This home in Vincennes was renovated by Atelier Zundel Cristea. The primary goal was to conceive of a beautiful structure with quality spaces in which people feel good. So the designers made all the high-efficient elements are almost invisible, yet perceptible. The heating is geothermal, with the installation of a heat pump. Interior comfort is ensured by double airflow ventilation. On the roof there are solar panels as a means to produce clean, hot water. The interior décor is ultra-minimalist, with lots of white and light-colored wood in décor. The indoors is connected tight to the outdoors thanks to the glazed walls. This is what we call efficient and stylish!
