Hi Ann
I am not sure where you are based but if you can get into the NLI in Dublin City Centre they have the Thom's Official Directory of the United Kingdom of Great Britain and Ireland for the Year 1916 available to view in the Main Reading Room and in the Manuscripts Reading Room of the library. You need to be a member to access it but that is free and usually the card can be created without an appt. I know Thom's didn't contain a list of residents but it might have the name of the business at that address, which might get you further along in your search.

https://www.militaryarchives.ie/online-collections/military-service-pensions-collection-1916-1923The Free Genealogy Advisory Service in the National Archives have been really good before when I have asked for advise on how to go further with research and they are another stop you could try. You just fill in the questionnaire and email it in to them. You might be lucky and they might have an interest in 1916 and go that little extra mile for you.
Best of luck, sorry I could think of a specific directory that would be of use to you.
Regards
