Finally, the glass for the new western staircase bump-out makes its debut. There appear to be visible brackets between glass panels in the curtain wall, so this is quite recent – the aluminum frames have yet to be finished. The copper flashing up top is nice and fresh, and if the renders are any indication, the wood panels just below that will be finished with steel panels. Peer inside closely and you can see the outline of the new staircase and the metal railings on each landing.
Worth noting, there is a major difference between the approved drawings and the built product – notice that the bump-out is four floors. The renderings show five, it was expected to extend down to ground level. That bottom section with the Lowes Green Guard (polystyrene foam insulating boards) might still be finished with steel panels and decorative “Cornell Law School” lettering, given its width; but, can’t be sure at this point.
With the newly-enclosed loggia already finished, this $10.2 million renovation project is in the home stretch; although a January 2018 was initially planned, a March completion seems fairly likely.

The enclosure also looks to be about half as deep as the rendering, no longer deep enough for a side door to the exterior at ground level.
Yes, that looks to be the case. It’s probably not a problem from a building code perspective because it may not have affected the “habitable” interior square footage.
