an old building<,> filled with rubbish (comma usage)

[Euphoria.]

Hello everyone,

I saw the sentence below in a coursebook.

Opposite Elsie's bar is an old building, filled with rubbish.

I am wondering why they use comma there. I wouldn't use comma if I was writing such a sentence. Is the comma there necessary? Can I omit it if possible?

Thank you.

It's optional, I think.

I think people who study English sometimes don't realize that comma usage in English is very often a matter of opinion, or of style. Certainly there are some rules that everyone obeys, but in many cases (such as this one), it's up to the writer. In the case of commas, it may have to do with how writers would read the sentence aloud. If they think there would be a pause, they will probably use a comma.
