Ideally located in the highly sought-after Golden Triangle of Garches, this stunning Napoléon III-style residence has been fully renovated to combine historical charm with contemporary refinement. Set within a beautifully landscaped and gated park, the property offers nearly 600 sqm of living space just minutes from the town center, train station, and prestigious international schools. On the ground floor, generous volumes and flowing layout define the living areas: an elegant entrance hall with original tiled flooring, a luminous living room with fireplace, a cozy lounge, guest restroom, and a bespoke kitchen open to a dining and living area. At the heart of the home, a striking metal-framed glass extension floods the interior with natural light and creates a seamless transition to the outdoors. This contemporary feature enhances the sense of space and provides open views of the landscaped garden. Upstairs, the sleeping quarters are divided into distinct zones: two children's bedrooms with integrated storage, a bathroom, and a balcony on one side, and three additional bedrooms each with private shower rooms. The top floor hosts a stunning master suite with views over Paris, including a bedroom, two dressing rooms, a bathroom, and a separate shower room. The fully finished basement includes a professional-grade home cinema, an independent family room, a temperature-controlled wine cellar, and technical utility spaces. A separate 50 sqm guest or staff house at the entrance offers multiple possibilities (live-in staff, guests, or home office). Multiple parking spaces complete this exceptional property.
