Blackstone’s Park Ave HQ Footprint Increases to 1.06M-SF

A recent agreement at 345 Park Avenue will keep Blackstone’s headquarters at the building through 2034. As part of the 6-year extension deal, the money manager will expand by about 250,000 square feet, bringing the company’s total footprint to 1.06 million square feet. A tenant at the building since leasing 70,000 square feet in 1988, continued expansion over the years has established Blackstone as the anchor tenant of the nearly 2 million-square-foot tower. Although not verified, the deal is expected to include efforts by the landlord to “expand and enhance the facilities with amenities such as a fitness center.” The financial terms of the agreement were not disclosed.
