The house of Technopole is an original hybridisation of programs which seeks to create an animated meeting place for events and office functions in the heart of a new district of activities dedicated to industry and new technologies. The shape of the building arises from the interweaving of these diverse activities. Offices and meeting rooms are gathered at the entrance of the site in a large glazed square which is conceived as a mediatic scaffolding offering open views on each floor. The ground floor accommodates temporary activities, in connection with public areas, while at its centre the auditorium takes on the role of a public square surrounded by an expansive gallery housing entries, expositions and temporary offices. In this manner, the building responds to the challenge of creating a visible and identifiable landmark at the scale of the urban agglomeration. The regular grid of each wing opens onto the landscape of the Technopole and simultaneously defines both the functional and symbolic origin of the district. The architecture reinterprets the vocabulary of production infrastructure as an expression of a third industrial revolution, a transition towards a sustainable economy as a result of the simultaneous development of environmental and information technologies.
