Blackstone is expanding its New York City headquarters at 345 Park Avenue. The giant signed a seven-year lease for an additional 149,000 square feet of Midtown Manhattan office space here, according to the owner, Rudin Management.

The 1.9 million-square-foot, 44-story building at 345 Park Avenue boasts a LEED Gold Certification. Blackstone has been a tenant in the office tower since 1988. With this deal, the company brings its occupancy here to 575,000 square feet across 16 floors. It will be taking over the space Deutsche Bank’s DWS Group will vacate in 2019.

Neil Goldmacher of NKF represented Blackstone in the deal, while Rudin’s Tom Keating acted on behalf of the owner. The asking rent for the space was $125 per square foot, as reported by The Real Deal. Other tenants in the building include auditors KPMG, the National Football League and Loeb & Loeb LLP.
