The First Now House



The Now House project has turned a 60-year-old WWII house into a near zero energy home—one that produces almost as much energy as it uses.

The first Now House is located in Topham Park, Toronto. The home is a 1200 square foot, 1 1/2 storey, detached structure in a community of 200 similar wartime homes. It was built in 1946 from plans available from CMHC.


The Now House Project is a collaboration of designers, architects, engineers, homeowners and sustainable building experts led by Lorraine Gauthier of the design consultancy Work Worth Doing.

Now House is proud to be one of the winners of CMHC’s EQuilibrium Sustainable Housing Demonstration Initiative. It was partially funded by Canada Mortgage and Housing Corporation. Platinum sponsorship by RBC Royal Bank.


The Retrofit Process

To achieve our goal of a near zero energy retrofit we made the following changes to this home. As all existing houses have a unique set of conditions and characteristics, the application of the Now House process to another house would produce different design specifications. What follows is not a prescription for the near zero retrofit of all homes.
