Chalet Chantemerle

Saint-Chaffrey, France

10 FR Chantemerle picture01 1 | 10 FR Chantemerle picture01
An alliance of tradtional times and the modern age for optimal comfort – a refined and cozy vision of building in the mountains.
Design: The chalet is a realization of a series offered by a French wood construction company, customized by an architect. The traditional roof truss with distinct lines and a modern floor plan is a trademark of the series. The chalets primarily serve as vacation homes rented by tourists.

Wood: The wood frame walls are completely airtight. Oversized girder diameters were used for the visible structural system, showing hand-made details in some parts. Some beams consist of old massive timber. The construction company only uses local, PEFC-certified wood, primarily larch. Larch is a typical kind of timber for the Hautes-Alpes region, seeing that the wood is robust and resistant to rot. Larch is used for a variety of purposes: as massive beams with traditional surface treatment for the visible structural system, as untreated slats for the facade, as brushed slats for the interior walls, or as the base material for the interior finishing.

Energy: The excellent energy-related qualities of wood help the chalets to meet the standards of the French Thermal Regulation RT 2012 (upper limit of 50 kWh/m²a) and certificates such as BBC-Effinergie®.
