The Addison’s Expansion and Renovation

In the summer of 2008 the Addison embarked on a two-year renovation and expansion project, which has restored the museum’s 1931 Charles Platt building and created a 13,770 square-foot addition.

The new Sidney R. Knafel Wing, designed by Centerbrook Architects, provides a flexible, dynamic center for the Addison’s education programs, enables the museum to store its entire collection on site, offers generous new art handling spaces, and consolidates staff offices. All gallery spaces in the original building have been restored, including the Addison's signature rotunda with its celebrated Paul Manship fountain. State-of-the-art climate control, lighting, and security systems have been installed throughout the building, ensuring the Addison's ability to provide optimal care for its renowned collection.

At the heart of the Addison’s Sidney R. Knafel Wing is the new Museum Learning Center, a multi-purpose space designed to foster learning by engaging with works of art from the museum’s collection of nearly 17,000 objects. Featuring display areas for works in all media, digital projectors, flexible table and chair arrangements, and spectacular views of the Addison’s green roof and the Phillips Academy Great Lawn and Chapel, the MLC is well suited to the Addison’s broad audience base, which includes students from Pre-Kindergarten through high school, as well as adults.

The MLC is open to the public for research, reading, and relaxation. Whether visitors choose to explore the collections in person, online, through books, individually, with a group, or through a class, the MLC offers myriad opportunities to understand American art and connect it to broader historical and cultural themes.
