Across from one of the most talked-about new towers in New York City, another transformation is quietly taking shape. At 383 Madison Avenue, union contractors and carpenters with the New York City District Council of Carpenters are carrying out a comprehensive $1 billion renovation of JPMorgan Chase’s investment banking headquarters—while the 47-story, 1.2 million-square-foot building remains fully operational.
The scope spans interior office systems, acoustical and ceiling installations, architectural woodwork, specialty installations, and the scaffolding supporting the ongoing façade replacement. Every phase requires precise sequencing and coordination, as construction advances floor by floor without interrupting daily operations inside a global financial institution.
The modernization will introduce upgraded interiors, collaborative workspaces, and a reimagined lobby experience. When complete, 383 Madison will complement JPMorgan’s new headquarters at 270 Park Avenue directly across the street, forming a cohesive Midtown campus built with precision, coordination, and expert craftsmanship.
This is complex construction delivered in real time—where safety standards, quality workmanship, accountable performance, and ready access to skilled labor define the outcome.
