Photoshop. Create what you need the camera to see, cut to / from it seamlessly and you're there.
A fake hole, aka just having a piece of wood or something near the ceiling could possibly work.
You lost me on this part
"A hole in the ceiling would be at a staircase, or a office ceiling with plates you can remove to service the electricity and airconditioning.
A hole in the floor would be a staircase, or just a 1 or 2 or 3 step stairs."
I'm not really sure what you mean by it.. I need to be facing an elevator and usually stairways are off to the side down a hallway or something.
Sorry: trying to keep it short, but that doesn't work
You need a fake hole or a real 'hole': the real holes are often staircases, high thresholds like short stairs or ceilings with hatches or plates like this:

In Photoshop you can create visual elements to use in Premiere of AE.
It might work, but the perspective of the floor and ceiling might be off.
(The only way to find out is testing it.)
I saw a tutorial teaching this exact thing on Youtube. I went through and couldn't find it. It was using After Effects. Not sure if this helps, but it does exist.
Ahh okay. What you're describing is called a "drop ceiling"

I could do this effect for you. Just shoot the shots without moving the camera from its position and it can be done with different masking and motion effects (maybe a small amount of CGI, depending on what you're going for) nothing complicated.

since in the shots the perspective changes radically from 'frog view' to 'bird view',
Sean, do you have an example of the type of shot you're looking for? Is it something like the first ten seconds in this video?
