Rejecting orthodoxy and grand narratives, postmodernism took shape in architecture, art and philosophy alike. While it’s philosophy, in my opinion, is nihilistic, narcissistic and ultimately despicable, postmodern architecture’s creativity and freedom from convention did produce some fascinating buildings.
Beginning in the 1960s, postmodernism hodgepodged (often disdainfully) multiple styles such as classical, modern, arts-and-crafts, giving rise to truly unique buildings. Defying are norms, boasting asymmetry, confusing themes, and taking pride in not fitting in with its surroundings, it is impossible to miss a postmodern office or home.
The house from Beetlejuice is an example of heavily re-fitted postmodern design. You don’t see a ton of postmodern architecture, but once you do you’ll never forget it. For better or worse.
