According to Savanna, Twitter, Inc. has leased 140,928 s/f at 245 and 249 West 17th St. in Chelsea. The transaction caps a remarkable transformation of the turn-of-the-century buildings that Savanna purchased in November 2012 and re-launched in November 2013 following a $21 million capital overhaul. Built in 1902 as the original wagon and warehouse for the Siegel Cooper Company, 249 West 17th St. has retained its loft-like qualities that exhibit 14-17 ft. ceiling heights, 35 ft. column spans and 9 ft. windows. The landlord was represented by the team of David Falk, Peter Shimkin, Danny Levine and Nick Berger of Newmark Grubb Knight Frank, as well as William Stempel and Amy Fridman of McDermott Will & Emery. Twitter was represented by Mac Horner, Andy Poppink, Clayton Kline, Derek Johnson and Reid Longley of Jones Lang LaSalle. "The vision that ownership had for the project was to provide a sharp, high end renovation that would meet the image and lifestyle of a growing, progressive company," said David Falk, President, New York Tri-State Region for Newmark Grubb Knight Frank. "Twitter is exactly the type of exciting company we envisioned to call 17th Street home."
