Set on a plot of over 3'000 m², this impressive property benefits from a privileged location in a calm, secure, and preserved residential environment, offering a pleasant view of the lake.
Built in 1984, the house currently consists of two independent dwellings, arranged in a mirror-like fashion, which can easily be reunited to create an exceptional family residence. It develops approximately 960 m² of living space and a total useful area of around 1'440 m², spread over three levels.
The two parts combine to offer a total of 9 bedrooms and 9 bathrooms, as well as vast reception and living areas.
The property also features staff accommodation, including a kitchenette and independent access, as well as a particularly comprehensive wellness area with a gym, sauna, steam room, and jacuzzi.
Outside, the fully enclosed garden guarantees intimacy and tranquility. The amenities include a heated swimming pool, two beautiful terraces, a barbecue area, and an electric gate. A large, heated asphalt courtyard also allows for easy parking throughout the year.
Three external garages and several parking spaces complete the amenities of this property.
The original finishes testify to a choice of quality materials, such as marble, stone, and woodwork. However, significant renovation work is to be expected, offering the opportunity to rethink the spaces and reveal the full potential of this exceptional property.
