In January 1963, GSA estimated that construction on the building would begin in 1964, and be complete in 1967. In June 1963, GSA hired the firm of Charles F. Murphy and Associates to assist with the design. Stanislaw Z. Gladych was the chief architect, and Carter H. Manny, Jr. was the partner in charge. Murphy and Associates struggled to meld competing views of what the building should be. The President's Council on Pennsylvania Avenue wanted a building with a pedestrian arcade on Pennsylvania Avenue side, and retail shops on the ground level on the other three sides. But the FBI rejected this view, instead advocating a structure which was bomb-proof on the first few stories and which had but a few, tightly secured access points elsewhere. Murphy and Associates initially designed a monumental building. This approach was rejected by GSA for wasting space and because it would draw criticism for its apparent misuse of taxpayer dollars on lavishness. Murphy and Associates next designed a "Chicago school" structure. This was a rectangular building whose front was aligned along an east–west axis rather than Pennsylvania Avenue. This created a strong setback on Pennsylvania Avenue, which the architects turned into a pedestrian plaza. Although this design was largely accepted, the setback was not and the building's south side was again aligned with the avenue. Although the FBI was not extensively interested in the building's architectural design, mid- and low-level managers meddled extensively in the building's details (even while working drawings were being completed).
