Agathē delivers healthy, high-performance homes in Balgowlah Heights, combining building science, low-tox craftsmanship, and Northern Beaches expertise to create homes 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 a ridge up to 80 metres above North Harbour and Middle Harbour, Balgowlah Heights is one of the Northern Beaches' most prized and characterful suburbs — low-density living, panoramic harbour views, and streets lined with a mix of mid-twentieth century villas and architecturally considered sandstone and timber homes. That elevated position and harbour proximity is breathtaking, but it also means homes here face a persistent combination of harbour humidity, salt air exposure, and the kind of moisture-laden air that works its way into building fabric quietly and over time. Many of the established homes in Balgowlah Heights were built in eras when ventilation and moisture management simply weren't design priorities. Our Healthy Homes approach brings those homes — and their families — up to a standard that matches the quality of the suburb itself.
