The C&A building in Eindhoven will be modernised and therefore UNStudio designed several glass structures for the building. One of these glass structures are four glass boxes of 5,5 meters wide and 7 meters high, which are floating in front of the existing façade. In addition, each glass box contains a work of light art designed by Arnout Meijer. LED strips illuminate the box from the inside, while the reflective film on the glass creates an unusual and striking effect. To optimize this effect no metal connections were allowed in the design. The size of 5,5 by 7 meters was exceeding every international standard format in the glass industry.
