Agathē creates healthy, high-performance homes in Bilgola Plateau, bringing building science, low-tox craftsmanship, and Northern Beaches expertise to build spaces that genuinely support the way your family lives.
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.
Perched on the elevated headland between Newport and Avalon Beach, Bilgola Plateau is one of the Northern Beaches' most peaceful and sought-after pockets — clifftop living, leafy streets, and sweeping ocean views. But homes in this location face real environmental pressures: salt-laden air, coastal humidity, and strong prevailing winds that accelerate moisture ingress and material degradation over time. These are exactly the conditions a Healthy Homes approach is built for. Whether you're looking to address hidden mould, improve indoor air quality, upgrade to low-tox materials, or build a high-performance home that works with the coastal environment rather than against it — we know how to get it right in Bilgola Plateau.
