Is this a possible mechanic?

I had a bit of a strange question..
So, if I built a giant map and placed small areas where a player house could go, would it be possible to script building a house and having one player on the whole server control that house until they die, sell it, or is that not possible?
I feel like spawning m2s is one thing, but this seems like it would have to be instanced, or something. Like, hide the area behind an obscuring wall.
Just a forethought on my upcoming world map, I really hope to add player housing to it if possible.

maybe look into eluna lua engine.
