HNTB Leases 3 Full Tower Floors Totaling 78,000 Square Feet At ESRT’s Empire State Building

HNTB Corporation has leased three full floors, totaling more than 78,000 square feet, at the Empire State Building, announced landlord Empire State Realty Trust, Inc. (NYSE: ESRT).

The tenant, recently named one of the 10 Most Innovative Companies for 2015 by Fast Company, will be relocating its New York office, taking occupancy of floors 56-58 in the fourth quarter of this year.

“We have terrific momentum in leasing at the Empire State Building, and while HNTB’s lease reduces our current inventory to two full floors, we will be delivering to the market two full floors in 2015,” said Thomas P. Durels, Executive Vice President, and Director of Leasing and Operations for ESRT. “The terrific response to our unique urban campus’s new amenities and improving neighborhood is the fruit of our team’s hard work, and we look forward to more leasing.”
