That’s an interesting point. What college was that?
There is indeed brick brutalism that looks like this, but I wouldn’t label this building as such. Still, it can be a thin line between brutalism and postmodernism.
Either way, the way I use the postmodernism tag is, admittedly, very unscientific (it doesn’t help that I hate pomo). Anyting from late-modern until recent, where the architect gets too creative with all kinds of influences easily gets the postmondernism tag in my world.
