Meeniyan Project
Residential: Single Dwelling
Passivhaus Plus Certification
Meeniyan, VIC, 2023
This is single-storey, four-bedroom home was completed in 2023. The clients deliberately chose North South Homes for their expertise with the Passivhaus Standard. They were in a situation where they were unable to achieve the level of detail and performance needed for airtightness and insulation. The project became a design-and-build process guided by PHPP science-backed modelling.

The team set out to adapt the original design to align with the Passivhaus Standard while keeping within the client’s budget. With a few smart adjustments—such as incorporating scissor trusses—the project was able to achieve this balance successfully.
