History and Architectural Features

Designed by Alfred B. Mullett, best known for designing the San Francisco Mint, this 44,400-square-foot facility was constructed at an original cost of $200,000 to house the U.S. Post Office, Customs and Courts. Its unique features include an octagonal cupola and simplified Corinthian capitals characteristic of the Renaissance and Greek Revival styles. It originally featured gas chandeliers and 17 Vermont red-marble fireplaces.

The renovation included uncovering the 17-foot ornamental plaster ceiling, recreating the mahogany postal wall, installing historically accurate doors and pendant light fixtures, and restoring wood window frames.

Other recent improvements include upgrading the heating and ventilation system, replacing the boiler system, installing energy management controls and a new fire alarm system, restoring the third floor public corridor and the exterior masonry to its original sandstone facade, and construction of additional U.S. District Court jury rooms and assembly space.
