The Administration Building on Treasure Island, San Francisco, is a Moderne-style structure designed by architects William Peyton Day and George William Kelham, completed in 1938. Originally constructed as a terminal for Pan American Airways' China Clipper transpacific flying boat service during the Golden Gate International Exposition, the building transitioned to administrative use when the U.S. Navy assumed control of the island following the exposition's conclusion. The structure, which blends Art Deco and Streamline Moderne aesthetics, later housed a museum until 1997. Listed on the National Register of Historic Places in 2008, the building remains part of Treasure Island's redevelopment following San Francisco's 2011 acquisition of the site from the Navy, with plans to restore its museum function.
