AGATHĒ delivers healthy, high-performance homes in Mosman, combining building science, low-tox craftsmanship and North Shore expertise to create homes that support your family's wellbeing in one of Sydney's most admired harbour suburbs.
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.
Mosman's streets hold some of Sydney's finest Federation and Edwardian homes, set on slopes that fall away to Balmoral, Chinamans Beach and the harbour. The setting is superb, and it is also demanding: sea air and harbour humidity work on solid-brick walls built without modern moisture protection, mature fig and gum canopy keeps southern aspects in shade for much of winter, and sloping blocks leave subfloors damp and still. Renovating here is about making what's behind the walls match the quality of the street presence. A Healthy Homes approach addresses air, moisture and materials as carefully as joinery and finishes, so a Mosman home performs as beautifully as it presents.
