Agathē builds to the certified Passivhaus standard across the Northern Beaches — surf coast, harbour side and peninsula — engineered for the exposure that defines how the Northern Beaches live.
A certified Passivhaus is measured, not promised. An airtight, highly insulated envelope with continuous filtered fresh air keeps the whole home within a few degrees year-round — without leaning on air conditioning. The result is a home that is quiet, free of draughts and condensation, dramatically cheaper to run, and independently certified to perform exactly as designed.
The Northern Beaches are our home ground — we build healthy, high-performance homes here every week, and Passivhaus is that work taken to its certified conclusion. The conditions are the reason: salt-laden onshore winds from Queenscliff to Palm Beach, humid harbour air around Clontarf, Seaforth and Balgowlah Heights, bushland moisture on the Avalon escarpment, and a beloved older housing stock that answers all of it with single glazing and hope. A certified Passivhaus is engineered for exactly this coast — airtight envelopes that keep wind-driven moisture out of the fabric, independently certified windows that survive the exposure and hold the views, and continuous filtered ventilation that keeps homes dry, fresh and mould-free through the stickiest February. Led by a Certified Passivhaus Tradesperson, with structured pre-construction behind every build.
