Project Description
High performance is for everyone, not just for high-end custom homes. The house achieved Passive House certification at a price point comparable to average construction costs in British Columbia. The house includes a suite, increasing the community’s available housing options while helping to offset overall costs for the owners.
The owners and renters will both benefit from Passive House features such as exemplary comfort and air quality, sound separation, improved occupant health, and low operating costs. The design followed a simple but iconic residential building form, which helped to achieve our passive house goals while keeping the home affordable. The cedar-lined wing walls are visually striking and draw attention to the thickness of the energy efficient wall assemblies, and aid in shading in the summer. Indoor-outdoor connection is a key element of this design and the great room opens up to the outdoors with full height windows and large double doors that provide connection to the patio and yard beyond.
