The objective of the DESIGN'IN project is to strengthen and stimulate the development of city centre shops through the integration of design, with a special focus on artisan designers and the cities of Mons, Tournai, Kortrijk and Lille Metropole. Indeed, in the face of competition from out-of-town shopping centres and changes in consumer habits, the aim, in a cross-border perspective, is to make inner-city shops more attractive, to offer them prospects for cross-border development and finally to attract more prospects. Three coordinated and complementary campaigns are being implemented to achieve these objectives. First, the “DESIGN'IN SHOPS” campaign aims to encourage traders to use the services of design professionals, who come to take stock of their shop in pairs, one from each side of the border, and make proposals for improvement. The shops are submitted to the vote of a new public in each city through a discovery tour. The second campaign concerns the provision of a temporary sales space for artisan-designers alternatively in the four project cities in order to test the market on the other side of the border. This space can be both a place of creation and/or manufacture and a place of sale. Finally, the third campaign aims to use design as a factor in the development and attractiveness of the territory. By launching calls for projects, the objective is to attract projects to enhance urban space through ephemeral or permanent developments via the principles of co-construction and design thinking... The aim is also to attract a new clientele from the other side of the territory.
