NEW YORK CITY-The 280,000-square-foot renewal and expansion oflaw firm Winston & Strawn at Tishman Speyer Properties’ 200Park Ave., and the consolidation of Natixis into 182,200 squarefeet at Mitsui Fudosan’s 1251 Ave. of the Americas, rank among thelargest office leases seen in Manhattan this year. Yet whilethey’re the biggest deals announced so far this month, GlobeSt.comhas already reported about 520,000 square feet of Manhattan officeleases since Dec. 1 that don’t include these two transactions.

And here’s nearly 160,000 square feet more announced on Mondayand Tuesday of this week: Regus for 26,112 square feet at 41Madison Ave.; Adspace Networks in a 10,835-square-foot headquartersdeal at 99 Park Ave.; the Richline Group for a 32,488-square-footrelocation from Mt. Vernon, NY to 1385 Broadway; RizzoliInternational Publications and M. Booth & Associates taking13,487 and 26,974 square feet, respectively, at 300 Park Ave.South; and a trio of deals at 499 Park Ave.: Woodbine CapitalAdvisors with 11,300 square feet, Halstead Property for 17,500square feet and a 20,000-square-foot expansion by CantorFitzgerald.

Add all of these up, and the total for the first half ofDecember would be nearly 1.1 million square feet, just in terms ofdeals large enough to be reported on GlobeSt.com. (The New YorkPost first reported in mid-November that a Natixis deal wasimminent.)
