 The post office was built in 1940 to a design by Leon Pernice, an architect based in West Springfield.It was built at a time when the federal government was emphasizing simplified styles whose designs could be approved and executed rapidly, providing jobs to the community.The building underwent a substantial remodelling and enlargement in 1968, when a large ell was added to its rear, and glass-and-aluminum partitions and fluorescent lighting were added to its lobby area.
