SL Green to Redevelop One Madison Avenue, Creating Midtown South’s Premier Office Tower

Building upon One Vanderbilt partnership, Kohn Pedersen Fox tapped to
lead redesign of office building overlooking Madison Square Park

SL Green Realty Corp. (NYSE:SLG), 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 has been a visionary developer to work with at One Vanderbilt,
so naturally we jumped at the chance to collaborate on the redesign of
One Madison — a dramatic transformation that will infuse a timeless New
York City property with a dynamic, inspiring workplace for the 21st
century,” said Doug Hocking, AIA, Design Principal, Kohn Pedersen Fox.

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.
