This project to restructure/extend a building originally constructed by our agency 10 years ago is a logical step in the (re)development of the Forum Seine ZAC (mixed development zone). Originally designed as a closed space within a heavily industrial area, we are now transforming the building by expanding it and opening it up to the city, installing a street running through the complex and retail units. The living facades feature inlaid greenhouse areas that give the building a sense of rhythm and play with levels.
