Take sequential pictures through the windows of the other building (every 10 floors or so, or whatever you need to get good overlapping shots), then stitch them together as a vertical panorama. This will give you a shot of the building as if you were looking at it directly from far enough away to see the whole thing equally from top to bottom without the rest of the city in the way. I'm heading out of the house for a few hours, but if this doesn't make sense let me know and I'll try to find a good example and post it when I get back.
It's a bit more work, but I think I would want to try this with at least one building to see how it turns out and to see if it's worth the effort or if you just want to stand at ground level and get a more vertical perspective.
