Andorra, Philadelphia
Andorra was established and developed in 1950 and therefore has stereotypically suburban characteristics, such as a strip mall, many single or double-family dwellings set back from the street, and apartment buildings on large lots with ample off-street parking.[2] Houston worked with the Roxborough government to create an east–west roadway and two bridges designed by Paul Philippe Cret that would have crossed both the Schuylkill River and Wissahickon Creek; the plan was approved in 1927 but was never built.[3][2] In the 1940s, Houston unsuccessfully attempted to sell additional estate land to both the Veterans Administration, Temple University, and a proposed site for the Headquarters of the United Nations.The development included plans for over 5,000 single-family homes, duplexes, and apartments designed by Robert Rodes McGoodwin, although only 400 were ever built.Houston created an "Indenture of Covenants" for Andorra homeowners, which included stipulations such as no signs larger than one square foot, no “noxious, dangerous, or offensive behavior”, and a ban on raising livestock.
