Illhaeusern, Alsace. Just 600 inhabitants. A small village on the banks of a gently flowing river, a bucolic picture postcard from eastern France. In 2016, Danielle and Marco Baumann decided to extend their hotel’s capacity and to equip the Hôtel des Berges with a new annexe, the Spa des Saules. Architecture and interior design were entrusted to Jouin Manku, in collaboration with Silvio Rauseo. By way of a brief, the two designers were given carte blanche to design a place for rest and relaxation, a complete break, where time is suspended.
