Located in a sought-after area known for its proximity to Saint-Germain-en-Laye, on the hills above Le Pecq, this elegant nineteen thirties home—spanning approximately three hundred fifty square meters (four hundred ninety square meters in total)—sits on a one thousand seven hundred square meter lot and captivates with its well-preserved Art Deco architecture and views of the Seine Valley. The charm of the old blends perfectly with a high-quality contemporary interior, creating a harmonious and unique atmosphere, enhanced by an exceptional view. Spanning several levels, the house makes an immediate impression upon entry with its spaciousness, characteristic of the fine residences of that era. On the ground floor, a spacious double reception area with a fireplace and a generously sized, light-filled dining room opens onto a long terrace with commanding views of the valley. The kitchen, completely redesigned in a resolutely modern style, centers around a state-of-the-art glass roof that floods the space with natural light, featuring an island and a dining area—accessible directly from the tree-lined terrace. An office, a home theater, and a guest restroom complete this level. The original staircase leads to the spacious landing on the upper floor, which serves five bedrooms (seven bedrooms are possible), including a full master suite—with a shower room, large walk-in closet, and additional room—as well as a perfectly preserved bathroom featuring blue and gold mosaics and a laundry room. On the lower level, the arched garden-level floor opens directly onto the garden and its pond, which has been preserved in its original state and offers great potential for renovation. It is complemented by several utility rooms—a boiler room, a cellar, and a pantry. The grounds are organized into landscaped sections—a lawn with a pond, a gently sloping garden, and stone staircases—within a peaceful and well-structured setting. Quick access to the Réseau Express Régional A line at Saint-Germain-en-Laye; local schools (Saint-Erembert, Saint Dominique, Général Leclerc etc.), and the Nationale 13 highway toward Paris and the West.
