Central Hall Revisited

My 43rd blip, nearly 15 months ago, was of this building and I had started to make a collection taken from the same spot.

That project was interrupted by a move of building and a consequent change in my route to work, but I was back along the old route today and couldn't resist. Over the past few months, this spaceship of a building has been undergoing major structural repairs and a little cosmetic surgery too.
