Galleria Hall is a Department Store in Seoul which in September 2004 had a façade-lift done by Dutch architects UN-Studio.
4330 glass disks were applied on the metal substructure of the existing façade. The discs were treated with a special iridescent foil, which causes constant changes in the perception of the façade.
At night, a special lighting scheme, designed cooperatively by UN Studio and ArupLighting, illuminates the discs by reflecting the dynamics of the weather conditions that happened during the day.
UN-Studio also renovated the interior of the building, using bright light-colored walkways to improve orientation as well as to give the store a totally new and fresh makeover.
