More Skyspace details from Neil:

A couple of extra observations:

I was in there on Sunday. We had a really grim weekend with stacks of
rain, and the floor was all grimed up, plenty of mud and water in the
drainage channels. The roofhole /is/ open to the elements, and it’s
actually quite nice when it’s drizzling.

I hadn’t noticed them before, but there are lights installed on top
of the side-bench things. Significantly less ambient light on Sunday,
so they were visible although it’s only a slight glow. Can’t see
them, but I’d guess they’re fluorescent tubes and the light they give
off is slightly peachy. Maybe that’s just in contrast to the very-
white walls, though.
