Smithsonian Institution
National Postal Museum
The William H. Gross Stamp Gallery at the National Postal Museum is set in Washington, D.C.’s historic Postal Square building. The renovation and interior fit-out of the circa-1914 space created a 14,000 SF exhibition area that chronicles the first 100 years of U.S. postage stamp history.
Mueller’s services included the replacement and reconfiguration of the entire electrical distribution system for the gallery, which accommodates the most extensive philatelic gallery in the world.
The space includes public exhibit space, traveling exhibit space, and classroom educational space. The expansion also allows direct access to the museum from Massachusetts Avenue, featuring a Welcome Center for the entire museum in the historic lobby, dating to 1914, of the Postal Square Building.
The design balances the requirements of a “black box” for exhibits—to control light, temperature, humidity, and security to protect the artifacts—and the desire to reveal the historic architecture and the original oversized windows. Meticulous planning and coordination of all new MEP and other engineering systems spotlight architectural details and enhance the exhibit space. The remaining original historic features were restored, such as the chestnut paneled Postmaster’s Suite.
