New York-based Ennead Architects has been selected to design the Peabody Essex Museum’s (PEM) $200 million 175,000-square-foot expansion. The expansion is expected to open in 2019.

The expansion project is part of the museum’s $650 million campaign. The expansion will add approximately 75,000 square feet of new galleries; public program and education spaces; a restaurant; and allow for improvements to the museum’s collection, conservation and exhibition processing areas.

Ennead was chosen following the completion of the first phase of the building project, executed by London-based Rick Mather Architects. This initial phase included master planning and the renovation of the Dodge wing, which will reopen in October with a new and expanded Art & Nature Center and other special exhibitions.

Ennead previously designed the expansion of the Yale University Art Gallery, as well as projects at the Brooklyn Museum, Natural History Museum of Utah, William J. Clinton Presidential Center and the Rose Center for Earth and Space at the American Museum of Natural History.
