Renovations at this New York City and National Historic Landmark in midtown Manhattan enable the library to provide a greater range of public facing-programs, exhibitions, and amenities, augment research facilities, and improve logistics and services for its many constituents as the building continues into its second century. BBB worked in collaboration with Mecanoo on the Midtown Campus Renovation, which includes renovation and expansion of the Stavros Niarchos Foundation Library (SNFL) across Fifth Avenue.
New York Public Library, Stephen A. Schwarzman Building
New York, NY

Reimagining the New York Public Library’s Midtown Campus includes renovation of the historic and iconic Stephen A. Schwarzman Building, the Library’s flagship research facility.

Enhancements include the Marshall Rose Plaza, a new public entrance and terrace, new exhibition, retail, and café functions, as well as the addition of vertical circulation and upgraded building systems, all in deference to the building’s original Beaux-Arts design.





Modernizing a Landmark

A Fifth Avenue Campus
Rethinking the two-building NYPL Midtown campus, BBB's plan consolidated all circulating materials at the Stavros Niarchos Foundation Library (formerly the Mid-Manhattan branch) and refocused the Stephen A. Schwarzman Building around research and exhibitions.

A New, Accessible Entrance
After lowering an existing electrical room on 40th Street, the space above was transformed into the Marshall Rose Plaza, a 2,250-square-foot public space with a new, ADA-accessible bronze-and-glass doorway and marble cladding sourced from the same Vermont quarry as in 1911.

Room to Move
With new exhibition space elsewhere, the Library could remove outdated displays that crowded the corridor overlooking Astor Hall. Historically sensitive ceiling lamps and seating were reconstructed, and contemporary glass parapets meet current safety requirements.

Sustainable Energy
The project included the replacement of aging, inefficient mechanical equipment with new, more efficient systems, yielding an estimated 30% reduction in Energy Use Intensity (EUI) and long-term operational cost savings.

Beyer Blinder Belle
Other spaces formerly serving back-of-house uses are restored for public use, including the Center for Research in the Humanities, dedicated to research and scholarly work.
