JCDecaux is a global leader in urban advertising and street furniture. The company is present all over the world. The « Mairie mobile » concept was based on the idea to develop mobile information points. Going, being where the public is, where an event is taking place. For a city, an institution, an organisation, a festival, a bank, a brand, it gives more visibility, proximity and enables people to obtain information directly. We have developed this concept with two important points in mind: the vehicle’s impact when moving and when stationary. The deployment of the mobile arch gives the feeling of a small architecture, underlying the welcome inside it. The arch awakens a curiosity and gives a very special character to the parked vehicle. We managed this product directly with Mr Jean Claude Decaux and the coachbuilder from the concept to the production of the first "Mairie Mobile".
