It's likely all mechanical in there, so spandrel is to be expected. Just make it nice spandrel!
Vision glass allows too much heat through as you can't insulate behind it, and it wouldn't look any better. It will be spandrel or cladding, 100%It'll be the same shitty spandrel they've used everywhere else on this tower. As such, I've lost hope on this one. If the rationale is "because mechanical is behind it," that's a really stupid reason to aesthetically ruin a tower that is extremely prominent in the skyline. I'd rather it be vision glass and see the mech stuff than some garbage spandrel.
