About the Building

340 Madison Avenue is a large Class A office building occupying the full west side of Madison Avenue between East 43rd and East 44th Streets, directly across from Grand Central Terminal. The property combines substantial floor plates, a highly visible Midtown East location, modernized common areas, and a broad tenant amenity program designed for large corporate occupiers.

The building has undergone a major repositioning that includes a new lobby with approximately 18-foot ceilings, high-end finishes, new elevator cabs, curated artwork, and opportunities for tenant signage and dedicated reception areas. Large tenants may also have the ability to create a private lobby on East 44th Street with dedicated exterior and interior branding, direct access to the main lobby, and connection to the elevator banks.

Office floors are substantial, with many full-floor opportunities measuring approximately 40,000 square feet. These layouts can support a wide variety of workplace strategies, including dense open-plan environments, traditional perimeter-office layouts, law firm configurations, large conference centers, training rooms, wellness rooms, phone booths, and collaborative areas. Representative test fits show floors accommodating well over 100 employees while maintaining extensive meeting and support space.
A major feature of 340 Madison Avenue is its 10,000-square-foot second-floor amenity center. The facility includes lounge areas, conference rooms, multipurpose event space, phone and meditation rooms, quiet rooms, café-height seating, a self-service bar, showers, and flexible meeting areas. The space can be reconfigured for everyday use or larger tenant events.

The building also offers 24/7 tenant-controlled HVAC, an important feature for companies with extended operating hours. Additional workplace technology is available through RXR’s tenant platform, which can support mobile building access, visitor management, amenity reservations, workspace booking, air-quality monitoring, and occupancy analytics.

Its location is one of the property’s strongest advantages. Grand Central Terminal is directly nearby, providing access to the 4, 5, 6, 7, and S subway lines, Metro-North Railroad, and Long Island Rail Road service. Bryant Park, the New York Public Library, Fifth Avenue, Rockefeller Center, and numerous restaurants, hotels, and fitness options are also within walking distance.

For companies searching for large office space near Grand Central, 340 Madison Avenue offers expansive floor plates, private branding opportunities, modernized common areas, tenant-controlled HVAC, a substantial amenity center, and one of Midtown Manhattan’s most convenient transportation locations.
