Floor plans for single-family house, approx. 140 m², without basement

On the other hand, I would be interested in the age or generation of the family council who think that floor-to-ceiling windows take up usable space

My parents thought that floor-to-ceiling windows would look good. We ourselves are the ones who find non-floor-to-ceiling windows much more practical

I tend to a maximum house width of 7.5 meters. But that is not available in the affordable standard.

It doesn’t have to be an affordable "standard," we have also contacted companies with individual planning. But I wouldn’t find 7.5m width with 12m depth very great either, the gable would shoot up quite a bit. Fortunately, we are also allowed to rotate the house by exactly 90°. That would solve the gable problem, but I still think a more balanced ratio of width to depth looks nicer.

So either mirror everything on the diagonal and thus have the driveway from the west or have the carport at the front on the street, so you would have to turn 90 degrees left from the driveway into the carport.

We haven't thought of turning the carport by 90° yet. Whether we like it – we’ll see – I would say it’s just as little ideal as all the other solutions.
I roughly sketched the different variants on paper again. Have I interpreted your two proposals correctly?
With the variants with the carport next to the house, we don’t find the long driveway ideal, especially since we are only allowed very limited coverage.
For the carport at the top (northwest), I wonder if that works well due to the slope. We would want to place the carport right at the boundary at the top. So now we are there, let’s say, 1.40m higher than at the southeastern boundary. Since the terrain height at the boundary is not allowed to be changed, not even by support walls, the carport must thus be at least +1.20m high. The adjacent house would, in my opinion, have to be at the same height, also +1.20m. Then it stands, without a basement, far above the property.
If the carport is at the bottom (southeast), it may be slightly lower than the house, which seems better to me than the other way around.

Regarding the upper floor: Both children to the west and plan around 15 sqm each. Then you could get a decent storage room.
Downstairs there should also be a utility room and office of similar sizes.
That is not the original floor plan, right?

No, the floor plan is drawn completely free. At some point, we realized that we could also fit the result into the Flair standard outer dimensions. To better compare prices, we initially relied on these exterior dimensions for all inquiries.
Of course, I would also like a more balanced ratio of rooms. We have already tried various other floor plan variants. But something always didn’t fit, e.g., an entrance area inside the house that was too narrow, etc... We probably have to think about it again.

Thanks for your feedback! (even if it unfortunately confirms my doubts )

whether that works so well because of the slope

Now a dumb question again: what kind of gradient do you actually have? Because in the photo in the second post here, there is nothing to see of a "slope." At least not for me.

Hang I also overlooked - from where to where is something supposed to be?

Regards

Yes, unfortunately it is very deceptive, especially in the photo, but also when standing in front of it. We had already reserved another plot, and the slope there did not seem significantly negative to us. Then we measured and it was 1.80m.

The slope in the development area runs overall from northwest to southeast, exactly in line with the orientation of the house. According to the contour lines on the development plan (which can also be seen on the attached excerpt) about 1.50m from northwest to southeast. The municipality has shifted a lot during road construction; I think we now perhaps only have a slope of about 1m. We still need to measure again. But it is definitely more than you think at first glance.

According to the contour lines on the development plan (can also be seen on the attached excerpt)

On which excerpt is this supposed to be visible? I’m at a loss.

On which section should one be able to recognize that? I’m confused

The dashed lines on the Bebauungsplan.jpg indicate height differences in 0.5m increments.
