The Cannon House Office Building is a six-story Beaux Arts structure constructed to provide office space for the U.S. House of Representatives. The building was originally constructed between 1904 and 1908, in 1913 the fifth floor was added. The trapezoidal building features a rotunda in the northwest corner, formal committee rooms, three underground tunnels, a marble façade on the street elevations with carved decorative features and a limestone façade on the courtyard elevations.
The program calls for a total interior and exterior building rehabilitation. As a consultant to Shalom Baranes Associates, JMA Preservation is responsible for the restoration (repair and cleaning) of historic materials including the marble, limestone, granite, ornamental plaster, tile, wood, decorative metal, and light fixtures. The work began with a program of requirements and has progressed through construction documents for five phases of work. We are currently performing construction administration for the second phase of work.
