The brick colonial homes of Caster gardens were considered more prestibuous then the row homes located south of Magee Avenue which were part of the neighbrohood known as Oxford Circle (getting its name from the traffic circle located at the juncture of Oxford Avenue, Castor Avenue, and the Roosevelt Blvd, foremrly known as Hunter's Circle).
As the neighborhood developed, the area between Magee and Cottman Avenue, Whitake Avenue and Castor Avenue was mostly semi-detached and detahced homes. To differentiate this area from the row homes south of Magee and East of Castor Avenue, the use of the name Castor Gardens begain in the late 1960s and early 1970s.
As people began to indicate a preference for Castor Gardens as opposed to Oxford Circle, the names was applied to a larger and larger area, first encompassing the newest row homes in the area (North of Tyson Ave) and eventually encompassing the entire area foremerly known as Oxford Circle, while that name was relegated to the homes located south of Oxford Avenue which were older and smaller homes mostly built in the 1920s and 1930s. The housing stock in Castor Gardens were built as early as the 1930s, with construction halted during the years of World War II. The housing boom after World War II fueled additional construction, with the last homers being built on streets located along Cottman Avenue in 1956. Some spot building (building completed on a lot by lot basis) continued to the present day
