Should a hanging plot be filled for a ground slab?

I don’t want to hijack this thread now :D

That’s exactly what I’m talking about. That’s just not true.

What isn’t true? That we spend about 90k less by leaving out the basement?

The picture clearly shows what else is coming regarding the usability of your property. The property also costs per square meter, and every unused one is wasted. Embankments etc. But obviously, we’re talking past each other. All good.

What else is coming? Cattle mulch on the slope and the wooden terrace above, I already wrote that. Surely won’t cost 90k. We’re now only talking about my property: by embanking, I even gained 4 m of level usable space along the rear property line ;-)

Bark mulch? The slope must be planted. Should the next heavy rain wash everything down? In addition, the care is done with the finest handwork

I have even gained 4 m of flat usable area along the rear property boundary by piling up ;-)

... and from the gained plateau a view of "trees without lower trunks," and due to lack of runout, the toboggan needs very good brakes ;-(

So I think that we will be very satisfied with both the trees and the sleds :D

there is not much to see yet, the floor slab isn't even there.

I think the OP was asked, since after all it was about the Elk house.

But you are. Already since your #18.. I'm reading on my phone and had to scroll first because of your "I have" statement (or not ;)) to see if Clarissa was writing.. because it's about her problems.

Let's not turn this into a pro & con basement debate here. The OP asked a clear question.

And the answer to the question, when calculated honestly, is no. Two points:
1. Of course, you can pile up the soil as you did. But making the slope area safe and manageable is incredibly expensive. And dead space is also expensive because you still have to secure it and usually plant it. Every planting needs maintenance. Maintenance on a steep slope is dirty work.
2. You are calculating the same house once with a slab and once with an additional basement. But with the slope, you can well accommodate living spaces in the basement and usually save yourself a whole floor. You have to honestly recalculate that against it.

And I find the 90k savings very high, even if you ignore slope stabilization and planting—after all, layered compaction also involves quite a bit of work. And a 90k surcharge for a basement seems high to me even on a perfectly flat plot.

PS: Plant two trees right on the edge at the correct distance for a hammock. That's the only way you'll float above it so nicely.
