ᐅ Our Sloped Site – Concrete Slab vs. Basement

We have a sloped plot and have planned a living basement, which will have floor-to-ceiling windows on the downhill side.
Would you recommend building a basement or a slab foundation with slope stabilization for this kind of incline?
Our current building footprint is 9.12m (30 feet) by 8.5m (28 feet).
There is a slope of about 1.8m (6 feet) over the 8.5m (28 feet) length.

I have attached the survey results (plot 1295) with the elevation profile and our thoughts on the house placement.
Basically, we would prefer to build larger on a slab foundation with a wood frame structure and avoid a concrete basement.
I’m looking forward to your ideas.

The soil report is unfortunately still in progress.
P.S.
The civil engineer would recommend a basement, but I would probably say the same in his position.

Site plan: plot 1295 with blue outline, street layout, paths and markings.

This is partly an emergency solution, but not a planned one for me. Especially since the original poster has neither stairs nor a path, just a wall. Above and below.
This is not practical. There is no other way to access the steep slope either. If we didn’t already have the walls and the excavations, I would never build like this.

The house costs about 240,000 EUR without a basement from a large Swabian prefab home manufacturer.

...this has been largely overlooked here so far. Are you aware that even on perfectly level land you would never end up at 240k? Is the budget secured?

Has the sidewalk to the west already been constructed?

Thank you very much for the ideas and suggestions.

The neighboring plots are still undeveloped, and the footpath has not been constructed yet.

The house could also be shifted eastward or extended to create a full basement. In that case, the roof would be without a knee wall and only partially finished.
