As a growing family, the clients wanted to add a two story addition, comprised of two new bedroom, a bathroom, a dining room, a kitchen and a laundry room. They wished to keep the existing house intact so as to keep within their budget.

As they are expecting to co-live with aging in place parents, they wished to preserve to consolidate the footprint so as to keep development opportunities at the back of the lot for a future DADU.

The design was driven by the clients’ passion for ecological solutions. Demolition of the existing house was kept to a minimal. The extra thick walls, the double insulated attic, the orientation of the house towards the South facade, the use of cross ventilation and mud room and porch designs to live outside as much as the year as possible and to only rely on the heat pump during acute weather events all contribute to making this house a high thermally performing structure.

From a design perspective, the historical precedent of the range house typology of the 1950’s drove some of the project’s perks, by re-interpretating some of the features such as the glass block or textures and patterns of the 50’s.
