“The Unexpected” at the gates of the Vexin: A spectacular house and its indoor swimming pool.

Just an hour from the hustle and bustle of Paris, on the border of the Val-d’Oise and Oise departments, stands a residence that defies convention. “L’Inattendue” (The Unexpected) is more than just a house; it’s an immersive experience, an organic haven nestled in the heart of a bucolic village, where architectural audacity meets the serenity of the Vexin region.

Located near Marines, this house, with its unusual and surprising appearance and dimensions, was conceived around a lifestyle far removed from our standards and redefines the codes of exceptional living. Whether an atypical second home or a lifelong retreat, it’s the ideal haven for timeless weekends or for a transformed everyday life.

An architecture of light and glass.
The tone is set on the ground floor. At the heart of this extraordinary architectural creation, the living space stands as a veritable glass cathedral, where the boundaries between indoors and outdoors naturally dissolve. More than just a reception room, this light-filled volume is the beating heart of the house. At its center, plants, wood, and stone blend harmoniously, constantly reminding us of the enduring connection with nature. Daily life revolves around this tranquil strength, its rhythm dictated by the changing seasons that filter through the immense glass walls.

The ambiance is both majestic and intimate. The open fireplace, the focal point of the living room, invites contemplation and promises cozy evenings by the crackling flames. A perfectly integrated, modern kitchen combines functionality with minimalist aesthetics, offering an ideal canvas for culinary enthusiasts.

The basement sanctuary: A sensory journey.

The experience becomes truly exceptional when you descend a level. Far from the classic image of a traditional basement, this space has been sculpted to inspire wonder and designed as a unique and dreamlike extension of the house.
From the living room, your gaze is irresistibly drawn downwards. A visual perspective reveals a mineral realm, accessible via an organic staircase connecting the world of light to that of the imagination.
Once downstairs, the magic takes hold. The rock walls, crafted by artisans of illusion, shelter a grotto dedicated to leisure, a place for those who collect emotions. A heated swimming pool and its lounge area invite total disconnection and absolute relaxation far from the hustle and bustle of everyday life.
Continuing from this level, a spacious and generous volume completes the space, ready to host billiards nights, movie nights, and other festive occasions.
The audacity reaches its peak with the master suite. Hidden behind a glass block wall, this bedroom is an intimate retreat offering a unique nighttime experience.

A property that plays on duality.

While the house surprises with its originality, it is also perfectly designed for everyday living. Every space is optimized, every flow is seamless, making this a living space that is as practical as it is spectacular.
Rarely has a property so aptly deserved the adjective “unique.” This house in Chavençon is the perfect balance between the comfort of a functional home and the allure of bold architecture.

The exterior: a blend of openness and discretion.
The exterior of this property doesn’t just surround the house; it extends it. The garden, with its decidedly bucolic feel, is arranged around the house and its two terraces. A first room, dedicated to the three ground-floor bedrooms, offers an unobstructed view of the surrounding nature, while a second room, directly connected to the kitchen, serves as the central gathering place for shared moments.

The atmosphere of the property makes it a haven of conviviality, offering complete privacy and an immediate escape.

The location of this charming village embodies the art of country living without sacrificing the vibrancy of city life. Ideally situated on the edge of the Val-d’Oise department, this property offers excellent accessibility. The Cergy-Pontoise RER A station and secondary schools are 25 minutes away. Access to Saint-Lazare station (line J) and La Défense (RER A) is within an hour. Grocery stores, markets, amenities, and schools are all less than 10 minutes away by car.
