Hidden from view and just moments from the Luxembourg Gardens, this extraordinary residence unfolds within a Directoire-era private mansion, once home to Madame de Chateaubriand. A discreet address where history whispers and timeless Paris reveals itself. Reimagined in its entirety with uncompromising attention to detail, this house-like duplex spans approximately 371 square meters (including 364 square meters under the Carrez law), offering a refined dialogue between classical elegance and contemporary comfort. At its heart lies a 225-square-meter private garden — a rare and precious oasis in the center of Paris — complemented by two gracious terraces, ideal for quiet mornings, elegant entertaining, and long summer evenings beneath the Parisian sky. The main level is devoted to living and entertaining, featuring a double reception, a private study opening onto its own terrace, a media room, and a generous eat-in kitchen, conceived as a warm and welcoming gathering place with direct access to a second landscaped terrace. On the garden level, serenity prevails. A luxurious primary suite with dual bathrooms and walk-in wardrobes offers privacy and comfort, while five west-facing bedrooms, bathed in golden afternoon light, open gracefully onto the garden. An independent studio, laundry room, cellar, and two private parking spaces within the courtyard complete this rare offering — a singular opportunity to own a residence where heritage, beauty, and the Parisian art of living converge.
