Single-family house approx. 160 sqm flat roof - Optimization / Planning

OT: So... with me, there are always ironing piles:

[*]needs to be ironed (blouses, shirts...)
[*]does not need to be ironed (sports clothes)
[*]negotiable (T-shirts...)

I have eliminated point 1 – it goes to the laundry, point 3 is then negotiated with myself until nothing remains on the negotiable pile and everything moves to the middle stack. You can also buy T-shirts so small that they are smoothed out on the body.

Back to the topic:
We have a flat-roof house. Recessed upper floor because of the somewhat cake-shaped plot. So the ground floor is also partly cake-shaped, the upper floor is a cuboid on top.
Was it cheaper than taking the "unnecessary" sqm in the upper floor? At first, we hoped so, but I no longer believe it! In addition, we had a lot of trouble at one point with sealing the cantilevered part of the ground floor. So also consider whether there could be technical construction problems!
Visually, I was immediately love-struck by the architect’s first design and am glad the building was loosened up like this. The projecting parts of the ground floor will still get a green roof, which will make it look even nicer!

At that time, we also started with a straight staircase. By switching to a quarter-turn landing staircase (is that even what it’s called? :rolleyes ) it was only then possible to shrink the sqm together and also to realize the recesses in the upper floor to save even more sqm there. I think our first design was around 220 sqm (there are only two of us), and now it’s about 170 sqm. So: you can save space by playing around with the shape of the staircase!

And one more point: I LOVE my utility room in the upper floor! It’s not huge, but we have several clotheslines for large items in it, storage options, washing machine, and dryer, hand washbasin. I definitely didn’t want to miss that room in that spot again! Laundry is washed (not) ironed according to the above instructions and disappears directly into the dressing room next door!

I have a bit of a hard time with your floor plan and can only warmly recommend this advice to you: do a reset and plan anew! Even if there should always be favorite corners in such a self-designed floor plan, it helps to start completely over and not stick to individual elements (which often don’t even seem so important afterward...). And if a nice architect is involved in the floor plan, all the better. They’ve learned it.

Thank you for your responses! Does anyone have an idea for a podium staircase? We would like to keep the kitchen/dining/living area as it is, we saw it live once and it was great. However, they did not have a guest room downstairs. And do the others also see the position of the house on the plot as "critical"?

I find it too big. The position itself is okay.

Why do you think it is too big? The house or in connection with the garage? The plot size is 567 sqm and the floor area ratio is 0.4... it should fit, shouldn’t it...?

@Escroda or @ypg had pointed out that you are getting too big for the B‘Plan

I meant the double garage (9m*6m) is too big for the property, not for the development plan.

Floor area ratio 0.4

What is set is the site occupancy index – but it still fits.
But I don’t find the double garage fitting with the house dimensions, since the house, IMHO, shifts too far south. Then the house would have to be rotated 90°, for which the floor plan does not fit.

567 sqm

approx. 500 sqm

That’s what I call a generous interpretation of “approx.” Probably has to do with my profession.

I find the offset of the upper floor too small, unless you use it as a balcony, which makes little sense in the north and probably doesn’t save money. But making it bigger hardly works either, since mandatory two-storey construction is set.

Yes, the house with such a garage is indeed a bit too far south. We would like to accommodate two cars as well as bicycles and storage due to the lack of a basement. Turning the house: we wanted to position the house this way because the street runs through the residential area to the east, and there is a dead-end street to the south. We prefer to have a west-facing garden.

The plot size was still included here when we had not yet bought a specific plot, sorry about that.

We are now having it calculated what it would cost if the upper floor has the same area as the ground floor.

Regarding the garage again: maybe just a long narrow garage to get space at the back. And possibly a second parking space in front, if allowed.
