The Alps often block. Under the blanket of snow, the relentless rock hardness defies architecture: time is not taken, it is eternity that opposes the fragility of human settlements. And yet contemporary architecture has its place in an old mountain hamlet. This is amply demonstrated by the Mineral Lodge in Savoy at 1200 m altitude.The site offers excellent views of the surrounding mountains and valleys, the project uses, says perhaps this fascinating landscape. Here it is build with tact.In a majestic natural theater building is an act that must interact with the geology, its history frozen in the presence of mineral immemorial movements.Rock fixed time. Building becomes the time when the human encounter geological time. The Mineral Lodge , hut of stone and rock, is a non-standard cottage compared to current production as compared to the segment of luxury chalet, which thrives in the Alps. The hamlet of Villaroger the strict rules of constructiveness and architectural integration, suggested, with the ruins of a device from a farmhouse wall mitoyennté an existing cottage, an opportunity for dialogue between the vernacular architecture and contemporary aspiration to live with the objective of sustainable development enabled by recent technological developments.A physical link has been established with the adjoining family cottage as high vertical fault. Inside the new cottage Mineral Lodge , on three levels, is left exposed the stone wall that was blind gable cottage. The challenge was to make the emergence of Mineral Lodge pre-existing ruin, to propose a conversion of these traces: in a way it was to happen to the architecture where there was only construction.The stone farmhouse was not rebuilt: we could definitely be locked within the past you had to mean a new era compared to that of dry stone walls, proceed literally as figuratively . This is the role that takes the wooden cube which projects from the glass stay upstairs. He became strong emblem of the cottage, and made landmark is reminiscent dryers cantilevered remaining on old Tarentaise chalets.The gently-taking views of the landscape and the sequences of inner journey guided the definition of spaces. The first floor hosts a variety of systematic cross prospects outward and spaces are linked with fluidity, but no hallway gallery at the intersection of the geometries is the junction between the living room and media room.The height limit imposed sparked a game levels enriching spatial proposition walkways allow stairs to catch the differences in levels between the new flooring and those of the old cottage where two rooms were built. The kitchen unfolds at the foot of the large volume and creates, lit by a glass roof. Playing an important role in the project, the roof is made of reinforced concrete, avoiding the inevitable project wood frame that feels obliged to sacrifice brand new chalet. It is a jacket for a more flexible distribution of spaces.The use of stone as a coating and not walls or structural columns are left with the mass of the main staircase, where a close eye faster than the various windows as deadly spread randomly can not conceal that includes a structure reinforced concrete. The effect of surface sees increased. In addition, this volume is not only one of the stairs but it houses the windows of a room on the third floor. The mapping of the exterior and the interior is abolished. It is indeed here a characteristic of traditional chalet where it is not easy to guess what kind of room (bedroom, living room, kitchen, ...) is behind a window. This high unit volume and varied both conceals its functions and is required to form itself. The grooved larch box just to stay there built with precision, even marrying the irregularity of the stone. With this interaction, fundamentally different materials set them a subtle connection.Constraints sismicitié and protection in an avalanche impacting the south side, led to structural choices ensure robust and sustainable. The choice of deep geothermal drilling in the rock gives the Mineral Lodge energy efficiency and part of a sustainable development approach, while remaining invisible.Finally, as inserted in a green dry stone chalet stands a short distance from walls without touching the past, creating an in-between or intermediate space filter between new and old walls largely glazed facades. This interstitial space maintains a productive tension between past and present. The Mineral Lodgeestablishes a constant oscillation between the past and the present. It offers an architectural framework without express traditionalism. Unlike the conventional cottage where the window sizes are dictated by the constraints of thermal insulation, it provides generous natural light. In the French Alps, a traditional expression architecture has become a marketing slogan devoid of any meaning or interest. The Mineral Lodge is a rare attempt to contradict this nostalgic favorite at work everywhere in Savoy.
