SL Green's 100 Park Avenue was the first of Park Avenue's International Style high-rises. Located at the corner of East 40th Street, the modern glass and steel tower was completed in 1949 and replaced the Murray Hill Hotel, which dated from 1883 and whose residents put up a fierce battle against the new development. The building's current owner, SL Green, is wrapping up an 18-month, $72 million capital improvement program that includes a LEED for Existing Buildings ("LEED-EB") application aiming for a Silver rating from USGBC. The project includes upgraded building infrastructure, a new facade and windows, and a new lobby and elevators; BOMA named the tower its Best Renovated Building of the Year for 2007.
