GPT describes it best (in a rare stroke of luck) here:
This kind of space isn’t trying to be liminal in a way that stands out (like an empty mall corridor at night). It’s the kind of liminality that people don’t consciously register because it’s been polished just enough. It has scale but not weight, presence but no pull.
it’s a space that isn’t hostile to lingering, but it passively discourages it. It’s not forbidding, but it’s subtly structured to make solo presence feel unjustified. You need a clear reason to be there, whether it’s a lecture, a meeting, or a class, and once that reason is gone, the space nudges you to move along.
How I described it:
In a way, it's a genuine liminal space, and designed to be, but also designed to be just enough that most don't register it as such. It's not openly hostile or unsettling. It's meant to be looked past but when people do look closely enough, it's impressive but not striking, enough to get people to move along.
