ᐅ Help with Interpreting the Zoning Plan / Development Plan

Hello.

We recently purchased a building plot and now want to construct the largest possible multi-family house on it. It is an old development area, but there is a zoning plan with only a few regulations. The terrain slopes downwards from the street. As I interpret it, the two full stories apply to the street front, but due to the slope, there could be more floors toward the garden side—or am I reading the plan wrong? I think so because the building mass is divided in the middle, marked with a different color, and the symbol for the maximum number of full stories only appears on the half facing the street.

So, just as a very rough sketch, I have a question for you whether something like the rough drawing could be possible based on the zoning plan.

And regarding the 8 meters (26 feet) on the left side of the building—does this mean I need to maintain an 8-meter (26 feet) setback to the neighbor’s boundary with the residential building?

Thanks in advance for your answers.

Best regards and have a great weekend.
