A room with a view

The view from my classroom. I found out today why we never see the workers - they do it at night, and then get the big crane to lift out the rubble in the early hours of the morning when there aren't many shoppers about.
I'm not allowed to go any closer to the hole, not even with a hard hat from PoundLand.
And some people have said we are getting a swimming pool, but I think it might be dungeons. We do 'Games Development'; I guess those guys could be down there playing dungeons and dragons, they don't need daylight, and no one would miss them.
