The plan for that block was to demolish the Concourse too (but save the lobby and restore the facade of the rest of the building by grafting it onto a new structure). So no new tower is being built anytime soon if they are restoring the Concourse.
I can see how they would want to tear down that 4 or 5 story building to the west of the Concourse though. Ever since Winstons closed some years ago, its been empty.
The Concourse Building seems to have avoided death thanks to the lack of demand for office space in the last few years. I guess that's one positive aspect of the higher office vacancy rates we've been seeing. It still boggles the mind that it was even being considered for demolition.
Noticed this morning that things are getting more advanced; the terra cotta facing atop the SE corner of the Concourse was removed.
Again, can't tell whether it's for "restoration" or "reconstruction". (Or maybe for some horrible foot-in-the-door in-between status where a denuded-for-safety's-sake Concourse makes do until demolition time...)
