‘MixCité’ unites the Pershing and Ternes areas though combined urban conception and programming. The project is centred around two new axes: one pedestrian walkway which runs diagonally along Rue Sablonville to Porte des Ternes, and a huge gallery linking Porte Maillot with Boulevard d’Aurelle-de-Paladins. This gallery offers numerous possibilities with its multifunctional spaces: shared accommodation, offices, restaurants, recreational areas, teaching spaces, and so on. Each section is modular and quickly demountable. Prefabrication in wood and concrete reduces construction time and worksite issues, and a range of environmental features are incorporated: a high performance thermal envelope, grey water heat recovery, reduction of atmospheric pollution using roof-level biofilters, regulation of energy consumption and over 3,000m² of shared garden space to encourage biodiversity. On the Ternes-Villiers side, the project will develop mixed programming covering 24,650m² of predominantly service sector industries, of which 19,700m² will be taken up by offices and the existing international bilingual school (EAB).
