Why are we obsessed with liminal space?

This week, we discuss a new architecture-themed horror film, some concerning news about green walls and a new architectural term that one of our hosts has audaciously coined.   In this episode, Dezeen features editor Nat Barker and design editor Jennifer Hahn consider Backrooms – a surprise-hit horror movie from a 20-year-old director – and its origins in the internet's fascination with "liminal space".   Then, they talk through new research indicating that plastic-potted green wall systems could make fire spread up building facades faster than the cladding used on Grenfell Tower.   Finally, they discuss Nat's claim that a new architectural style has emerged in the UK and beyond.   This episode was recorded and edited by Miguel Santa Clara.
