san francisco bay area landscape design and installation

Welcome to
Koch & Associates

For over 40 years, we’ve been the Bay Area’s trusted landscape designers and contractors.

Founded in 1978, Koch & Associates is one of the Bay Area’s longest-running landscape construction firms. Our master-builder approach offers clients one source of contact for landscape installation. This collaboration between the landscape designer and landscape contractor ensures that the integrity of the design will be maintained as it moves throughout each phase of implementation.

At Koch & Associates, Inc., we begin each outdoor landscape project with a close collaboration between the homeowner and the landscape designer. Combining a spirited discovery with a thorough site analysis allows for a unique project that incorporates the client’s personality and interests, while enhancing the site’s natural harmony.
