Single-family house 175 sqm without basement, too big?

On page 7 #39 I uploaded the site plan of the house. The section line goes, as I understand it, from northeast to southwest, so practically exactly along the ridge we planned. Maybe you can better classify it this way? But a basement would still be incredibly expensive, wouldn’t it?

The height data there is very sparse and hardly precisely translatable to the house or its outer edges.

But a basement would still be incredibly expensive, right?

Basement despite what expensive? "Incredibly" no, basically simply calculable: Basement practically means double the floor slab with walls standing at the height distance in between. Outer walls on the valley side come with retaining walls if without basement practically about the same. Outer walls on the mountain side come in addition, as well as load-bearing inner walls. Conversely, above-ground technical and storage rooms fall away. So effectively you already pay more than half a basement if you don’t build one – then better a whole one and you get it for that.

Basement more expensive despite hillside location, that's what I meant

We don’t want to keep the slope in the house area, so we wouldn’t have any necessary retaining walls or exterior walls in contact with the earth. Currently, 45,000.00 euros are budgeted for civil engineering and earthworks. I’m very afraid that won’t be enough. The cost range for earthworks seems to be endless In the long run, I also can’t imagine having a hillside property. You don’t really use a slanted garden properly. That’s why our idea is to level it as much as possible and let the remaining slope in the southwest "run out."
Do you find my plan for leveling naive?

Please draw this with approximate heights. Consider 45k to be too low.

Probably, if I understood it content-wise. I probably have about as little understanding for it as you do for your slope.

I also can't imagine having a sloped property in the long run.

And you think it's enough if Bibi Blocksberg says "hex, hex!"? The slope is there. You can accept it or terrace it; the latter is usually more expensive (so it costs more money, and you pay for it with less beauty as well).

So, I have now tried to incorporate this into the cut as I imagine it. Two variants, one stepped and one sloping. In each case, one meter of height was dug out on the left side and up to one meter was built up on the right side (although the previous terrain profile is not correct in this respect. There is already a retaining wall about 50 cm high, so only 50 more cm need to be built up to a total of 1 m).

please don’t be as mean as you were to Shiny, I’m more reasonable too, promise!! ops:
