One Madison Avenue Tops Out

Today, KPF and SL Green celebrate the milestone for the renovation project, an office building overlooking Madison Square Park.

On track for completion in November 2023, KPF’s design for the project updates an existing, mid-century podium, retaining 67% of the building’s original structure, and adds an elegant new tower. The redesign is forecast to result in an energy reduction of over 60% against the AIA 2030 Commitment baseline. One Madison Avenue is currently 55% leased, drawing interest from leading tech and investment firms seeking Class-A office space in the heart of the city.

“We are especially proud of the design for One Madison Avenue, a creative repositioning project that complements the neighboring historic clock tower and integrates over an acre of outdoor space with exceptional views of Madison Square Park. We are thrilled to see it come to fruition as we commemorate the topping out,” said KPF Managing Principal Lloyd Sigal. “We have a long, successful relationship with SL Green and are excited for this latest collaboration that will redefine the Midtown South neighborhood and raise the bar for office space for decades to come.”

“With the success of One Vanderbilt, we proved that fully integrating hospitality and amenity into every corner of the building is an approach that works,” said Marc Holliday, Chairman and CEO of SL Green. “Combined with its incredible rooftop venue, private dining, tenant lounge and world-class health and wellness facilities, One Madison Avenue represents leading edge curation of experiences that fundamentally redefine the workplace.”

KPF’s previous renovation projects in New York include Hudson Commons, winner of the ULI Award of Excellence in Office Development, and current projects include 660 Fifth Avenue, where Australian financial-services company Macquarie Group has signed on as the anchor tenant.
