Nancy, in north-eastern Lorraine, was France’s Art Nouveau hothouse, Emile Gallé’s École de Nancy an unlikely coming together of the region’s booming steel and glass industries and the sensuous, so-hot-right-then whiplash curves of the natural world. Visionary metal-worker turned Modernist architect and designer Jean Prouvé was also born into this milieu. This spendid mansion house, a particularly beautiful example of the signature local style and former family home, is an apt choice for design pilgrims to take in the city’s rich architectural heritage and museum collections. Owner Isabelle Jung-Hutin’s way with colour and mad, enchanting detail is moody and seductive; each room has a distinct look and design references. lavilla1901.fr
