SL Green Realty Corp announced that Infor, a provider of business application software serving more than 70,000 customers, has signed a long-term expansion lease more than doubling its size at 635-641 Avenue of the Americas.
Infor’s expansion of 49,246 s/f covers 47% of the 635 building and increases its commitment at the combined buildings to 92,246 s/f.
“The market reaction to the revolutionary user experience we have built with our Hook & Loop creative team in New York has been overwhelming,” said Charles Phillips, CEO of Infor.

“Just over a year after moving into our Manhattan headquarters, the number of customer visits to our HQ is up 20 times over our previous location in
Alpharetta, and we are more than doubling our size to accommodate significant growth in this area of our business.”
The buildings were originally constructed in 1902 as one of the great department stores along the historic Ladies Mile” and subsequently divided and operated as two separate buildings.
SL Green is currently performing a building-wide redevelopment to re-combine the buildings. The work includes a new enlarged lobby, relocation of elevator shafts, new windows, restoration of historic façade and new storefronts, complete replacement of infrastructure serving the 635 building, construction of a new 10,000 s/f glass penthouse with 15 ft. ceilings and surrounding terrace together with a new rooftop deck with bocce court and landscaping available for use as entertainment space by all building tenants.
“We were delighted to work with Infor to meet their expansion needs and are very excited about the unique re-development of these beautiful buildings,” said Steven Durels, SL Green’s executive vice president and director of leasing and real property, who added “the building is a rare jewel within one of Manhattan’s most desirable neighborhoods.”
635-641 Avenue of the Americas is located between 19th and 20th Streets in Manhattan’s Midtown South submarket. The area is known for its large concentration of Internet, technology and new media companies.
