It’s around the subject, we already had a subject: the building. To be around themselves they would need to change the subject. Even given your example it’s not true, vicinity needs scale. The moon is around my vicinity if we use a stellar scale and there’s certainly a skyscraper closer to them than the moon.

That’s heavily dependent on era, size, region and quite honestly actual location in the building as well as height. Lots of early steel framed skyscrapers had traditional masonry lower stories that were wider than the steel framed core.
