Shopping K is a very minimalistic commercial center designed by the architect Robbrecht & Daem is lit with ovoid luminous objects, integrated in the ceiling of most floors and with monumental color changing donuts suspended from the roof of the atrium. More technical lighting is added in between the ribs of the roof and on the ceiling to provide the required illumination to the floor. Small light sources are also integrated into shopsigns to minimize its size and graze the rough structure of the stone pillars separating the shops.
