Hey, I provided the file for beginners so that nobody would have to set up anything since this exercise is only about modeling.  Creating this effect isn’t a necessary part of the exercise. It sounds like you followed all of the steps though and I don’t think there is any other magic. 

Here’s a default cube with the faces flipped and backface culling turned on in solid view:

Then to get the effect in rendered view, the faces near the camera are separated and camera ray visibility is disabled. I added a light so you can see inside, but cutting a window or something would work equally well:

I’m not sure what you mean by the cubical room not rendering. Perhaps camera ray visibility got unchecked on both parts instead of just the front part?
