Located opposite the Gulf of Hossegor, the house previously opened on a single facade, cut off from a remarkable site because of its hermetic disposition. In addition to creating a winter garden, the owners wanted to adapt it to contemporary uses with an optimized supply of natural light and the establishment of a direct link with nature. The most delicate task in intervening on this 1960s building, without distorting its cachet, was to succeed in creating an extension that did not appear as an added element. It had to be part of a coherent whole both functionally and formally. While respecting the lines of the wooden facade that it reveals, a ribbon of concrete draws a relationship with the natural world. Following the model of the Japanese house's external passageways, “the Engawa”, this transitional space creates an original relationship with the landscape, which becomes an integral part of the living space. Through skilful landscaping, the surroundings have been modelled to accentuate this effect of projection on to the exterior.
