The Second Empire-style building soon proved to be too small for the city's needs, an issue compounded by the establishment of the Middle District Federal Court.
In 1929, chief of architectural design Louis A. Simon at the Office of the Supervising Architect under James A. Wetmore, completed plans for a new building on the site.
In 1985, GSA began a $4.3 million rehabilitation of damaged historic materials such as doors, light fixtures, and interior finishes.
Art Deco influences are apparent in polychrome (multicolored) ornamental details, low-relief geometrical designs, and decorative forms based on nature.
Most of the Washington Avenue facade is recessed at the third and fourth floors with engaged green serpentine columns highlighted by terracotta Corinthian capitals.
Historic materials include marble, bronze, clay tile, simulated stone, cast iron, oak detailing, and decorative stencils.
Each has oak-paneled wainscoting capped by a carved frieze at door height, interrupted by windows and the wall behind the judge's bench.
1, behind the judge's bench is a curtained area with oak columns and an entablature with a mural, titled Justice with Peace and Prosperity (artist unknown), installed soon after the building was completed.
Designed by the architecture and planning firm, Bohlin Cywinski Jackson in conjunction with hemmler + camayd architects, the annex fronts on Washington Avenue.
The artist worked with GSA staff, project architects, and the community to create artwork integrated into the building's design.
