BXP's tower at 343 Madison Avenue is visibly climbing, the New York Post reported — steel going up next to Grand Central on a site that's been talked about for years. For a GC or a trade contractor scanning Midtown East, that's the signal that matters: this one stopped being a rendering and started being a schedule.
343 Madison sits in the East Midtown rezoning district, the same regulatory zone that's been clearing the way for a wave of office towers to replace older stock near Grand Central — the same district the Chrysler Building's renovation and other recent East Midtown filings sit inside. A tower actually topping structural steel there is a different thing than another district filing; it's crane capacity, curtain wall, and MEP fit-out scope landing on the market now, not in a future cycle.
The Post's report didn't carry a square footage, a general contractor name, or a completion date — those specifics should surface as BXP files updates or as DOB permit activity catches up to the visible steel. Worth checking back against DOB permit records for the address as the structure tops out, the same way this desk has been tracking other East Midtown and Midtown South towers rising this month.
