Floor plan design single-family house approx. 170 m² + attic as a modern clinker house

I like the floor plan! The only thing is the staircase, which would not be at all for me. It would bother me if there were one or two steps on the landing. I would probably stumble regularly because my walking flow would be disrupted.

Would a half-turn staircase not be possible there?

Good question regarding the half-turned staircase. It is certainly very tight with a shorter staircase as well leading to the attic. The knee wall height is 0, presumably you would have to crawl up on all fours from halfway up the stairs :)

The type of staircase seems to me more like born out of necessity, an architect should be able to design something better. I currently see the dining table as a bit tight, as well as the sofa. In addition, I would then like to have the table centered in front of the beautiful large window, but maybe that is already too rigid on my part.

I would definitely reconsider the wardrobe and the arrangement of the WC. With children, such a "tube corridor" where the wardrobe hangs in a side wing is more than impractical. I would probably rotate the WC cubicle, push it as far as possible under the stairs, and thus create a small area with corners in the hallway where children's wardrobes and seating can be placed without having to squeeze into a niche.

I think the floor plan is very well done! The staircase is certainly an adjustment, but even that gets easier over time :-)

: Thanks for the hint. The longer we turned the table back and forth, the more we are now back to a horizontal orientation and closer to the window below. Otherwise, we will move the sofa up by half a meter, which will then make the study and the utility/technical room slightly smaller.

Interestingly, we have found that we are currently very satisfied in our house that the laundry is done on the ground floor - so we are canceling the laundry room on the upper floor and placing the washing machine and dryer with the technical room. The architect is currently working on adapting the staircase (away from the half-landing staircase with interruption). On the upper floor, the children's bathroom is to be placed where the utility room is; the utility room will be eliminated. The gained space is to be (if possible) added to the master bathroom, where the bathtub is important to us. If the space cannot be used meaningfully - well, an exciting question on how to deal with it then.

What I find difficult about such decisions is that no one can tell you how construction prices will look in a year or what savings in living space will bring. It's clear that I cannot calculate linearly with the entire sentence (e.g., 2,500€/m²). For Weberhaus, for example, the same house concept with the same rooms, which are correspondingly larger (Sunshine 120 vs. Sunshine 220), costs about 1,000€/m² more for the extra living space.
