This building was built as the new headquarters of the telecommunications company. The idea was a decorative open light ceiling easy to demount with the plenum full of installations in black. Only the lighting system is integrated in the ceiling.
The working areas are 30B in white and the corridors 30B in black. There are several meeting rooms with 30BD to give this areas a different character from the open working spaces.
