Rabina Secures 1st Office Tenants at New Manhattan Skyscraper
The firms are expected to move in by the end of the year.
New York–based developer and commercial real estate investor Rabina has signed the first three office tenants—totaling almost 29,000 square feet—at its 1,002-foot-tall Class A tower at 520 Fifth Ave. in Manhattan.

The 88-story skyscraper reportedly will be the tallest mixed-use building on Fifth Avenue when it opens this fall.
The inaugural tenants are Ancient, a New York City-based private equity investment firm; JAB Holding Co., a global investment firm; and an unnamed New York City–based biotechnology hedge fund.
The tenants are expected to move in by the end of the year, once the building is complete, a Rabina spokesperson told Commercial Property Executive. He added that the building has about 200,000 rentable square feet of office space across 25 full floors.
