Renovation of The Addison Gallery, constructed in 1931, a significant work of Charles Platt and one of the ensemble of Platt buildings which enclose the Great Lawn, the principal central campus space at Phillips Academy in Andover. The renovation provided climate control systems, daylight control systems, security systems, storage facilities, new basement gallery spaces, and landscape improvements including a new Sculpture Court to link the Gallery to its companion Arts Building, coupled with a new accessible entrance.
