These 2 buildings are able to rotate, yet when you turn them into towers, they revert back and are unable to turn. I had 2 residential complexes rotated and when I upgraded them, they were then stacked on top of each other occupying the same space. The blue residential also does this. My suggestion is to either remove the rotation on the complexes, or add them to the towers.
I think you can't rotate the residential conplex
