all sides to bring out its sculptural effect. Overall, I see here a house for high-earning dual-income households (both full-time, hardly significantly below senior public prosecutor / chief physician). In the first place, I see at least an "8". Roughly calculate the basement as a full basement, also the studio as not being a recessed story in terms of area, then you will come closer to the suspected true price.

Additionally - not yet factored into the above! - I see a frighteningly large "Factor X" for the terrain modeling. One meter ten in what form, and especially what kind of adjustment to the existing terrain (you do speak of already existing neighboring buildings on the opposite side of the street)? - how should this affect the heights, even though I read nothing about eaves or wall height requirements?

The basement is a joke. Partial basements are generally all the more uneconomical the smaller they are. Here it also recedes on all sides; I essentially only see a lighting possibility under the entrance door (???), and also the house entrances will probably be inevitably built over (after entrance, lounge etc. one of the indicators I read as hints of a non- or no longer practicing architect). Whether one places the media distribution in the basement given an expected half-meter flood, I mark with another strongly furrowing question mark.

This is the architect's first draft, i.e. I see it as a basis for further revisions.

Does he see it that way too, i.e. is this a "preliminary draft" (usual in 1:200 scale, in any case belonging to performance phase 2)?

Finally, my reading tip, to which thread I feel reminded here:
