Building ground suddenly a biotope

We also wanted to build with the slope but are not allowed to go that high with the house because the basement must be below. Unfortunately, everything was rejected because of the heights. So the planner and so on said back then it is a possibility but they want to wait and see what comes out and then look further if it can be done differently.

My girlfriend reached someone this morning and they said our case will be decided on Monday

What is the maximum height of the house allowed from the street?

Maybe also post a cross-sectional image of the house and the site in the forum?

I have to check again the problem is that the district office can choose the measurement point on the street whether it measures further from the left, the middle, or further to the right because the street has a slope different values result

We are allowed to build from all instances like this, only the last lower nature conservation authority is against it; if we need to make changes, we have to go through the city council and district administrator again with the forestry office, etc.
