I forget what it's called, but something like "airplane view" architecture is also bad urban design. It's when centralized planners have lofty goals and design huge neighborhoods and plazas that look good from the air. There are towers, gigantic lawns, and a projection of power rather than chaos. There are various Latin American cities guilty of this. I'm struggling to recall the words and examples, so please help me out!
I believe we are talking about the exact same thing; “bird shit” is a play on words of “bird’s eye view”, meant to convey the planner’s/architect’s lack of thought or contempt of the actual people on the ground.
