Moynihan left public service (temporarily) in 1965, and Harry McPherson, counsel to President Johnson, kept the Pennsylvania Avenue redevelopment plan alive and shepherded it through additional revisions. Nonetheless, rejuvenation of Pennsylvania Avenue and the area north of the street began occurring as early as 1965, even though no permanent redevelopment authority had yet been established. The first building to be developed under the 1964 master plan was 451 12th Street NW (at the site of the old Raleigh Hotel). The Brutalist style structure was designed by Edmund W. Dreyfuss & Associates, which worked closely with John Woodbridge (a staff architect for the President's Council on Pennsylvania Avenue and a member of the firm Skidmore, Owings and Merrill).
