De Ferla prestige presents the former workshop of Karl Lagerfeld. A place steeped in history and emotion, nestled in the heart of Paris's elegant 7th arrondissement, a stone's throw from the Quai Voltaire. Discreetly installed at the back of a courtyard, out of sight and out of mind, this confidential space is much more than an apartment: it's an artistic manifesto, a life's work, a fragment of the designer's universe. With 290 m2 of living space and 318.85 m2 of floor space spread over three levels, Karl Lagerfeld received his close friends and family, designed his collections and imagined tirelessly. The interior architecture, conceived by Lagerfeld himself, blends generous volumes, futuristic lines, sculptural railings and noble materials. Later taken over by an art and design enthusiast, the space was entirely reinterpreted by designer Pauline Leprince, who preserved the soul of the creator while infusing a contemporary, elegant touch. The result is spectacular: a suspended, almost unreal atmosphere, where every detail counts. Two bedrooms, including a master suite, an immense dining room, a professional kitchen, a bar, a wine cellar, a yoga room, a sauna, a hammam... All fully furnished and decorated with made-to-measure pieces, in a subtle balance between wood and steel, soft curves and assertive lines. This exceptional property, in perfect condition, offers rare potential: it has official authorization for hotel use, enabling seasonal rental, particularly for business events or prestigious stays. Potential rental income is estimated at 700,000 euros per year. A true showcase for collectors, investors or aesthetes, this unique apartment combines history, architecture, profitability and rarity. An iconic property in the heart of the Left Bank. This property has a dual use: offices and hotel accommodation, guaranteeing operational flexibility and lasting value.
