Two active megaprojects define Midtown’s current construction cycle. BXP’s 343 Madison Avenue, a 49-story, 844-foot office tower designed by Kohn Pedersen Fox, broke ground at the former MTA headquarters site between East 44th and 45th Streets.
A few blocks south, JPMorgan Chase’s headquarters at 270 Park Avenue already opened to its first employees in August 2025. The $3 billion, 60-story supertall delivered 2.5 million square feet across a full city block bounded by Park and Madison Avenues, with capacity for 14,000 employees.
That’s not all! Four towers, four different construction phases, all within roughly six city blocks of Midtown East. That kind of clustering changes how an estimator has to think about logistics. Material staging, crane scheduling, and sidewalk shed permitting all compete for the same narrow stretch of curb space around Park and Madison Avenues. Pricing for those line items reflects it.
