The 7 Shocking Features of the $100 Million Redevelopment
The extensive renovation at 360 Park Avenue South was designed by A+I (Architecture Plus Information) to create a fluid, dynamic, and accessible premier workplace. The investment focused heavily on creating an experience that goes far beyond standard office space, incorporating hospitality-level design and a comprehensive amenity program.
1. The Dual-Lobby Experience and Redesigned Entries
The building now boasts dual lobbies, a critical element in solving accessibility issues and creating a more fluid streetscape experience. The redesigned entries were opened up to invite the cityscape into the building’s core, creating a dramatic, modern, yet respectful transition from the historic exterior to the contemporary interior. This includes a significant architectural effort to create a more dynamic presence on Park Avenue South.
2. The Premier Roof Deck and Outdoor Space
One of the most valuable additions to the building is the expansive outdoor space. The renovation included the creation of a massive 13,000-square-foot roof deck. This amenity provides tenants with a highly desirable feature for events, casual meetings, or simply a break from the office, offering panoramic views of the surrounding NoMad and Gramercy Park area.
3. The Underground Amenity Hub (The ‘Subterranean Social Club’)
The transformation strategically utilized underutilized below-grade spaces to create a comprehensive underground amenity hub. This area is designed to attract both pedestrians and tenants, acting as a social and functional center within the building. This hub includes the fitness center, tenant lounge, and other communal facilities, transforming a typically neglected space into a key selling point.
4. Cutting-Edge Modern Building Systems
A major portion of the $100 million investment went into infrastructure, including modernizing the building systems. This ensures the tower operates with high efficiency, providing state-of-the-art HVAC, air filtration, and technology infrastructure that meets the stringent demands of today’s tech and financial firms like Optiver, who require robust, reliable, and high-performance environments.
5. The Arrival of High-Profile Tenants: Ziff Davis and Optiver
The success of the renovation is clearly demonstrated by the caliber of new tenants signing major leases in 2025.
- Ziff Davis: The publisher and digital media company committed to a 23,038-square-foot office lease, with plans to move in following the renovation wrap-up.
- Optiver: The global electronic market maker also signed a 23,038-square-foot lease in May 2025.
6. The New Restaurant Anchor: SAGA
Further enhancing the building’s appeal as a destination, a new restaurant, SAGA, is set to open a substantial 7,000-square-foot space. The addition of a high-quality food and beverage option on the ground floor not only serves the building's tenants but also integrates the property more fully into the vibrant NoMad dining scene, contributing to the area's mixed-use appeal.
7. A Focus on Wellness and the 'Future of Work'
The entire repositioning strategy was centered on designing a workplace that supports the evolving needs for the future of work. The proximity to Madison Square Park, coupled with the internal amenities, positions 360 Park Avenue South as a wellness-focused environment. The emphasis on natural light, high-end finishes, and communal spaces creates a magnetic environment intended to draw employees back to the office by offering a superior experience to working from home.
The Strategic Importance in the NoMad/Midtown South Market
The revitalization of 360 Park Avenue South is a microcosm of the broader trend in New York City commercial real estate: the flight to quality. In a post-pandemic market, companies are willing to pay a premium for brand-new, amenity-rich, and technologically advanced office spaces in highly desirable neighborhoods.
The NoMad (North of Madison Square Park) district is a hub for creative, media, and technology firms. By investing over $100 million, Boston Properties has created a product that specifically caters to this demographic—a blend of classic New York architecture with the modern, flexible, and high-tech infrastructure that "new economy companies" demand. The building now stands as a premier example of how historic assets can be successfully adapted to thrive in the 2025 office market and beyond.
