Mount Sinai Takes 26K SF on West 57th Street for Corporate Executive Offices



Mount Sinai Health System has taken 26,100 square feet at Empire State Realty Trust’s 250 West 57th Street for its corporate executive offices, Commercial Observer has learned.

The space spans the entire 15th floor of the 26-story building between Broadway and Eighth Avenue. Mount Sinai signed an 11-year lease, according to ESRT, with an asking rent of $67 per square foot.

“Mount Sinai is our third full-floor transaction since announcing redevelopment plans,” Thomas Durels, the director of leasing and operations for ESRT, said in prepared remarks. “They join a quality tenant roster, including COOKFOX Architects and GuildNet.”

As CO reported in March 2016, GuildNet, the insurance affiliate of Lighthouse Guild, took 37,680 square feet on the 530,716-square-foot building’s entire 10th floor and part of the ninth floor. COOKFOX Architects took 20,000 square feet on the 17th floor.

Chris Mongeluzo of Newmark Grubb Knight Frank represented Mount Sinai in lease negotiations. Keith Cody of ESRT represented the landlord along with Harry Blair and Sean Kearns of Cushman & Wakefield. Mongeluzo didn’t immediately respond to a request for comment via a spokeswoman and nor did a spokesman for C&W.
