For building this Whistler custom home, we used a combination of Insulated Concrete Form (ICF) for the foundation and Structural Insulated Panel (SIP) for the walls. This allowed us to create a highly sustainable build that is both energy efficient and capable to withstand Whistler’s climate. This will offer substantial energy cost savings and comfortable living for many years. This sustainable design and construction offers year-round comfort, staying cozy during the coldest winters and cool during the hottest summers.
