Completed in 2008 through a transformative $72 million redevelopment by the acclaimed firm Moed de Armas and Shannon (MdeAS), 100 Park Avenue seamlessly blends timeless corporate functionality with cutting-edge, LEED Gold-certified office space.

Located just a block from Grand Central Terminal, the building features a striking new metal and glass façade, a grand two-story atrium lobby, and upgraded elevator cabs. Significant enhancements to the infrastructure—including a modern cooling plant, increased electrical capacity, and a sophisticated security system—further elevate its appeal.

One of the pioneers in SL Green’s New York portfolio to embrace sustainability, 100 Park Avenue includes green roofs and has implemented recycling and energy conservation initiatives, resulting in a notable reduction in its carbon footprint.

The property’s excellence has not gone unnoticed; it received the prestigious “International Building of the Year” award from the Building Owners and Managers Association (BOMA).

Originally constructed in 1949, 100 Park Avenue was among the first new office towers to rise south of Grand Central Terminal during the postwar boom. MdeAS’ redesign introduces a sleek glass curtain wall along Park Avenue, complemented by aluminum composite panels that create a vibrant presence while honoring the building’s original proportions and setbacks, ensuring expansive views.

Remarkably, the building remained fully occupied throughout the renovation, affirming its status as one of Midtown’s most sought-after locations. Beyond its prime address—just a block from Grand Central’s transportation hub—it offers easy access to the New York Public Library and Bryant Park, enhancing its appeal for businesses and visitors alike.

Grand Central Station office space average price for rent: Class A $75-90 per square foot.
