AGATHĒ delivers healthy, high-performance homes in Kirribilli, combining building science, low-tox craftsmanship and North Shore expertise to create homes that support your family's wellbeing in one of Sydney's oldest harbourside villages.
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.
Kirribilli is one of Sydney's oldest harbourside suburbs, and its Victorian terraces and Federation homes sit close together on tight blocks with the water never far away. Heritage character is why people love it here, and it comes with heritage realities: original subfloors with minimal ventilation, shared walls that limit where air can move, and harbour humidity working on buildings that predate any notion of moisture design. Renovating in Kirribilli means improving how a home breathes without losing what makes it Kirribilli. That is exactly the work a Healthy Homes approach is built for: air quality, moisture control and low-tox materials, delivered with the care a hundred-year-old home deserves.
