ABOUT GRAMERCY PARK

Technology firms have driven job growth in New York City over the past decade, and as a result, TAMI (Technology, Advertising, Media and Information) tenants have been the backbone of New York's robust leasing activity over that span. Gramercy Park, like other areas in Midtown South, has been a major beneficiary of this tech expansion.

Companies such as Pitchbook and Netflix have been among the largest space-takers of late, while Facebook's ceaseless appetite for expansion has thus far been a boon. The area has seen coworking companies take full advantage as well by opening locations in the area in hopes of capturing existing tenants who are experiencing growth but still wish to remain in the neighborhood.

In addition to quality office buildings, the neighborhood contains scenic parks, retail shopping, and quality restaurants.
