UNstudio have designed galleria cheonan building in korea.

the galleria cheonan building organisation employs a propeller principle. four stacked
programme zones, each thematically combining three storeys and containing public
plateaus, are linked to the central void. the concept of the propeller is a fluent upstream
flow of people through the building, whilst the propeller wings simultaneously stream
visitors outwards to the plateaus on the various levels. on the facades a gradual transition
from exterior surface to the interior plateaus accentuates the internal organisation.
the facade is double layered. both the outer glass shell and the inner skin comprise of
a linear pattern created by the vertical mullions. during the day the building has
a monochrome reflective appearance, whilst at night, soft colours are used to generate
waves of coloured light across the facade.
