550 Madison

As part of the 550 Madison Avenue project, Sponzilli installed the privately owned public open space spanning between 55th Street and 56th Street in midtown Manhattan.

The privately-owned public space and plaza includes a partially covering glass canopy of monumental proportions giving the space a unique atrium-like feel. Orange County Ironworks was the steel fabricator, and Gabriel Steel Erectors assembled the steel over the rectangular space that spans between East 55th and 56th Streets.

The custom granite plaza extends an entire NYC block with over 10,000 sq ft of large format granite stone selected to match the existing materials utilized in the building.

Within the plaza you will discover a dense garden…the only publicly accessible green space in the East Midtown district. The area is beautifully enhanced by dozens of 25’ specimen trees, a waterfall, extensive plantings, custom outdoor furniture, and common area seating, all installed by Sponzilli.

The project is a magnificent repurposing of a previously closed off passageway between 55th and 56th Streets and required specialized engineered soil and custom-designed irrigation systems to support the sustainable urban landscape project.
