In one of the largest Brooklyn rental deals in a decade, global e-commerce website Etsy has signed a 10-year lease for the entire nine-story building at 117 Adams St. as well as the sixth floor in an adjacent building at 55 Prospect St.

The owner of both Dumbo properties is a partnership that includes Kushner Companies, Invesco Ltd., LIVWRK Holdings and RFR Realty. The partnership acquired the properties and several others last year from the Jehovah’s Witnesses for $325 million (NYLJ, Nov. 6, 2013).
