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.
