733 Third Avenue
733 Third Avenue—also known as 11 Grand Central East—is a repositioned Midtown East office tower located at the corner of Third Avenue and East 45th Street, directly within the Grand Central corridor. This location places tenants in one of Manhattan’s most transit-centric business districts, offering immediate access to major subway lines, commuter rail, and the surrounding Midtown office ecosystem.
Originally constructed in the mid-twentieth century, the building has undergone a comprehensive modernization program that has redefined its presence in the market. Upgrades include a redesigned lobby, improved building systems, and a curated selection of prebuilt office installations tailored to modern tenant expectations. As a result, the property now competes effectively with newer Class A assets while maintaining more flexible pricing relative to trophy towers nearby.
The building rises over thirty stories and offers efficient, tenant-friendly floor plates that support a wide range of office layouts. Companies can implement traditional perimeter office configurations, collaborative open work environments, or hybrid layouts depending on operational needs. Large windows along multiple exposures provide consistent natural light, particularly on upper floors, enhancing the overall workplace experience.
733 Third Avenue appeals to a diverse tenant base, including financial services firms, legal practices, consulting groups, and growing companies seeking proximity to Grand Central without committing to premium Park Avenue rents. Its positioning makes it especially attractive for businesses with regional employees, as commuting via Metro-North, the Long Island Rail Road, and multiple subway lines is both convenient and reliable.
From a strategic leasing perspective, the building offers a balance of location, efficiency, and modernized infrastructure. Tenants benefit from a recognizable Midtown East address, upgraded common areas, and the ability to secure high-quality space in a competitive pricing band.
For companies evaluating office space in Manhattan, 733 Third Avenue stands out as a strong Grand Central option—delivering accessibility, flexibility, and updated office environments within one of the city’s most established and transit-oriented business corridors.
Technical Specifications
733 Third Avenue is a large-scale Midtown East office tower engineered for multi-tenant occupancy with efficient layouts and modernized infrastructure following its repositioning. From a technical and operational standpoint, the building offers the following key specifications:
The structure rises approximately thirty to thirty-two stories above grade, reaching an estimated height of roughly four hundred to four hundred twenty feet to the roof. This gives the building a strong vertical presence within the Grand Central skyline while maintaining efficient floor-to-floor stacking.
Total building size is approximately six hundred thousand square feet, making it a significant office asset within the Midtown East submarket. This scale allows for a wide tenant mix, from smaller prebuilt suites to full-floor users.
Typical office floor plates are generally in the range of eighteen thousand to twenty-five thousand square feet. These plates are considered highly efficient, supporting both dense workstation planning and perimeter-heavy office configurations with interior conference rooms and collaboration areas.
The building is constructed with a steel frame and reinforced concrete system, enabling relatively wide spans and flexible planning across floors. Column spacing supports clean layouts, minimizing inefficiencies and allowing for modern office design.
Ceiling heights are within standard commercial office ranges, with upgraded prebuilt installations in many suites allowing for contemporary finishes, including exposed ceilings and modern lighting where applicable.
Vertical transportation is handled through multiple passenger elevator banks serving the office floors, along with dedicated freight elevators. Elevator zoning improves traffic flow and supports the building’s multi-tenant structure.
Mechanically, the property is equipped with a centralized HVAC system designed for multi-tenant use, with distribution adaptable to individual suite configurations. Electrical systems support a wide range of office users, including technology, financial, and professional services firms.
The building features frontage along Third Avenue with additional exposure along East 45th Street, providing strong window lines on multiple sides. Upper floors benefit from enhanced natural light and open exposures toward Midtown East and the East River.
From a classification standpoint, 733 Third Avenue is considered a Class A office building following its repositioning and capital improvements. It competes by offering modernized infrastructure, efficient layouts, and prime transit proximity rather than new construction pricing.
Overall, the technical profile of 733 Third Avenue supports a broad range of tenant requirements, combining scale, efficiency, and upgraded systems in one of Manhattan’s most transit-accessible office locations.
