Kato International LLC has initiated a significant redevelopment program at Tower 49, its long-held office property at 12 E. 49th St. The owner is undertaking an owner-led repositioning that centers on adding amenities and integrating a large flex office platform into the existing tower. As part of the initiative, Kato is introducing two dedicated amenity floors and rolling out a building-wide tenant experience program.
The tenant experience platform will be managed by Industrious, which is also planning what is described as the world’s largest single flex office footprint within the property. The flex component is expected to span 18 floors and cover 291,600 square feet, creating a substantial block of flexible workspace within the existing office tower. This program is designed to operate across multiple contiguous floors, providing a scalable flex option for a range of occupiers.
Kato International has owned Tower 49, which totals 600,000 square feet, since 1986. Company leadership characterizes the current phase of work as a reaffirmation of its long-term commitment to both the asset and its tenant base. By deploying capital back into the building and aligning with specialized partners, Kato is seeking to elevate the workplace environment within the tower.
The redevelopment team for Tower 49 brings together several firms with expertise across design, branding, and hospitality. Alongside Industrious, participants include Bonetti Kozerski Architecture and MdeAS Architects, which are contributing to the architectural and interior vision for the property. Branding firm Mucca is involved in refining the building’s identity, while hospitality advisory firm Friend of Chef is engaged to support the amenity and service programming.
The Tower 49 redevelopment is slated for completion by the fourth quarter of 2026. Upon delivery, the building will feature enhanced shared spaces, a formalized tenant experience framework, and a sizable stack of flex office inventory managed under the Industrious platform. The combination of amenity expansion and flexible workspace is intended to reposition the tower’s offering while maintaining its existing office use.
