As complete "flatlanders," our final age-friendly home (bungalow, prefabricated house with wooden facade) will now be built in the beautiful Leinebergland region. This will be our third new build, and for the first time we are facing a sloped site.
The slope is 10%. The house will be 10 m (33 feet) wide, so this theoretically results in a height difference of about 1 m (3 feet).
We understand that building on a slope means additional costs! We have the following basic questions:
1. What is the most cost-effective way to level the slope (with the street at the lower side) if we do not want to build a basement? (half cut and half fill, or raise the street side completely without soil removal, or something else?)
2. Can the height difference be compensated simply with a strip foundation by increasing the concrete wall on one side?
PS: We do not intend to fully level or terrace the entire plot. This is really only about the house footprint and, of course, the terrace; the rest can remain naturally sloped.
PPS: In the pictures, you can see our plot; it is somewhat irregularly shaped, but well suited for us.
Thank you very much in advance for all helpful advice.

Deciding on a basement is not a private matter when there is a 10% slope, as the terrain clearly has a strong influence. Unfortunately, you can only take symbolic inspiration from Nordlys’ approach to managing differences in ground elevation. In your case, heavy rainwater would rush onto the levee with quite a bit more force, and that is when you learn the subtle difference between drainage and hydraulic engineering. Unfortunately, the information provided by your images does not go beyond being "well-intentioned" :-(

Somehow the plans don’t match up. Do they have different angles?
I would rather build 8.5m (28 feet) by 12.5m (41 feet). Where are the parking spaces supposed to go?
According to the contour lines, the slope is about 12 – 17% in the house area (assuming the contour lines are every meter).
Photos of the plot would also help.
