Chalet ‘Dag’ is a project designed by Chevallier Architectes and is located in Chamonix-Mont-Blanc, France. This cottage was originally a summer residence, like many others in Chamonix, and was therefore not insulated for winter use. No upgrades had been done since its construction approximately 70 years ago. The upper level was used only as an attic and the lowest level as a garage, with only the middle level used as living space. The firm’s mission was to make all existing floor space liveable, using the best available insulation solutions.
