Two out-of-town, Am Law 100 firms announced major Manhattan office relocations Thursday, with Akerman making room for a big expansion and Cozen O’Connor consolidating its New York operations in the World Trade Center.

Currently located at 666 5th Ave., Akerman said it signed a lease to relocate its 126 New York lawyers into the Mitsui Fudosan America building at 1251 Avenue of the Americas. The 100,000-square-foot office, which has space for 185 attorneys, will occupy the 37th and 38th floors, as well as part of the 35th floor. DLA Piper and Lowenstein Sandler also have offices in the building.
