Céline Flagship Store Cheongdam is an alteration project with a unique façade design added to the existing building. The existing hipped roof is replaced with a flat roof to emulate a modern look of the surrounding modern buildings. The porous facade is composed with a various length of clay bricks and the lightings in the cavity wall illuminates an ambient nighttime. The combination of the natural lighting through the porous brick facade and the Barrisol lighting from the ceiling in inside offers a memorable experience to the visitors.
