A draughty cottage in Blackburn North, Victoria, was transformed into a modern Passivehouse-standard home by a builder and landscape architect.

Using recycled materials and repurposed planting, the retrofit achieved outstanding energy efficiency and airtightness, exceeding EnerPHit standards. 

Featured on ABC’s Grand Designs Transformations, the 150 m² timber-constructed home includes high-performance insulation, efficient ventilation, and ecological features like rainwater harvesting. 

Key upgrades reduced heating and cooling needs while improving comfort.

The project was completed in 2023 with a focus on sustainable design, collaboration, and modern functionality, creating a comfortable, energy-efficient home with a garden oasis.
