Should a hanging plot be filled for a ground slab?

if only I knew first whether it’s a residential basement or a utility basement.

Sometimes I think you don’t read everything. Weren’t we already at this point: partial utility basement? So partial basement below, on the valley side, with a side-accessed adjoining room. Even in a utility basement you can have a toilet and a shower. And of course you are allowed to put a cozy sofa bed, reading chair, etc. in a storage room, even on a nice carpet. When I stay overnight with friends, I’ve never checked whether the guest room is also called that in the building permit plans. Or even looked behind the wallpaper to see if the plaster is Q4 or measured the room height of 240 cm. I think you’re overthinking this little basement construction too much, just chill. No police will come at night and ring your visitors out of bed if they’re sleeping in the “storage room.”

Are the square meters enough for you? Barrier-free costs space and your room program was not small

Unfortunately, a lot is in the other thread…

In the bedroom I would like to have a small fixed place for the change of clothes for each of us,

Is that called a wardrobe?

The plot has now cost 95K. For the house without additional costs, that leaves 300K.

That is tight. I’m surprised that you have such a house with gigantic window area in mind (other thread)

That’s true! I am already redesigning, if only I first knew whether now a living basement or a utility basement.

Phew, hillside houses ALWAYS with an architect!

Sometimes I think you don’t read everything.

Me too. I hope that no more threads will be created.

The plot now cost 95K. So for the house without additional costs, 300K remain. We will at best offset the rising construction costs with the theoretically also increasing selling price of our current house. The squaring of the circle

Just because construction costs rise does not automatically mean an increase in the value of existing buildings. I actually just wanted to ask here if you have thought all this through. You are building for old age? Then why this steep slope? Were there no level plots, or does the house have an elevator? But the view is of course absolutely stunning!

Not everywhere has flat land.

Not everywhere has flat plots.

Yes, but the combination of a slope, low budget, and retirement home is quite far from ideal. And 19% is not just a slight slope, that's steeper than most Alpine passes.

19% is flatter than half of my garden. I would be glad if I only had 19%. Ideal rarely exists in construction. The OP has set a goal. To build debt-free, in that location, age-appropriate. It is not entirely impossible, it is just not easy.
