ᐅ 10% Slope - Who Has Experience with Building on Sloped Land?

Hello everyone,
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.

Could you please upload the left image again showing the entire plot? Where is north? Please label the contour lines with elevations. The plan is oriented with north at the top. One contour line represents a 1 meter (3.3 feet) elevation change.

The plans somehow don’t seem to match. Do they have different angles?
I would rather build something around 8.5 m by 12.5 m (28 ft by 41 ft). Where will the parking spaces be located?
According to the contour lines, the slope is about 12 to 17 % in the house area (assuming the contour lines represent meters).

Photos of the plot would also help. Yes, that is roughly what I had in mind as well. And yes, the contour lines are spaced per meter (3.3 feet).
