the architect, employed the grand scale and urban presence of pre-war federal architecture, but relied on "simplicity and architectural expression based on adaptation to functions". The building's H-plan was generally composed of an eight-floor rectangular block that intersected two perpendicular six-story wings on the east and west elevations. These secondary pavilions projected forty feet beyond the main building envelope to the north and south, and provided 20-foot setbacks at the sixth floor. A repetitive vertical fenestration pattern classically organized according to base, body, and attic, with recessed aluminum windows surmounted by Virginia serpentine spandrels, unified the main block with its flanking elements. Juxtaposition between the building's dark attenuated verticals with the light, planar mass of its limestone walls also alluded to the traditional colonnades seen in the Municipal Center buildings of Harris and Wyeth, Cret's Folger Shakespeare library of 1928-32 and even to Justement's own architecture of the 1920s and 30s. (Note that Justement used no pediments, entablatures, or porticoes, as seen in the Municipal Center, Judiciary Square and Federal Triangle Buildings.) These traditional references were further enhanced by the incised flute-like lines of the window returns, and the building's tripartite organization. The base (first floor) used floor-to-ceiling openings for both windows and doors. A projecting granite frame defined these voids and separated the lower portion from the piers above. The rigorous colonnade then marched across floors 2-4 on the side pavilions and floors 2-5 of the central block. Smaller square windows on the fifth floor of the side wings and the sixth floor of the central block defined the attic floor of the classically organized facade. Although the E. Barrett Prettyman Federal Courthouse exterior showed strong classical influences in its fundamental geometric articulation, its facades also reveal interest in the modern aesthetic. The facade composition relied on the juxtaposition of dark attenuated verticals with light, planar sheets of limestone. This architectural reliance on the subtle (light, shadow, and richness of material) indirectly responded to the increasing popularity of Modernism. One contemporary writer labeled the building "a rather conservative version of modern architecture. . . in order not the conflict with the traditional architecture of the other buildings on the Federal Triangle." Chief Justice Harold M. Stephens' comment recounted a fundamental element of modernism: "We wanted the building to be functional, not monumental." As a dual classical/modern expression, the building remains a period work, and evidences the federal government's search
