AGATHĒ delivers healthy, high-performance homes in Castle Cove, combining building science, low-tox craftsmanship and North Shore expertise to create homes that support your family's wellbeing on the bush slopes above Middle Harbour.
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.
Castle Cove's mid-century homes step down steep bush blocks above Middle Harbour, many with the big glass walls and suspended floors that make the most of the view. Those same features define the suburb's building challenges: single-glazed expanses that stream with condensation on winter mornings, suspended floors over shaded, damp slopes, and southern aspects that see little direct sun beneath the tree canopy. The bones of these houses are often excellent and worth keeping. A Healthy Homes approach upgrades how they perform: glazing and thermal comfort, subfloor moisture and ventilation, and low-tox materials, so a home with a remarkable outlook is just as remarkable to breathe in.
