NEW YORK—LBi, a marketing and technology firm, has signed a 26,000-sq.-ft. lease expansion at 11 West 19th Street in the Chelsea-Flatiron District of Manhattan. The company will now occupy a total of 78,000 sq. ft. of space on multiple floors.

Bob Savitt of Savitt Partners negotiated the lease on behalf of the building ownership. Cushman & Wakefield brokerage professionals Jamie Katcher and Frank Coco advised LBi on its occupancy strategy and lease transaction.

The firm originally leased 52,000 sq. ft. of office space at the 11-story building in 2010.

“We have grown exponentially in both New York and across North America over the past two years,” said Judith Carr, president of LBi in the U.S. “As a result we required additional space to house our growing team of strategy, creative, media and technology experts within 11 West 19th Street.”

Built in 1902, 11 West 19th Street totals 280,000 sq. ft. of space and has recently been updated to include a new lobby, updated elevators and more. The property offers tenants 24/7 building access, a lobby attendant and on-site property management. Other tenants at the building include Time Warner, Nautica, Epsilon Interactive, VF Sportswear and Tory Burch, among others.
