Single Dwelling
Passivhaus Plus

Our clients were first and foremost seeking a high-performing certified Passivhaus to ensure their health and comfort. The owners approached North South Homes to execute their dream of building and living in a Passivhaus. To them, a Passivhaus would answer their needs to have a home that encompasses not only sustainable building practices and running costs but also allows them year round comfort and, in particular, a healthy living environment.

  • Custom joinery, custom cladding for facade, having clients completely on board with Passvhaus building practices

  • Challenges - PH Consultant Designer was overloaded with work, we struggled to get the PHPP Information in a timely manner. Lessons - Architect and Designers should not be doing PHPP consulting at the same time as designing. Hire an external PHPP Consultant, always.
