About Postal Square

In 1990, Hines was hired by the United States Postal Service to renovate and restore its historic city post office in Washington, D.C. Later renamed Postal Square, the project includes 950,822 square feet of office space, 10,000 square feet of retail services, a 40,000-square-foot postal facility, a 75,000-square-foot National Postal Museum and parking for 420 cars. The historic renovation and completion of a new 300,000-square-foot structure addition to the inner courtyard was completed in June of 1992. The Postal Museum, which was designed by Florance Eichbaum Esocoff King, was completed in July of 1993. The Historic Lobby at Postal Square is available to corporations and non-profit organizations as a special occasion venue.
