[Cohen, Gerald Leonard]

I've just received the media inquiry below and don't have an answer.
Would someone on our listserv perhaps have a suggestion?

Sir,
 
I write for a legal publication and have a question on the origin of the term “Law Offices of ….”. Why is it always law officeS, the plural? What if it is just one room? Wouldn’t that make it a law office? A lot of solo attorneys advertise as having Law Offices, and I imagine them going back and forth between dimly lit rooms to read legal texts and ponder deeply. I’m wondering if there is a story behind that plural form?
