745,000 SF • RADSON DEVELOPMENT •LEED SILVER (TARGET)

495 Eleventh, a 48-story, 745,060 sf, 650’ high-rise mixed-use development, is a study in composition and juxtaposition resulting from its transitional location in Manhattan’s Hell‘s Kitchen neighborhood, straddling the established residential neighborhood to the north and the new Hudson Yards Neighborhood to the south. As a result, the project commands a significant prominence along the Manhattan skyline and visually functions as the “cartilage” that links these two distinctly different aesthetics.

The building contains a variety of program uses, including: ground floor retail: a second floor 24,500 gsf supermarket; 305,000 gsf of commercial space; a 20,000 gsf conference center; and a total of 348 affordable rental residential units (including 48 supportive units) located strategically across the building. This program is supported by three below-grade levels which include a full level allocated to NYPD special vehicle parking facility. The diversity in program uses has informed the building’s massing, conceived of as three distinct sections roughly corresponding to the program: a 10-story base including NYPD parking and commercial office space; an 8-story mid-rise consisting of public conference rooms and event space; and a 30-story residential tower consisting of both supportive and affordable housing rental units.

On an urban scale, the building fills a significant void in the current Manhattan skyline; its profile is thus distinctive but cognizant of being part of the overall skyline composition. The project’s use of multiple alternative energy sources — including wind turbines and a solar array for its tri-generation central energy plant, with their exposed steel support platforms — is expressed externally as the building’s crown.

The project’s materials respond to the aesthetics of the surrounding neighborhoods. In the base the utilization of glass is greater, as historically this is better suited to flexible commercial office space. In the tower, the opposite is true. In both cases, glazing is generally located on the southern portion of the building in respect of the Hudson Yards aesthetic. During the day, the visual solidity of the UHP concrete panels establishes the mass of building, in keeping with the masonry load-bearing walls of Hell’s Kitchen. The introduction of exposed steel members and accents throughout the project recall the metal accents (exposed steel lintels, fitch plates, etc.) of the site’s historic industrial uses. Their introduction here also supports alternative energy installations which allow the project to target LEED Silver and Enterprise Green Communities certification.
