The visitor welcome centre is the area where almost all of my concerns are focused.
When it comes to issues like putting elevator shafts into the current courtyard areas in the Centre Block, on its face, I think that makes sense, and so on.
My concerns are entirely around the visitor welcome centre and its colossal size. It really is big. It's going to be very expensive. It's bedrock down there. I don't know if it's granite, sandstone or limestone.
Does anybody else know?
