The actual stage is 8.5x7.3M (28x24ft), with the outer being 10x12M (32.8x40ft). The outer truss cannot be any bigger without adding extra towers, therefore this determined the stage size as we thought that 4-6feet exclusion zone was the minimum needed with the amount of robots going OOTA these days. But saying that everything is modular, so there would be no problems adding to it.
