Discover what it means to live in a home that actively works for your health — thoughtful material choices, ventilation design, and considered finishes where indoor air quality, thermal comfort, and low-tox living come together seamlessly with beautiful, functional design.
Tucked along the northern shores of Middle Harbour, Clontarf is one of the Northern Beaches' most tightly held and picturesque waterfront suburbs. Homes here enjoy stunning harbour views and proximity to the water — but that same waterfront setting brings with it some of the most demanding conditions for building performance. Salt air, tidal humidity, and the constant moisture influence of Middle Harbour accelerate deterioration in building materials, promote mould growth behind walls, and compromise indoor air quality in ways that are easy to overlook. A Healthy Homes approach is built precisely for environments like Clontarf — addressing what you can't see as carefully as what you can, so your home remains a healthy, high-performing sanctuary for your family for decades to come.
