Our Approach

At Pistils Landscape Design + Build, we believe that the outdoor spaces we inhabit are central to our experiences and quality of life.

Whether collaborating with a client directly, or partnering with an architect or designer, our greatest joy comes from realizing the inherent potential of a landscape.

With an abiding passion for Pacific Northwest flora, climate and geography, our team knows a successful design begins with a deep understanding of how the built can harmoniously integrate with its natural surroundings. Respecting the “genius of place” -- working with, rather than against, the unique character of each site -- informs all aspects of our design and installation work.

Our approach is highly collaborative. We actively engage with our clients, learning about their lifestyles and goals for their outdoor spaces, brainstorming together to ensure the end result is uniquely theirs. As a business, we’re committed to engaging with our clients in a way that is both ethical and honest, producing a result that is of the highest quality.

As a design-build firm, Pistils includes both innovative designers as well expert installers.

Our design team, led by a licensed landscape architect, achieves the needs of our clients in thoughtful, inventive ways. With an unmatched knowledge of natural materials and flora native to the region, our designers are well-suited to take on any project in the Pacific Northwest.

With highly skilled masons, carpenters, metalsmiths and plant specialists on-board, our installation team is fully equipped to handle all elements of landscape construction. Our project managers overlap regularly with our designers, which assures that the nuances developed during the design are realized during installation.

Founded in 2001 alongside our sister business, Pistils Nursery, our projects range from small urban residences to expansive rural landscapes, as well as select commercial sites. While design-build is our primary focus, we also welcome design-only and installation-only projects.

Pistils Landscape Design is committed to ethical and non-discriminatory hiring, and we believe every member of our staff, from landscape architects to installers, deserves a living wage. In all of our projects, we consider our environmental impact, striving to make decisions that put sustainability first.

Behind each of our designs and installations is a passion to creatively explore the graceful interchange of form, habitable space and the natural world.
