the "KC architectural style" is just early 1970s brutalist (arrowhead, crown center, old KCI), which we are trying to replace with something else.
they could have gone Deco, to echo (lol) the P&L building, City Hall, Jackson County Courthouse, Municipal Auditorium, etc, but that would have just been pastiche and that is also not specific to KC.
the Shirtwaist home is the only architectural style that i know of that is truly unique to KC, and that is obviously n/a to an airport or any large commercial building
