In June, the rapidly growing product development social network Quirky inked a deal for 27,500 square feet at 601 West 27th Street, a former ministorage facility currently in the process of converting into offices for a number of other tech companies. Otherwise known as the Terminal Warehouse Building, the seven-story, 1.2 million-square-foot property near 11th Avenue was built in the late 19th Century, yet only just began leasing space to office tenants several years ago. As such, Quirky, which quadruples in size from its current space at 628 Broadway, took advantage of raw space, high ceilings and start-up friendly, loft-like floor plates. After the jump, Ben Kaufman, the company’s 25-year-old founder and chief executive and Greg Taubin, a senior managing director at the real estate firm Studley who inked the deal, reviewed the floor plan and discussed what impressed them the most.
