That’s the description of the projet, we called “Passive house in France” : rouby hemmerlé architects think about a high quality architecture, they are looking for sobriety, sincerity and reliability. The land is located in a small hilly town in Ardèche, France. The main intention is to merge the house in the titled landscape. The long structure inserts into the topography. In the living spaces the views of the orchards and the Hills are unobstructed. The basement level is organized in order to limit excavation. At the ground floor there is the main living space, where there are the kitchen, the living room and the bedroom. The cantilevered space has two bedrooms and another bathroom and overhangs the Terrace. The structure is made of wood frame with a concrete base. The lights entries are facing the South in order to enjoy passive inputs. The thermal performance (wall, floor and triple glazing) coupled with double-flow ventilation and geothermal solutions are implemented to achieve the objectives of a passive construction.
