Gosin, Waterman and Canete of Newmark Knight Frank and Larkin and McCuaig of Brookfield Office Properties arrange 1.2 million s/f lease

Brookfield Office Properties Inc. has executed one of the largest single-asset office leases in the city since 2008: Morgan Stanley signed a lease for 1.2 million s/f at One New York Plaza. "Re-letting this large block of space at One New York Plaza was a major strategic priority for Brookfield and we are thrilled that Morgan Stanley will remain in the building and be taking additional space," said Jerry Larkin, senior VP and director of Leasing of U.S. Commercial Operations at Brookfield. "This lease commitment is another example of the appeal and long-term viability of Lower Manhattan as a coveted market in which to do business." Under an existing sublease with Wells Fargo for 782,000 s/f and a direct lease with Brookfield for 34,000 s/f, Morgan Stanley currently occupies 816,000 s/f at One New York Plaza. Under the terms of the new direct lease with Brookfield, Morgan Stanley will expand its premises in the building by 337,000 s/f for a total of 1.153 million s/f, expiring in 2029. Morgan Stanley was represented in lease negotiations by Barry Gosin, Brian Waterman and Romel Canete from Newmark Knight Frank. Jerry Larkin and Duncan McCuaig represented Brookfield in-house. One New York Plaza is a 2.6 million s/f class A office tower located on the southern tip of Manhattan, adjacent to Battery Park. The building offers stunning 360-degree views of New York Harbor and the Manhattan skyline.
