Holland & Knight’s New York office will relocate uptown to slimmed-down quarters at 31 W. 52nd St. The 82,551-square-foot 15-year sublease, set to begin in January 2010, is for more than three floors directly leased by Clifford Chance.

Holland & Knight now occupies 105,000 square feet at 195 Broadway, where it has been located for 22 years. William J. Honan, an executive partner who practices in the litigation section and heads the firm’s maritime practice group, said that the sublease at West 52nd Street will be for floors 11 through 13 and part of the second floor.
