When shooting architecture for architects you often wan’t to show the building in its environment, not just the building itself. You can really only appreciate what a building is (what the architect was trying to do) by seeing how it relates to nearby buildings.
For my current assignment I got as high as I could to accomplish this, about 90 feet up from street level. Not a bad view and sunset! The finished shot should be nice and help explain the subject building to its surroundings.
