In Chambesy, on a 2,000 m² wooded plot with protected century-old trees, 3 contiguous luxury villas bring the concept of a “bridge villa” to life. The lines and areas have been carefully designed to free up as much living space as possible on the first floor, while the ground floor is hollowed out to create a “suspension bridge” effect. Clear views and transparency provide continuity between the 2 parts of the garden, while maintaining appropriate distances for privacy. Nature takes pride of place; prominently displayed on the roof and on the planted facades. The large picture windows and skylights in the ceiling above the interior patios keep these villas bathed in natural light. The overall floorspace of each villa is 180 m², with 7 rooms spread over 3 levels. The first floor consists of 3 suites with dressing rooms and en-suite bathrooms, as well as large south-west facing terraces. On the ground floor, the living areas are spacious and west-facing. The basement is fully excavated and includes a games room, a wellness area, and a wine cellar. To save space, the parking structure shared by the 3 villas takes the form of a 2 level car lift. The villas are energy self-sufficient and equipped with smart home automated systems. Thermal and photovoltaic panels on the roof and individual heat pumps connected to geothermal probes have earned these villas the very high energy efficiency certification; each villa is also equipped with an Oblo barometer offering outstanding accuracy. The triple glazing and construction materials consisting of reinforced concrete slabs, a roof slab, and wooden walls all combine to provide optimal insulation. Because of their location near the Geneva airport, these villas have been designed to minimise the noise disturbance for those inside. They each have a planted and sound-absorbing blind facade that provides excellent acoustic protection, in addition to the strategic orientation of the glazed walls away from the airport.
