About this home

Oceana Passivhaus is a coastal home in its final stages of construction, targeting Passivhaus certification per the Passive House Institute standard. Construction finishes in May with more photos to come before open day.

Walking through a high-performance home at this stage is powerful because the house has started to “settle” into how it feels. Nearing winter in the Illawarra, you’ll notice the absence of draughts, the consistency of temperature from room to room, and the overall comfort. The windows are in, the envelope is sealed, and the space already holds itself differently to a standard build.

This tour is an opportunity to ask the builder what was prioritised, what trade-offs were made, how airtightness was achieved, and what lessons were learned along the way. You can talk through whether certification matters to you, how the ventilation system works, and how early decisions in pre-construction shaped comfort and energy use long before we walked on site.

For someone interested in sustainable living, seeing Oceana during fit-out offers something rare: a chance to connect performance to lived experience before the home is styled and furnished. You can feel how the building behaves as the seasons shift, and you can explore whether this level of comfort, health and energy efficiency aligns with your own values. If you’re even considering building or renovating in the coming years, stepping inside a soon-to-be Passivhaus like this while it’s still in progress can clarify what actually matters to you and your family.
