Thanks for a thorough answer.
I recommend to remove name, description and website from the building and add add office=research or office=company for the node.

You can do this at the bottom section "Tags" when you select the node or the building. 

You can also move the node closer to one of the staircase entrances or whatever entrance you are using. Just don't put it too close to the edge or those maps which want to display it, may have not room for the text.
