Nikkei_Simmer's Stupid Questions #3 - WCIF - A Small World (256x256) with only 9 lots:

This isn't exactly what you wanted, I'm not aware of a world like the one you're looking for but maybe...Hylewood by Nilxis ? It has 15 lots. And I've never counted the lots in Amberville, by aaronrogers8i3, but it's my favorite small town. It's a tiny dessert town based on Amboy CA. Createaworldblog went down a long time ago but all of aaronrogers8i3 's stuff is archived here. Personal favorite of his is Mesa Grande because of it's immaculate performance on my machine but that town is at least the size of sunset valley.
