This house, built like a cube, is airtight and perfectly insulated. Thanks to the warmth of the earth, its temperature is stable all year round. In the middle of winter, a pellet stove is enough! And in summer, the cool shade of the plants flowering on the pergola offers a beautiful softness. Outside the base are the greenhouse, the technical room and a garden shed. Built with as many ecological materials as possible, it is very bright and opens onto a terrace and a garden. Space is maximized by the absence of a corridor, the replacement of the living room with a TV corner and an office installed on the landing at the top of the stairs.
