At ROCHE+ROCHE Landscape Architecture, we create quiet landscapes of subtle beauty. Our landscapes are designed to enhance the restorative effect of a subtly shifting natural environment, a phenomenon known as “soft fascination.” We practice the mantra of ‘unify…simplify…amplify’, editing out the unnecessary and celebrating the distinctive and powerful.

We invite our clients to engage in a design relationship that begins the day we meet, and continues through design, construction and beyond, to ensure the long-term success of their landscape. We take the time to understand the inherent character of each site, studying the existing features, views, drainage patterns, climate, soils and vegetation.  Then we apply sound environmental practices to ensure sustainable designs that create habitat and encourage beneficial wildlife. We collaborate with talented architects, interior designers, engineers and builders to create seamless environments that reflect the architecture and respect the site. We bring our rural contemporary vision to projects throughout Northern California, ranging from residential estates to wineries and resorts.
