This complex brings a certain monotony and repetition to the intersection, fronting on both Spruce Street and 38th Street. The 1974 book, Architecture in Philadelphia: A Guide, states “The two street fronts immediately bring to mind characteristics of Philadelphia row houses, many of which likewise had their ground floors devoted to shops.”
The complex was designed by Geddes, Brecher, Quails & Cunningham in 1969. The firm was based in Philadelphia and designed several local buildings. A bit more information on them can be found here. The complex also contains a performing arts complex on the east end.
