Granny Flats

Wahroonga

AGATHĒ builds quality granny flats in Wahroonga, bringing expert craftsmanship and Upper North Shore knowledge to create spaces that add value and work for your lifestyle.

Granny Flats, the Scandi Way

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.
