AGATHĒ builds quality granny flats in Glenhaven, bringing expert craftsmanship and a genuine appreciation for this prestigious, tightly held community to create spaces that add real value and work beautifully for the way your family lives.
At AGATHĒ, a granny flat is never a budget afterthought in the backyard. It's a Scandinavian-designed, high-performance home in miniature — built with the same building science, natural light, low-tox materials, and considered craftsmanship as our Scandi homes. Beautiful, healthy, and built to last.
We turn generous backyard spaces into beautiful, self-contained homes — thoughtfully designed, carefully finished, and built to sit naturally alongside the character of your existing home. The result is a practical, elegant space for ageing parents, adult children, a quiet home office, or quality rental income.
The name says it all — Glenhaven really is a haven. Tucked away in Sydney's Hills District, this prestigious semi-rural suburb is known for its large, beautifully kept homes on generous blocks, its abundance of flora and fauna, and a quiet, country village feel that's rare to find this close to the city. It's a suburb where people put down deep roots — once families find their way here, they rarely leave. With properties sitting on some of the most spacious land in the Hills District, there's often real opportunity to make the most of what you have with a well-designed granny flat. Whether you're looking to create a comfortable, independent space for ageing parents, a private retreat for adult children, a dedicated home office set well away from the main house, or a quality rental that complements your property — we'll design and build something that sits beautifully in Glenhaven and adds genuine, lasting value to your home.
