Plot with a north-facing orientation, how to position the house

First the picture directly, it is about plot 12.

What kind of path is on the left side of the plan (?), how is the topography supposed to be imagined (I see a planting strip in the north, and a slope up or down around the entire plot block)?

What kind of path is that on the left side (?), how should one imagine the topography (I see a planting strip to the north, and a slope or embankment around the property block)?

Hi! That is a pipe that is led from the north side (drainage) towards the street. It therefore concerns pipeline rights. Otherwise, many thanks for the answers, that reassures me a lot :)
