In the east of Paris Atelier du Pont has built an unconventional office building for the housing association RATP Habitat. Located in a courtyard, the building opens primarily upwards – with lig htwells and planted roof terraces. Not only are these terraces us ed during breaks by the roughly 80 staff members, a “green team” made up of employees also grows vegetables on them. Support with this work is offered by V eni Verdi, an organisation that encourages urban farming in Paris. The client for the new building is a daughter company of the state-owned RATP Group, which operates local transport around Paris.
