The Rudin Family announced that two tenants have signed new leases totaling 16,247 s/f at 55 Broad Street, its 30-story, 425,000 s/f office tower in Lower Manhattan.
Architectural services firm Curtis + Ginsberg Architects LLP has signed a 10-year, 10,307 s/f lease covering a portion of the building’s 8th floor.
The firm, which specializes in sustainable design, expects to relocate from 299 Broadway in Tribeca to 55 Broad Street by the end of 2019.
Rudin has also completed a 5,940 s/f lease on a portion of the 13th floor with online gambling operator Unibet Interactive, Inc., which will use the space to establish its first permanent office in the United States.
The transactions follow the completion of Rudin’s multi-million dollar lobby renovation earlier this year.
A full replacement and modernization of the tower’s elevators is set to commence later this year.
“We are pleased to welcome Curtis + Ginsberg and Unibet Interactive to 55 Broad Street,” said Michael Rudin, Senior Vice President at Rudin Management Company.

“Their commitments reflect Lower Manhattan’s continued appeal to creative, tech-focused companies and further validate our efforts to create and maintain a best-in-class work environment at 55 Broad Street.”
Curtis + Ginsberg Architects LLP was represented by Ruth Colp-Haber of Wharton Property Advisors, Inc., while Unibet Interactive Inc. was represented by Michael Baraldi and Lexie Perticone of Cushman & Wakefield. Building ownership was represented by Kevin Daly at Rudin Management Company.
Developed by the Rudin Family in the early 1960s and designed by Emery Roth & Sons, 55 Broad Street has long been regarded as one of the most significant smart buildings in the history of Lower Manhattan. The building was originally designed as the headquarters for Goldman Sachs.
In the early 1990s, the Rudins re-engineered 55 Broad Street, which earned the distinction as New York City’s first fully wired office building.
Current tenants benefit from a state-of-the-art workplace that includes fixed wireless accessibility, single and multi-mode fiber optics, high speed category 5 copper wire and a wide range of video conferencing and internet access capabilities. The tower is designated Wired Certified Platinum for best-in-class connectivity.
