We were looking for a landscape architect who could provide a design that would complement our property while also meeting our design aesthetic and functional needs. Wow! > > Warren’s design exceeded our expectations, not only on the page, but in fully realized execution. As I sit surveying our yard I can honestly say that Warren’s design has grace, proportion, and nuance. We could not be happier. > > George & Diane **★★★★★ — J. Briscoe, Sept. 2018** > My wife and I bought a home in Marin Country Club in 2002, one with a large and flat lot. The part of the property not occupied by the house was late-1950s concrete and lawn, and we soon removed most of the concrete and redid the rest. We endured the makeover for ten years, but were not happy with it. > > We learned of Warren Simmonds through word of mouth, and of course his great landscape work. > > Warren listened. Warren was patient, infinitely patient. In time, in much patient time from Warren, we went with his proposal, and we have never been happier with an architect. > > He also introduced us to several landscape contractors, we went with one, and he and Warren worked like hand in glove. We have had many pleasant experiences with architects before (never mind the less-than-pleasant ones) but never more than with Warren. > > And the landscape Warren and the contractor produced could not make us happier. On budget, on time, and far more beautiful than we could envision from two-dimensional drawings. **★★★★★ — CK Landscape, March 2018** > I have worked with Warren and Simmons and Associates on a few projects and they are INCREDIBLE to work with. Great design elements, thoughtful process, and top notch dedication. As a family landscape firm we love working with great people and the Simmonds and Associates team is just that. We highly recommend Simmonds and Associates. **★★★★★ — Magali Salomon, Dec. 2017** > We hired Simmonds & Associates in the spring 2017 for a complete backyard remodel on a hillside. They were able to transpose our ideas into concrete plans and come up with several appealing designs. They handled everything from the design concept to execution. We were very happy with the landscape contractor who executed on the plans, which was selected by Simmonds & Associates. Overall, we love our new, expansive backyard. Well worth it! **Comment from Simmonds & Associates, Inc.:** > Thank you, Magali! It was great working with you and Jim to realize your dreams for your landscape remodel! Hope you enjoy your yard for many years to come. **★★★★★ — Zeke Sevier, Nov. 2017** > The team at Simmonds and Associates are professional and knowledgeable in their field. They provide outstanding landscape design services with customer collaboration and attention to detail. It is always a pleasure to work with this company. **Comment from Simmonds & Associates, Inc.:** > Thank you, Zeke! We love collaboration. It is a pleasure to work with you as well! **★★★★★ — Linda Novy, Oct. 2017** > Simmonds & Associates create landscapes that are beautiful, functional, and well suited for each property. I have worked with them for the last 7 years on a homeowners' association project and am dazzled by the colorful and unique combinations of plants, and their thoughtful placement in the landscape. This particular client wanted color and the creation of pollinator habitat. It is so rewarding to walk through their grounds, and see the hummingbirds and other bird species, honey bees, butterflies, and all manner of pollinators thriving, not to mention the joy this brings to the residents. As a landscape manager, I appreciate the professionalism that Simmonds & Associates brings to each client and in each vendor relationship. The result: brilliant design, thriving landscapes, and great team work! **Comment from Simmonds & Associates, Inc.:** > Thank you so much, Linda. It is always a pleasure working with you as well! **★★★★ — Donna Abrahamson, Aug. 2017** > Warren was very professional and had the patience to help us through every step of the way! He's a delightful person. **★★★★ — Craig Waldman, Dec. 2016** > First class organization. Took a concept to greatly enhance our usable space, add a pool, landscaping, BBQ, etc etc etc and made it happen. Handled permitting issues, used the space brilliantly, and made great plant choices after hearing our preferences. Recommended . **★★★★★ — Sydney Joyner, Nov. 2016** > Warren and Alex designed our project and did a wonderful job. It was a large, complex landscape project that included many different planting areas, microclimates, retaining walls, and a living wall. They were imaginative and professional throughout. We highly recommend them. **Comment from Simmonds & Associates, Inc.:** > Sydney, > Thank you so much. You were wonderful clients to work with. The 4-way team of Client, Architect, Landscape Architect and Contractor, when all working together, makes for the best of outcomes. **★★★★★ — Michael Harrold, Feb. 2016** > I used Simmonds and Associates for a major landscape remodel at my home in San Mateo. Warren and his staff were easy to work with and very responsive to our questions. After working through many possible options for our landscaping Warren and his staff developed a plan that we were happy with. They also helped us find a landscaping contractor and supervised the installation work. Our garden has had 2 years to grow in and looks fantastic. We get many compliments from our neighbors and we are very happy with the design. Highly recommended. **★★★★★ — Rebecca Bach, Feb. 2016** > I've had the pleasure of working with Simmonds and Associates for the past nine months restoring the landscape of a classic Gwathmey Siegel Residence in Belvedere, California. Our project is complex involving six levels of steep gradient, compact spaces, and a mass of very tall walls and windows. It's been an easy process - they understood exactly what we needed, drawings were produced quickly, and their fees were extremely reasonable. They were also efficient with our time, quick to follow up and thorough with their research. I highly recommend their office and hope I have an opportunity to work with them again on another project. **★★★★★ — pollybaney, Dec. 2015** > Warren Simmonds was recommended to me by my structural engineer who was working on an extensive retaining wall project in my backyard. When it came time to put the yard back together, Warren gave me a completely fresh look that I love, and on which I get absolutely tons of compliments. The space looks larger and now maximizes the great views, plus it is much more water efficient now. Warren is that rare professional who combines practicality (i.e., knows his materials and how to get a "look" while staying on budget), with creativity (coming up with solutions to problem areas, and adding fresh, great design). Additionally, he has fantastic resources to recommend in the community. I used all of his resources, and am 100% satisfied with the work product and attention to budget.

