AGATHĒ builds quality granny flats in Kenthurst, bringing expert craftsmanship and a genuine appreciation for this spacious, semi-rural 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.
Kenthurst is one of Sydney's most unique and sought-after pockets — a semi-rural community in the Hills District where properties sit on large acreage blocks surrounded by bushland, orchards, and open space. It's a place where families come to breathe, with a strong community feel, excellent local schools including Hills Grammar and Marian College, and a way of life that's hard to find anywhere closer to the city. With so much land to work with, Kenthurst properties are naturally well-suited to a beautifully designed granny flat. Whether you want a comfortable, independent space for ageing parents, a private retreat for adult children, a peaceful home office set well away from the main house, or a quality rental that makes the most of your land — we'll design and build something that fits the scale, character, and spirit of Kenthurst, and adds genuine, lasting value to your property.
