Recognised as a UNESCO World Heritage Site, The Hôtel Solvay is widely acclaimed as the pinnacle of Victor Horta's architectural achievements. This groundbreaking architect challenged conventional architecture, addressing every issue through the lens of technological advancement—whether it be spatial design, materials, heating, ventilation, or lighting. From the floor plan to the selection of marble, from furniture to chandeliers and carpets, everything was meticulously designed by Horta. Françoise Aubry, a renowned Victor Horta specialist, narrates the story of this quintessential Art Nouveau masterpiece.
