In the center of Lugano the boutique Cartier was renovated on the basis of Architect Elia Valeggia’s project. The point of sale is located on the ground floor of a historic building and its restoration included an important change in the arrangement of the shop windows. Therefore, Diego Varan Render was charged with modelling the new outside and with realizing a photo-mock-up of the new project by adding it to the existing context. In this way, it was possible to simulate the change and to appreciate its artistic impact.
