Rosebush Urban Reno

Natalie is a leading expert in Passive House design and construction, and after our first meeting with her we knew we were in good hands. She made it her priority to understand our priorities. We have a beautiful, energy efficient home. It’s warm in the winter, cool in the summer and uses a fraction of the energy of a comparable sized house. We highly recommend Natalie; her patient, calm demeanor and sage expert advice will be reassuring to anyone. ~ Stephen MacDonald and Tara Anstey

  • This project is one of the first passive-house level renovations in Canada- renovations present a challenge because existing assemblies generally do not meet passive-house standards and the design of the existing structure may not accommodate the principles of passive building.
  • Keeping the structure and certain architectural elements of the existing home helped to reduce costs and speed construction, while maintaining a relationship to the previous building and the character of the neighborhood.
  • Using careful detailing and assemblies, the home achieved a passive-house level of airtightness even though it is a renovation- the foundation/wall interface is particularly difficult in this kind of project!
  • With a tight urban lot and a south-side condition, the window placement is carefully considered to maximize solar gains in the critical rooms while maintaining privacy and a friendly street face.
