Paris – Urban connections in Paris could be restored by an inhabited garden footbridge between the 12th and 13th arrondissements. The so-called Green Line across the Seine would host greenhouses, incubators and classrooms for new generations and evolving uses.

An inhabited garden footbridge prototype known as “The Green Line” is a proposed link between Bercy Village and the Messéna district in Paris. It would restore urban connections, promote social and cultural innovation, and generate a functional urban continuum between the 12th and 13th arrondissements.

With the use of flexible and mutable shared spaces, the creator Vincent Callebaut Architectures imagined a structure that “adapts to the needs of new generations and to new constantly evolving uses”, according to an article in ArchDaily. As well as rooftop and horticultural greenhouses to drive awareness of eco-gastronomy and alternative consumption, the proposal would contain classrooms, a research centre, co-working laboratories and incubators.

The Green Line would also meet new needs for flexibility and nomadism, and be an example of the sustainable management of air and water through its green spaces, themed gardens and phytoremediation lagoons.  

It was designed by Vincent Callebaut Architectures for the international competition Reinventing Cities – C40.
