5/27 Looks like that overlay cladding is going in at the top. It's going to look really silly for a while.
It appears from the pics that the struts holding up the new curtain wall are attached to the structural framework and that the concrete panels, and thus the old window openings, will be removed as the work progress, increasing the light/space.I'm struggling to imagine how the interior is going to work with this. Are they just going to be very deep window wells with drywall/trim extending from the existing interior wall across the existing window well to the new curtain wall? Is the existing exterior envelope that inefficient that this is still feasible through heating and cooling cost savings? I don't see the point of going through all the trouble here if you're getting the same amount of light in the space..

So why not just remove them now like they did on the bottom levels?
DZH22: Do you happen to have older photos from the same vantage point/location, prior to the recladding? That might settle whether or not an additional level (mechanical) was added at the top. The tip of the lower One International Building makes for an excellent 'marker'.
