What people are saying…

  • "We have been living in our Passive House for about a year and a half now, and it has fundamentally changed our standard of comfort. It truly is a haven in every season. Whether it’s summer or winter, the house maintains a perfectly pleasant temperature and an excellent level of quietness. We've got a train line near us but you wouldn't realise that inside the house. What surprised us most was the air quality. Thanks to the HRV system, our home stays incredibly clean, the filters keep out everything from general dust to bushfire smoke. Because of this the air quality indoors is always high and there's always fresh air. H4 Living were great at taking our requirements and loose ideas and making it a reality. Our family and visitors always comment on how much they love staying here. It's well built, beautiful and functional for our particular needs."

    —Ren and Ranjani
