Whether it was SAS or not, it seems like it could have been a later addition whether it was days after things were approved or months into construction...
The blue shows that it just seems to stick out. Granted a greenhouse would do this no matter what, perhaps that extra brick structure that doesn't have the same height as the show building would not be needed if it was in the original plans and this really was the originally intended extended queue. The red shows how it's just extra space. Makes sense for an extended queue which seemed to be the reason for the addition. And the green shows how we could have just walked up steps and been at the same point. Keep in mind I'm majoring in music business, so if this doesn't make sense then bare with me.
