Wasn't the vile practice of saving facades of historic structures originated in Philadelphia, Steve, the fountainhead of American preservation ever eager to get in bed with real estate vultures?
Philadelphia doesn't originate anything. It just reenacts things.
For example, when Mitchell/Giurgola Architects saved the Egyptian Revival (or should that be Egyptian Reenactment) facade at the new Penn Mutual Tower (1975), I saw this design solution as a reenactment of the James Stirling with Leon Krier Derby Civic Center competition design (1970) where the facade of an historic Assembly Hall at the site was reused as the facing of a band shelter.
I wonder if the reconstruction of Munich, Germany after the bombing of World War II can also be seen as "the vile practice of saving facades?"
Giurgola reenacts Stirling in at least two other designs: the Adult Learning Research Laboratory (1972) at the American College of Life Underwriters reenacts the Florey Building for Queen's College (1966-71), and the Mission Park Residential Houses (1972) at Williams College reenacts the Student Residences for St. Andrews University (1964-68).
Giurgola didn't know what to do, however, after Stirling saved a crumbling historic facade within the Museum for Nordrhein Westfalen (1975) competition design.
