The Ile-de-France region is home to more than 650 third places, with strong growth since 2015. This proliferation is a reflection of the entrepreneurial dynamics within the French territory and the development of teleworking. These are shared workspaces, often protean, creative, innovative, hybrid and multifunctional. They welcome more and more independents, favouring itinerant, remote and collaborative working. In order to illustrate the diversity and richness of these spaces, the Institut Paris Région (Paris Region Institute) travels the regions of Ile-de-France to meet them and give voice to the stakeholders, project leaders, managers, facilitators, users and communities that make up these places.
