Once a year in Le Mans (Fran­ce), 50 cars dri­ve around a cir­cuit for 24 hours. For several con­se­cu­ti­ve years, we were asked to design a pop-up restau­rant right next to the track for enter­tain­ment – and of cour­se dining – pur­po­ses. Our Audi Racing Gar­den pro­vi­ded a cool cur­ve to off­set the hot tar. In kee­ping with the sus­taina­bi­li­ty award, which para­do­xi­cal­ly also exists for this race, the mate­ri­als and recy­c­la­bi­li­ty of the restau­rant con­cept ent­i­ced visi­tors from the out­set – after having expe­ri­men­ted with its basic struc­tu­ral appearan­ce as an ener­gy curve.
