This residence for a pediatrician and his family is located in a part of Yamagata Prefecture that receives heavy snow. The design began with the idea of using a rock garden on the adjacent property, where the client’s parents live, as “borrowed scenery.” The distinctive massive concrete façade utilizes exterior insulation to ensure a comfortable interior temperature even in mid-winter, and the brise-soleil and insulated wood-framed windows further adapt the home to its snowy environment.
