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.
Longueville occupies a quiet peninsula reaching into the Lane Cove River, its streets lined with grand older homes under a mature canopy that has been growing for a century. Riverside humidity, shaded gardens and sandstone foundations are part of the suburb's character, and they are also the classic ingredients for subfloor damp, musty rooms and condensation in winter. Homes here tend to be substantial, much-loved and renovated in stages across generations, which leaves plenty of places for moisture problems to hide between the layers. A Healthy Homes approach brings it back to one coherent building: clear moisture pathways, ventilation that works with the river climate, and materials chosen for the decades ahead.
