633 Third Avenue | 1,347 RSF (Office Condo)

633 Third Avenue is a classic Grand Central Class A skyscraper on Third Avenue in Midtown East. Marketing materials describe approximately one million square feet of commercial space in a 41-story tower completed in 1962 to designs associated with Harrison and Abramovitz.

Floorplates are substantial: building profiles note large mid-building floors (including references to roughly 44,000+ rentable square feet on select levels) with smaller plates higher in the stack. That range lets users pursue full-floor identity or efficient multi-suite layouts depending on headcount.

Ownership and leasing materials from Time Equities emphasize modernization of the lobby and elevators, 24/7 access, and a classic postwar tower profile updated for contemporary office users. Those upgrades matter for first impressions and daily vertical circulation in a high-rise environment.

Location remains the leasing engine. The building sits in the Grand Central orbit with access to Metro-North, Grand Central Madison, subway lines serving East Midtown, and the dense hotel, dining, and professional-services ecosystem between Third Avenue and Park Avenue.

For tenants comparing large Grand Central towers, 633 Third Avenue offers scale, a known architectural lineage, and ongoing common-area investment. Contact Noah & Co. to review current availability, floor sizes, and how the building competes with other Third Avenue and Park Avenue options.
