NEW YORK CITY-Office investment firm RDA Ventures is moving its corporate headquarters to 104 West 40^th St., GlobeSt.com has learned exclusively. The firm will take the entire 19^th floor in the 20-story, 210,000-square-foot building, owned by New York-based real estate private equity and asset management firm Savanna.

The deal continues a trend of strong leasing activity at the tower, which saw over 60,000 square feet of new office leases as of July 2011. Other new tenants here include TKP New York Inc., a Japan-based professional services firm who took a 10-year, 31,947-square-foot lease, and nonprofit organization Daytop Village Foundation who inked a 29,988-square-foot lease, filling the second, third and fourth floors, respectively. With RDA on board, the building’s total occupancy has now ticked up to 66,610 square feet.

Shep Wainwright, managing director of Savanna, says in a statement to GlobeSt.com that the firm is “thrilled” to welcome RDA to the tower and continue leasing success at the property. “The building’s prime Midtown location, premier office space, and exquisite lobby continue to drive steady demand,” he says.
