There's one just a little far down the road here that we could have a look at and perhaps I could show you that.
You're listening to Crowd Science from the BBC World Service.
I'm Caroline Steele and I'm with one of our listeners, Siobhan.
She's introducing me to part of her London neighbourhood.
Yeah.
Okay.
So it's sort of.
It's brown.
It has very small windows, like very small windows.
All the windows sort of look like bathroom windows, I would say.
I mean, I think the style is brutalistic in its architecture.
It's got very monolithic sides, small windows, shadows, monotone colors, and has a sort of strange design through the middle.
We're stood in front of a building.
She often walks past.
It almost has the outline of a roof, but it's placed in the middle of the building.
It looks like someone's taken a brutalist building, flipped it on its head and then removed the windows.
