I've got a huge space on my mainland just to the bottom right of resident services by the beach and I can't think of any ideas for fill it. My island has a loose foresty witchy theme but that's not super set in stone as I've got a few areas that don't really fit in with that. I could maybe spare a villager house to put in there, but I'm just stumped on what to put in there. What does everyone else do to fill big gaps?
