We are an international architecture office based in Paris. On the occasion of our retrospective at the Aedes Architecture Forum in Berlin and the publishing of an exhibition catalogue, we created this augmented reality app. Visitors (for the exhibition) and readers (for the catalogue) will be invited to download the J+M app and taught that it will swich directly to their camera and when they will be able to see one of our marker on their screen it will attach the corresponding 3D model of our buildings. Then they will be able to walk around it, even get inside.
