SL Green Realty’s redevelopment project at One Madison Avenue will include 18 new floors and bring the building’s total rentable square footage to about 1.5 million square feet, according to new details released about the project on Monday.

The firm has tapped architecture firm Kohn Pedersen Fox to lead the redesign of the building, which will include modern office spaces, tenant floors and more than an acre of outdoor terraces.

SL Green is using 218,000 square feet of development rights to redevelop the building as-of-right. Demolition and construction should begin in 2020 or 2021 after the building’s existing tenant leases expire. The project will feature rentable floorplates of between 32,000 and 35,000 square feet.

The Real Deal previously reported over the summer that SL Green planned to use air rights to redevelop the tower as an office building after Credit Suisse’s lease expires in December 2020. At 1.1 million square feet, it is the largest tenant in the building.

SL Green Realty Corp., New York City’s largest office landlord, today detailed sweeping redevelopment plans for One Madison Avenue, the Class-A office tower next to Madison Square Park. A Kohn Pedersen Fox addition on top of a nine-story redeveloped podium will add modern office space, tenant specialty floors and over one acre of outdoor terraces, with design harmonious with the surrounding Madison Square district, complementing the Park by incorporating significant softscape features.

To advance the most ambitious adaptive-reuse project in the Midtown South submarket, SL Green has re-assembled the design and development team currently constructing the iconic One Vanderbilt – Kohn Pedersen Fox, Hines and Gensler – to undertake the project. Like SL Green’s One Vanderbilt Avenue project, One Madison occupies a full city block bounded by Madison and Park Avenues between 23rd and 24th Streets.

“One Madison Avenue has an unbeatable location overlooking Madison Square Park, and after the redevelopment it will become one of the most sought after addresses in all of New York City,” said Marc Holliday, Chief Executive Officer of SL Green. “To take on such a sophisticated project, we’ve gathered the team responsible for constructing the ahead-of-schedule, 1,401-foot-tall One Vanderbilt. I’m confident their expertise will help us successfully revitalize One Madison into an exclusive address for today’s leading companies.”

SL Green is redeveloping the building as-of-right, using 218,000 square feet of available development rights, which will increase the total rentable square footage of the building to nearly 1.5 million square feet. One Madison will be reduced to its existing ninth floor in order to create 18 additional new column-free floors above. Interior and exterior work to the existing podium, including revitalizing the lobby, modernizing core elements and activating retail space, a multi-purpose auditorium, and below-grade space, will create a complete, seamless, and unrivaled Class-A experience in Manhattan’s highest demand office district. Demolition and construction are expected to start in 2020/2021 following the expiration of existing tenant leases.

The newly-constructed tower will feature 32-35,000 rentable-square-foot floorplates, with 60-foot column-free clear spans and 14’-3”-foot floor-to-floor heights throughout. On the 10th and 11th floors, exceptional views of Madison Square Park are featured at panoramic terraces and specialty office floors, which will create an elegant and respectful transition from the masonry base to the new tower addition. Several private tenant terraces are also included at the top of the tower, all of which feature skyline views of the city.
