But then, it all depends on how close you get to the building, combined with how likely the viewpoint is to change will decide whether you have to go through the hassle of setting up a semi finished 3d scene for it.
I only went the above way over doing it in post because we were looking at pretty drastic view changes, and a *very* strong likelihood of animations coming in the future.
