Newly built as the crown jewel of the Hudson Square Properties portfolio, 555 Greenwich is a 22nd century office building in both vision and performance. It is New York City’s first entirely fossil-fuel-free commercial office building and one of only ten LEED Platinum Core & Shell projects in the state.
A benchmark for the future of work, 555 Greenwich elevates the environment, the community, and every individual workstyle. Its fully electrified, geothermally heated design delivers exceptional efficiency, using 40 percent less energy than typical Class A buildings. It exceeds New York City’s 2030 climate target by more than 45 percent and aligns with New York State’s 2050 carbon neutral goals. As one of the greenest office buildings in the country, it sets a new standard for sustainable development in Manhattan.
Seamlessly connected to 345 Hudson on multiple floors, 555 Greenwich creates expansive and flexible floor plates that are rare in Manhattan’s commercial landscape. Together, the two buildings form the heart of New York’s most amenitized office campus with a conference center, a town hall auditorium, and a rooftop terrace. This combination creates a next generation workplace that attracts tenants and redefines what an office can be.
Going beyond required building code, 555 Greenwich + 345 Hudson represents the next level of high-performing buildings and sets a new sustainability benchmark for New York City.
Sharing the block with 345 Hudson, 555 Greenwich forges connections between its diverse occupants with communal spaces filling the block.

Inspired by the world’s most productive and innovative companies, 555 Greenwich + 345 Hudson cultivates an ecosystem of spaces supporting your workforce’s shifting daily needs
