He was professional, knowledgeable and very easy to work with. He listened carefully to our needs and wishes, and came up with innovative architectural solutions on a challenging site. We just moved to a new house in a different city, and turned to Kyle for our remodeling of the master bathroom and to create a better connection from the family room to the rear yard. We are very pleased with his design and communication skills, and would highly recommend Thayer Architecture for any project. **★★★★★ — Lionel Achuck, June 2016** > Over the past ten years I've hired Kyle to design multiple custom homes in Tiburon, always with terrific results. Kyle stands out as a talented designer who listens to the needs of the client, solves design problems in a creative way and is a pleasure to work with. I will continue to recommend Thayer Architecture to my friends and associates. **★★★★★ — g2ness, May 2016** > I am so pleased to have worked with Kyle to help us realize our vision for our kitchen, dining and family room! He is an imminently creative, experienced, and professional architect who gave us total confidence throughout the project. In addition to proposing details that perfectly enhanced the modern, open style of our Eichler-inspired home, he expertly guided the project through the permitting process so that we received our building permit sooner than we thought. A pleasure to work with! **★★★★★ — Mariner Homes Inc, May 2016** > Over the last 20+ years Kyle has been the only design professional I use for the dozens of properties I've developed in Marin County - everything from high-end custom-built new homes in Tiburon and Mill Valley to value added enhancements to commercial buildings. Kyle is a talented and versatile designer who brings enthusiasm and energy to every project. Kyle is not stuck on a "style” but instead, focuses on good design appropriate for the project - a rare and valuable skill. I never hesitate to recommend him to my friends or business associates. ## Selected projects - [Round Hill Road Residence \#4: A New Custom Home in Tiburon, CA](https://www.houzz.com/hznb/projects/round-hill-road-residence-4-a-new-custom-home-in-tiburon-ca-pj-vj~2069826) - Location: Not specified - Photos: 25 - Description: The scope of work for this new custom home included Preliminary Design, Design Review submittal and approval, Architectural Design, Site Planning and Building Permit submittal and approval.
