Empire State Realty Trust Signs Full-Floor Lease With COOKFOX Architects

NEW YORK CITY, October 14, 2015 – Empire State Realty Trust, Inc. (NYSE:ESRT) has just added the headquarters of COOKFOX Architects to its tenant roster at 250 West 57th Street.

The lease with COOKFOX occurs on the eve of ESRT’s announcement that the 26-story, 527,627-square-foot office building will undergo renovations that include a new lobby, new elevator cabs and new retail storefronts. Work is scheduled to begin in early 2016.

“We’re delighted to welcome COOKFOX as a full-floor tenant,” said Thomas P. Durels, Executive Vice President, Director of Leasing & Operations, for ESRT.

Mr. Durels noted, “Our new lobby and efficient floor plates with an abundance of natural light will appeal to larger users. We are consolidating five full floors that range from 12,000 to 27,000 square feet and will be made available for the first time.”

The property is located along Billionaire’s Row, with easy access to public transportation, and cultural icons such as Central Park, Columbus Circle and Carnegie Hall.

COOKFOX’s new 20,000-square-foot headquarters will occupy the entire 17th floor.

“We are grateful to have CBRE and ESRT as partners to secure and design a new studio that will explore the next generation of a high-performance, healthy workplace,” added Richard A. Cook, Partner of COOKFOX Architects.

COOKFOX is known for its LEED Platinum projects in New York City, including the Bank of America Tower at One Bryant Park (the world’s first LEED Platinum commercial skyscraper) and the build-out for Skanska Construction’s North American headquarters at the Empire State Building (another ESRT property).

Mary Ann Tighe, Gerry Miovski, Brendan Herlihy, and Arkady Smolyansky of CBRE represented COOKFOX in the lease negotiations. ESRT was represented in-house by Keith A. Cody, along with Harry Blair, Sean Kearns and James Schunk of Cushman & Wakefield.

“In a move that combines rental cost savings, as well as spectacular space design that matches their own high standards, COOKFOX is moving from Ladies Mile to Billionaires Row,” said Ms. Tighe, CEO of the New York Tri-State Region, CBRE. “Their new home will not only have more space and light, but also outdoor terraces on the east and west of the building that will accommodate COOKFOX’s commitment to the environment as evidenced by their extensive plantings and beehive to produce their own honey.”
