How high does the house rise - how high to pile up earth (cellar depth low)?

You rejected almost all proposals on more than 10 pages almost immediately.

Overall, I can only emphasize once again that if you didn't have a professional involved in the planning from the beginning, you urgently need to bring one on board now!!! This needs to be seen and assessed on site. Pictures often do not show the whole reality. Possibly simpler solutions can be found, or there may be even more difficulties than the pictures show. I still see the topic of drainage as one of the most interesting topics.

Do you also have a cross-section in the other direction with the desired terrain profile?

Unfortunately, only copied by hand.

Here is the view from the back:



The upper line with point 1) means "Planned terrain at the new building". Middle line "2)": Existing terrain at the property boundary. Lower line point 3): Existing terrain at the new building

View from the front (with single-leaf terrace door):



The upper line with point 1) means "Planned terrain at the new building". Middle line "2)": Existing terrain at the new building. Lower line point 3): Existing terrain at the property boundary

And is it drawn exactly like that in the building application?
