GREENOAKS ATHERTON CA

A family treehouse of sorts.

Greenoaks is a family home in Atherton, California — a residence conceived as a treehouse of sorts, where children and adults alike find themselves drawn into the landscape. Studio Collins Weir collaborated closely with architecture firm Aidlin Darling Design and landscape architects Surface Design to create a home that lives as comfortably indoors as out.

The project received the 2025 IIDA Northern California Design Award, recognizing its contribution to residential interior design in the Bay Area. Rooted in the particular spirit of Northern California family living, Greenoaks balances refined material choices with the warmth and ease of a home built to be truly inhabited.
