This is the largest privately owned building in Paris and was re-lit by Lighting Design International in 2004. The concept was to light the building in a dynamic way to draw attention to the size of the development.

Colour change is a major part of the scheme and the linear LED CLS system was used in the key feature atrium bridges above the reception area.Yellow, orange and red are used in the early evening, turn to blue and deep purple later at night.
