Plot arrangement & orientation Single-family house with 160 sqm south-facing slope

The surveyor's plan confirms my sketches. Excavating the garage so deeply costs almost as much as a basement. According to the stairs at the entrance, a basement is also planned. You have the wrong architect or it is your specifications.

Attached I have included: - graphical part of the development plan (property is marked with X) - overview of property profiles (created by the surveying engineering office) - profile no. 3

Show me the other profiles (and the floor plans of the building project from profile 3). In any case, I clearly read that it apparently does not fit: the garage is most likely allowed at the valley end, and the house should have the axis parallel to the contour lines / to the street.