The front lawn ran from the house to the curb, and the landscape offered no sense of arrival, or transition from public to private space. We reduced the size of the lawn by approximately 60 percent. Simultaneously, we choreographed a sense of entrance. From the sidewalk, the old brick path leads throug… - [Modern Tiburon Living](https://www.houzz.com/hznb/projects/modern-tiburon-living-pj-vj~2471764) - Location: Tiburon, CA - Photos: 15 - Description: Crome provided concept and schematic design services, planning and pre-construction services, permit/construction drawings and construction administration.

When our clients purchased the property in 2009, they found the house and landscape to be in need of a major updating. Not only did the house receive a complete make-over, but the landscape was brought into the 21st century also. A new pool, with energy-saving cover, a patio with an outdoor fireplace, a sport court, are some of the amenities. Fine detailing in fences, gates, planters and… - [Mill Valley Hillside Garden](https://www.houzz.com/hznb/projects/mill-valley-hillside-garden-pj-vj~2635268) - Location: Mill Valley, CA - Photos: 26 - [2200 Pacific](https://www.houzz.com/hznb/projects/2200-pacific-pj-vj~145725) - Location: San Francisco, CA - Photos: 12 - Description: In 2011 we won a small competition for the 2200 Pacific Homeowners Association to transform their landscape into a contemporary, elegant entry to a 1960’s Modern, 12 story building. The design brief described a desire to create a “wow” factor while dealing with large vents in the street-side planters that take up over 50 % of the space, and cannot be blocked! Stainless steel trays hover above the vents and hold a soft, naturalistic planting, which contrasts with a new polished black granite wall… - [A Contemporary Farmhouse](https://www.houzz.com/hznb/projects/a-contemporary-farmhouse-pj-vj~834894) - Location: Kentfield, CA - Photos: 44 - Description: This garden is featured on the Ross Garden Tour 2018!

Working with the existing landform, the entry to the house and all patios were rebuilt with bluestone paving, which is complimented by hand-selected g… - [An East Bay Garden](https://www.houzz.com/hznb/projects/an-east-bay-garden-pj-vj~79882) - Location: Piedmont, CA - Photos: 24 - Description: This property has a wonderful juxtaposition of modern and traditional elements, which are unified by a natural planting scheme. Although the house is traditional, the client desired some contemporary elements, enabling us to introduce rusted steel fences and arbors, black granite for the barbeque counter, and black African slate for the main terrace. An existing brick retaining wall was saved and forms the backdrop for a long fountain with two stone water sources.

The large expanse of driveway paving was reduce… - [A Larkspur Garden](https://www.houzz.com/hznb/projects/a-larkspur-garden-pj-vj~200884) - Location: Larkspur, CA - Photos: 16 - Description: The front garden of this traditional-style house was re-imagined to remove the front lawn by sheet mulching. The lawn was converted to a California native garden. The back garden takes on a formal arrangement of lawn and planting beds,and incorporates a linear water feature that begins in a basin in the patio, flows along the patio, down the stairs to a pond. The formality of the design is juxtaposed with a loose planting of small trees, shrubs and perennials, interspersed with boulders. - [Residence, Belvedere Lagoon](https://www.houzz.com/hznb/projects/residence-belvedere-lagoon-pj-vj~2137810) - Location: Tiburon, CA - Photos: 6 - [My Work](https://www.houzz.com/hznb/projects/my-work-pj-vj~715497) - Location: Kentfield, CA - Photos: 5 [See all 18 projects](https://www.houzz.com/professionals/landscape-architects-and-landscape-designers/simmonds-and-associates-inc-pfvwus-pf~2080604605) --- *Source: Houzz professional profile.
