Inside 620 Avenue of the America's: What’s Really Happening with Chelsea’s Historic Megasite?
By Robert Thorne
Upper-floor office space along 6th Avenue faces a very different challenge than street-level storefronts. The building’s floorplates run between 110,000 and 125,000 square feet each. These dimensions attract specific enterprise tenants but sit entirely outside the sweet spot for conventional mid-sized office leases.

|---|---|---|---|
| Primary Tenant Profile | Siegel-Cooper "Big Store" | Bed Bath & Beyond, TJ Maxx | Segmented retail, institutional offices |
| Floorplate Division | Unified multi-level department store | Single-tenant mega blocks | Subdivided creative suites & retail bays |

Upper-floor spaces feature ceiling heights topping 15 feet alongside open sightlines supported by historic cast-iron and steel columns. These structural realities continue to draw media organizations, software developers, and engineering firms that require sprawling single-floor collaborative layouts. Yet the competition remains sharp: newer Hudson Yards constructions and redeveloped Midtown South properties are aggressively vying for the same corporate rosters.
