I'd go with alba & joe. I'm no expert but the use of the words buildings and surgeries at the very least confuses the issue for me, and makes it all sound plural despite the "neither" start to the sentence.
"Neither A nor B", I can cope with, "Neither As", isn't 'nice'.
If you translate the problem into other languages, it gets easier, since the word "neither " always appears as a singular. It is singular in English, so requires a singular verb.
Try "Neither he nor she . . ." and you will see that the verb applies to one not both . " Neither he not she has any idea . . Neither he nor she wants to go to the party . . ."
