I have one. It is set up in a straight line: autoloader, imager, bridge, processor, stacker. It is 25' long and 80" wide at the widest point. I have 36" clearance on the back side and 7' clearance on the front side (pretty much what you need to be able to get the cassette dolly in and out of position). The autoloader end needs probably no more than 36" just so you can get around the machine. Then whatever you feel you need to move the stacker dolly -- my room is wide open on that end so it is really up to what space you have. Thought I may have had a drawing but it has been a long time and I cannot find it. Hope that helps!
