Transa Basel SBB – where retail meets adventure. On 2,300 sqm inside Basel's main train station, Aroma designed a retail experience that brings the outdoors indoors. The centrepiece: the Transa Trail – Switzerland's first indoor treetop walkway. Spanning four floors, this multi-level timber structure connects levels through platforms, suspension bridges, and test stations for gear. Rather than conventional retail design, the space invites visitors to explore, test, and linger – transforming a transit hub into an outdoor destination.
