Calculation and planning, your opinion

I would like to mention again that this is the wrong subforum for floor plan discussions. I believe there is a separate one for financing data as well... Be that as it may: I could also explain very well based on your designs why this and that is not feasible, stupid, or pointless, but unfortunately only when I find more time for it.

The floor plans don't work at all on the slope. Or am I missing something?

That's right. I had written something about this here:

I would actually build a bungalow here, but without a basement, if the money is to be used sparingly. In the north, it will sink somewhat into the slope, but that doesn't matter if you place the utility rooms there. If necessary, you use skylights; they provide nice light.

I hadn't planned a bungalow at all.
A small two-story with living/dining/kitchen upstairs with open gable
Stairs for a stairlift
Downstairs sleeping, utility room and building technology

I personally don’t even know what I proposed back then Anyway: A bungalow is favored here... then the rear north half must be built into the plot. Thus, the northern windows are omitted. Accordingly, the rooms must be arranged and planned. Putting this problem aside, the first draft of the three in #15 is criticized: useless slanted partial wall, causing unnecessarily much unused free space in the hallway. The slanted wall also makes this wall in the utility room only two-thirds usable, because otherwise one would bump from the door into a furniture corner or something like that. The WC, that is the toilet, is wedged into the niche of the washbasin, making it hard to use as is. The slanted wall does not make the dressing room roomier, rather the opposite. The bedroom must be estimated about 2.50 m wide, 3.80 m long. With a standard double bed of 220 x 210 width it can’t be accessed properly. At the foot there remain 60 cm. Bathroom: The washbasin unnecessarily narrows the path to the shower. Nobody needs a window in the shower except the neighbor. Guest room is comparatively large in relation to the bedroom. For what purpose? Living area has half unused space. I see half a kitchen, where is, for example, the fridge? Completely unergonomic: a cabinet in one corner, 2.50 m between cabinets... the pantry is not advantageously located near the entrance. That’s enough for now. The other two are even more extreme in their execution. Just go to an architect who knows about slopes. How does the neighboring development look like there??

Neighboring buildings are a mixed variety. Mostly 1.5 .... but also 2 storeys. There is also a basement bungalow. Mostly gable roofs, but also shed roofs. No flat roofs.

The question is:
Dig into the slope, build the basement halfway in and put a bungalow on top?
Or not dig at all, fill up from the south and only build a bungalow.
Split-level is out of the question because of constant climbing stairs.
If it were up to us, then completely without stairs. Fill up, and only a bungalow. Next to it, facing the street, a larger double garage. The plot size allows that.
The bungalow would then be positioned as far north (up) as possible. Then it should not disappear into the slope either, since above the slope there is no more slope. There is the parking lot of the Catholic church. If you know what I mean...

What does

The floor plans don’t work at all with this slope. Or am I missing something?

mean??

Fill up, and only bungalow. Next to it, towards the street, a larger double garage. The plot size allows for that. The bungalow is then pushed as far up (north) as possible. Then it shouldn't disappear in the slope either, since above the slope there is no more slope.

Although with 35 meters depth you theoretically distribute the 7 meters of slope over the length, if you say that there is no slope to the north, then the rest is steeper. It doesn't help to just place a house on the edge. It usually also looks stupid.

Such a large slope has to be modeled. For that, you need to know the plot.

Split-level is out of the question because of constant stair climbing. If it were up to us, then completely without stairs.

Hard to believe
