HEALTHY HOMES ON SYDNEY'S NORTHERN BEACHES
OUR SERVICES
Agathē takes a whole-home approach to healthy building, tailored to the unique conditions of coastal Northern Beaches living. Whether you're concerned about indoor air quality, mould prevention, thermal comfort, or the hidden chemicals in everyday building materials, we have the expertise and certification to address it. Our services include low-tox material selection, moisture and ventilation design, thermal performance, low EMF considerations, and sustainable building practices — allowing you to create a home that genuinely nourishes your family.
A LOCAL BUSINESS
Based on Sydney's Northern Beaches, Agathē proudly serves families across the Northern Beaches and North Shore. As your local Healthy Homes specialists, we understand the unique challenges of building in a coastal environment — salt air, humidity, and the conditions that make moisture and mould a real concern here. Our deep knowledge of the local landscape means we deliver solutions that perform for this specific climate, not just on paper.
CLIENT CENTRIC APPROACH
At AGATHĒ, your satisfaction is at the heart of every granny flat we create. From the first consultation to the final handover, we keep communication clear and consistent, ensuring you're informed and confident at every stage. With meticulous attention to detail and a tailored approach, we design and build granny flats that suit your North Shore property, family needs, and budget—making the journey from concept to completion smooth, enjoyable, and rewarding. We navigate council approvals, manage compliance requirements, and coordinate all trades so you can focus on the exciting possibilities your new space will bring.
With years of experience, AGATHĒ has built a strong reputation for exceptional craftsmanship, thoughtful design, and outstanding customer service. Our team of skilled tradespeople, talented designers, and dedicated project managers work together to deliver results that exceed expectations. From the initial consultation to the final finishing touches, we prioritise clear communication, meticulous attention to detail, and superior workmanship in every granny flat we create. Each dwelling is built to the same exacting standards as our luxury homes—because quality should never be compromised, regardless of scale.
