AGATHĒ builds custom granny flats across Sydney's Northern Beaches that marry architectural elegance with everyday 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 Northern Beaches property holds untapped potential. At AGATHĒ, we turn that potential into beautifully crafted reality — designing and building custom granny flats across Sydney's Northern Beaches that marry architectural elegance with everyday functionality, from first sketch to final handover. We design and build self-contained dwellings that complement your existing home, working closely with you every step of the way — whether for multigenerational living, guest accommodation, a home office, or rental income.
