The tallest building on our year-end construction countdown is JPMorgan Chase‘s 1,388-foot supertall headquarters at 270 Park Avenue in Midtown East. Designed by Lord Norman Foster of Foster + Partners with Adamsom Associates as the architect of record and developed by Tishman Speyer, the 60-story skyscraper will yield 2.5 million square feet of office space with a capacity of 15,000 employees, and will become the tallest structure in New York completely powered by hydroelectric energy. AECOM Tishman is the general contractor for the full-block property, which is bound by East 48th Street to the north, East 47th Street to the south, Park Avenue to the east, and Madison Avenue to the west.
Crews have begun to erect the fifth and final tier since our last update in late November, when project leaders and officials gathered to celebrate the completion of the final habitable floor in the fourth tier. Recent photos show the first beams in place for the culminating element of the crown, which is the smallest in height and volume and will house mechanical equipment such as the R&R Companies-supplied BMUs, some of which were already installed on the lower setbacks back in September. YIMBY predicts 270 Park Avenue’s architectural topping out will occur around the end of January.
The below photos were taken just before work on the fifth tier began to unfold.
Close-up photographs show the circular floor plate for the upper conference room at the top of the fourth tier. Office amenities will reportedly include a health and wellness center with yoga, cycling, medical services, and meditation spaces.
Installation of the glass and bronze-hued metal curtain wall has continued to progress, and now covers the superstructure up to the halfway point.
Additional work has also occurred on the framework for the glass walls that will enclose the 80-foot-tall cantilevering base, with new beams installed between the massive fanning columns.
Several of the base columns are in the process of being enclosed in metal panels around the eastern corner of the building. Additional components were seen along East 48th Street in preparation for further finishing work.

The second rendering gives us a full perspective of 270 Park Avenue looking north.
Over 300 Local 40 ironworkers are helping to assemble the steel-framed superstructure, along with crane operators and several hundred electrical, plumbing, and mechanical engineers. There will be over 8,000 jobs created by the end of construction, spanning 40 local unions and producing $2.6 billion of economic activity for New York City. A study by Deloitte shows JPMorgan Chase annually contributing $29.8 billion to the city’s economy, stimulating an additional 40,000 jobs across local industries.
Other teams contributing to the project include MEP engineer JB&B; steelwork supplier Banker Steel, which is manufacturing 93,600 tons of recycled steel; steel subcontractor NYC Constructors; structural foundation designer Mueser Rutledge Consulting Engineers; structural engineer Severud Associates; hoisting and scaffolding provider Safway Atlantic by BrandSafway Scaffolding Systems; and curtain wall supplier New Hudson Façades.
270 Park Avenue is the first development under the 2017 Midtown East Rezoning plan, which paved the way for taller commercial projects along this transit-centric corridor. The development will also introduce public outdoor space on the ground level of Park and Madison Avenues, wider sidewalks, and a large landscaped public plaza on Madison Avenue with natural green space and plentiful seating.
270 Park Avenue is anticipated to be completed sometime in 2025.
