Why not approach them, and ask if it would be possible to be allowed in half an hour before they are due to open, to get pictures of the architecture, and to be able to do it in a way which won't impede any members of the public.
By doing that, you are showing that you are a) only taking pics of the building itself, as opposed to anything trademarked, such as company logo's b) trying to minimise the risk to the public, therefore reducing any liability on their part c) showing them courtesy by approaching them.
A little respect goes a long way.....
