Yes, that's right.
Even when it wasn't, explosions would shake the foundation and so on... I don't want to exaggerate the importance of that, but I could see how it could intrude on a number of things.
There was one last question on that theme. What has been done so far with phase two of the visitor welcome centre, I suspect, must have had no input from the new process you've suggested. But is the intention to allow that process to kick in for any further decisions made on phase two of the visitor centre?
