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.
Your property holds more potential than you might think. At AGATHĒ, we turn that possibility into something real — building custom granny flats across Sydney's Hills District that are as beautiful as they are practical, from the very first conversation to the day you hand over the keys. We design and build self-contained homes that feel like a natural extension of your property, working closely with you every step of the way — whether you need a comfortable space for ageing parents, a retreat for adult children, a quiet home office, or a rental that generates real income.
AGATHĒ builds custom granny flats that turn Hills District homes into places that truly work for the people living in them. Whatever you have in mind — a private space for family, a creative studio, or an investment that pays for itself — we bring it to life with care and skill. We work with talented local architects and experienced tradespeople to make sure every build is done right, blending beautifully with your existing home and fitting naturally into the neighbourhood around it.
AGATHĒ has worked across Sydney's premium residential areas for years, and we're proud to call the Hills District part of our patch. We know the area well — the streets, the homes, the community — and we understand what it takes to build here. From navigating council approvals to respecting the feel of the neighbourhood, we handle the details so you don't have to. Every project we take on in the Hills District is approached with the same care and commitment we'd bring to our own home.
