I know the LAX “Theme Building” by William Pereira and Charles Luckman is the poster child for Googie Style, but I still don’t like that designation. After doing a Google image search I see eye catching work by Oscar Niemeyer and Eero Saarinen and even Frank Lloyd Wright. (I don’t see Le Corbusier, but can think of his projects that could easily be added.)
I thought “vernacular” was the term for design like the original Googie’s and similar ’50s and ’60s street architecture, but apparently that isn’t right either. I would actually prefer the tern “Street” architecture myself (no one cares).
With this broad definition of “Googie” anything by Bruce Goff would fall into this style and all the post-modernists, unless you add a restriction based on date.
I think Street or Googie style has to include neon or wild color and can include features like massive donuts and whimsical shapes like windmills and tepees. But should not include structures that were instances of mid-century architects exploring what they could now do with concrete and steel.
