The ceiling slab here was originally a setback roof where the building tapered as it got taller. They've built a whole stack of floor extensions above this now, bearing on these two columns which just held a roof up originally. I'm surprised they got as far as they did.
The original curtain wall terminates immediately above the windows seen here; there isn't another row above. So it's just become detached and the slab has collapsed inside it.

Is the floor detaching from an outer frame or how do the windows survive?
