[Buddha-l] Korean monastic architecture

[Alex Wilding]

My daughter asked me if I could find out whether what I describe is a real
feature of the architecture one might find in a Korean monastery or temple,
or whether it was just a cinematic metaphor.
She told me of a film (moderately well known, I believe) set in a Korean
temple (on some kind of island in a lake - sounds like something off a
chinoiserie plate!). In the temple is a central area with a Buddha statue,
and there are a couple of rooms off. The curious feature is that although
there are doors to the rooms, there are no walls. The protagonists go from
room to room through the doors, but at a later stage go straight through the
(non-existent) walls.
It is easy to understand this simply as a metaphor, but she wonders whether
perhaps it is based on a real architectural style used in Korean monasteries
and/or temples. Can anyone tell me?
Thanks in advance
