The only success I've had giving building height beyond the surrounding landing was when I cobbled together a Rhine River Map and wanted a castle with a commanding view. I built up a 90 M hill and covered it with mostly impassable terrain with a road up the side then put two Government type buildings on top, one right on the edge. That gives a fairly commanding view of the bridge and surrounding countryside, but you need more than just one spotter or whatever to get a 360 view. Realistically there are still blind spots.

Prosit!
