AGATHĒ builds custom granny flats throughout Sydney's North Shore that marry architectural elegance with versatile functionality — self-contained spaces that add real value and flexibility to 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.
Your property holds untapped potential. At AGATHĒ, we transform that vision into reality — creating custom granny flats throughout Sydney's North Shore that marry architectural elegance with versatile functionality, from your first sketch to the moment you welcome your first occupant.
