Cezanne St Honoré is a property complex dedicated to office use. It is located in the central business district in Paris. The renovation of common spaces, and particularly the basement, has been the occasion to create an area dedicated to conviviality, as well as an exceptional auditorium. Mirror-polished GHOST partition walls have been selected to equip this space. Equipped with monitored opacity panes, the appearance of the GHOST partition wall changes from full transparency to full opacity.
