The section of the map above is oriented to the north. The property slopes slightly towards the northwest. We are now waiting for the first drawing and further details from "Fertigbauer 2" and have an appointment with a solid construction company at the beginning of March. Then I can report more. Regarding the basement, I will seek another opinion, but I am basically done with it. It is also not feasible cost-wise, and then I prefer to invest a bit more in the floor area of the house or the equipment or the outdoor area or, or, or. I also found a map with contour lines drawn in. About 2 of these lines run across our property from southeast to northwest. So about 2 meters of slope? On my parents' property, there are a little more than 3 contour lines. As I said, they built with a finished basement, which is completely out of the ground on the southwest side. That is exactly what we do not want, however; we want to go directly from the living room/dining room onto the terrace and the lawn, which from my point of view also argues against a basement. This terrace/lawn should then naturally have little slope. That would also be a point I would like to discuss with an earthworks contractor at some point, to what extent such a surface can be leveled.
