Constructing Unique Living Space

I often wonder where inspiration and creativity come from especially while creating new levels. Currently I'm working on my Battle of the Bodies Mod inside a temple where people worship 4 elements. One of the best ways I fill out the levels of a place where people are living is to think it out logically: make a place for the worshipers to sleep, make a place where supplies are stored like food, make perhaps an area where trash is dumped because taking it all the way through the dungeon would take a long time, where would the boss stay, what sort of things would the boss need on a day to day basis (some robes, a night stand, a personal chest, a bed, maybe a divider between his personal stuff and the rest of the NPCs). Of course, there are no bathrooms in the world of Oblivion but maybe place a chamber pot somewhere. I would think that maybe there's a prep room before entering naturally dangerous areas that the worshipers need.
