Why is the design as it is now?
The plot is in a good urban location. Therefore, the allowed building density should be used almost to the maximum. Floors should be easily separable. Renting as apartments should be possible without major remodeling in case it becomes necessary.

It would be logical to place the house as far north and east as possible. However, this would completely block the southern exposure of the northern neighbor. This has already been suggested by planners but is out of the question for me. On the other hand, the neighbor is willing to agree to terrain modifications on their property if necessary. Placing the house to the west is difficult due to required setback distances, as the plot narrows. A terrace house placed fully to the west would be possible but is not desired.

I am fully aware that the design is suboptimal in some respects. Therefore, I appreciate any criticism, comments, and suggestions.
