OT: So... with me, there are always ironing piles:
I eliminated point 1 – that goes to the laundry service. Point 3 gets negotiated with myself until nothing remains in the negotiable pile and everything moves to the middle stack. You can also buy T-shirts small enough so that they smooth out on the body.
Back to the topic:
We have a flat-roof house. The recessed upper floor is due to the somewhat pie-shaped lot. So, the ground floor is also partially pie-shaped, with the upper floor as a simple rectangular block on top.
Was this cheaper than including the "unnecessary" square meters on the upper floor? We hoped so in the beginning, but I no longer believe it! Also, we had a lot of trouble with the waterproofing of the cantilevered part on the ground floor at one point. So, consider whether there might be technical construction issues!
Visually, I was immediately smitten with the first design from the architect and am glad the building was made more open this way. The projecting parts of the ground floor will get green roofs, which will make it look even better!
We originally started with a straight staircase. Switching to a quarter-turn stair with a landing (is that what it’s called? :rolleyes) made it possible to reduce the total square footage and also realize the recesses in the upper floor to save even more space there. Our first design was around 220 square meters (we are only two people) and now it’s about 170 square meters. So: you can save space by playing with the staircase shape!
And one more point: I LOVE my utility room on the upper floor! It’s not huge, but we have multiple drying racks for large items, storage space, washer and dryer, and a small sink. I definitely didn’t want to do without that room in that location! Laundry gets washed, (not) ironed as described above, and goes straight into the walk-in closet next door!
I’m having some trouble with your floor plan and would only offer this advice: do a reset and plan again! Even if a self-designed floor plan already has favorite corners, it helps to start completely from scratch and not cling to individual elements (which often don’t seem as important later on…). And if a good architect is involved in the floor plan, even better. That’s what they’re trained for.
- needs ironing (blouses, shirts...)
- does not need ironing (sportswear)
- negotiable (T-shirts...)

Thank you for your replies!
Does anyone have an idea for a half-landing staircase?
We would like to keep the kitchen/dining/living area as it is; we have seen it in person and it was great. However, they didn’t have a guest room on the ground floor.
And do others also view the house’s position on the plot as “critical”?

I think it’s too large. The location itself is fine.
@Escroda or @ypg mentioned that you are becoming too big for the building plan / planning permission Why do you think it’s too large? The house alone or including the garage?
The plot size is 567 m² (6100 sq ft) with a floor area ratio of 0.4... it should fit, right...?

@Escroda or @ypg had pointed out that you are becoming too large for the zoning planI meant that the double garage (9m x 6m) (30ft x 20ft) is too big for the plot, not for the zoning plan. mmmmbau schrieb:
Floor area ratio 0.4What is specified is the site coverage ratio – but it still fits. However, I don’t find the double garage with the house dimensions appealing, as in my opinion the house shifts too far south. Then you would have to rotate the house by 90°, which doesn't suit the floor plan.

approx. 500 sqmThat’s quite a generous interpretation of “approx.” Probably related to my profession. I find the offset on the upper floor too small, unless it is used as a balcony, which makes little sense in the north and likely doesn't save any money. It can hardly be any larger anyway, as a mandatory two-story design is required.
Yes, the house with such a garage is indeed located a bit too far south. We would like to accommodate two cars as well as bicycles and storage space due to the lack of a basement.
Rotating the house: we wanted to position the house this way because the street runs through the residential area to the east, with a dead-end street to the south. We also prefer to have a west-facing garden.
The plot size was still included here when we had not yet purchased a specific lot, sorry for that.
We will now have calculations made to see what it costs if the upper floor has the same area as the ground floor.
Regarding the garage again: possibly just one long, narrow garage to create space in the back. And possibly a second parking space in front, if allowed.
