Is anyone able to draw up a layout for the Web Planet Interior?

Wow that is a very roundel-less console room besides the door wall and interior doors.

Is it that the audience view is on the opposite wall to usual, the exterior doors being on the right? So the wall we're looking at in that pic is usually where the cameras are and the roundel wall we're used to is where the cameras are in this story?

Yep. One of the many wonderful, crazy innovations in this story. They didn't just 'break through the fourth wall', they showed it! 

This layout has always been fascinating to me - are there any floor plans available?
