I'm not sure how I forgot this before, but I just remembered that I neglected to describe Barlowe Manor XD. There are two: the home of Edmond's mother, Esmerelda, and the home of himself.
Esmerelda Barlowe's manor is probably one of the manors in the upper level of the Upper Plate. I don't think it has any distinguishing features to speak of, aside from maybe a gate and a large fountain or something like that, but this location probably won't even come up so I'm not sure it's necessary.
Edmond's manor, however, is shrouded in secrecy. So much so that nobody even knows where exactly he is (or if he even lives in one) but it is assumed as such due to his position. I would add more details but I'm not sure how to make this comment screenable so I'll leave it at that for now. We'll talk about it when you're online later~.
Anyway, sorry about that XD Hope this helps a bit!
