What was left?

It had been a couple of weeks since the panels were removed. The crowds were all gone, but it felt that it was a long time ago that the works were done. I realised this while climbing up to my clinic using the stairs yesterday. It was replaced by some plywood.

I wonder if they would replaced it soon with some permanent glass panel. I would wonder then how long before the fungus would would appearing. What would it looked this time?
