Question What would be the best way to generate an infinite array of rooms?

I'm making a game that requires an infinite array a rooms to navigate in. I've tried multiple ways to do it, but none of them have worked, and I'm out of ideas. I've been using a prefab to generate the rooms. There's probably an obvious way to generate the rooms, I'm just new to this.

 

As you approach the border between rooms, instantiate a new object from the prefab. As rooms go out of view, destroy them.
