We pride ourselves on our outstanding service, attention to detail, and a creative approach committed to the needs of the client. SDG is well versed in the full complement of architectural styles, so whether you are looking for classic, modern, or something in between, we have the knowledge and skill to respond with innovative solutions. SDG Architecture has become especially skilled at maneuvering through the often unpredictable maze of zoning ordinances and design review boards that exist in many of the areas we work in. Projects move along at a steady pace, since the meticulously prepared documents are often approved on the first go-around. Steve continues to serve as a driving force behind every project, and feels one of the most important jobs of the architect is to keep the team – the designers, client, and builder – moving in the same direction so that the finished home will have a cohesive look. Size is not a prerequisite for creativity, nor is budget or style. Rather clients who are up for fun, refreshing, quality architecture are likely to attract the SDG team’s attention.

H. Fry Const. Co., March 2017** > SDG Architects designed a fine home for our client on a challenging lot and managed to make it appear to be simple. The attention to detail, particularly with the stone interiors and exteriors, created a cohesive design. We are always happy to recommend Steve Simpson, AIA, and his team, to create the perfect home. **★★★★★ — HTS Design - Jen Evans, April 2014** > Steve's team did exceptional work designing our family's home. They are thoughtful and collaborative, and we are very happy with the finished product. We especially appreciate Steve's sense of scale and ability to maximize natural light. Kudos to Ami as well for her partnership throughout our project. **★★★★★ — Sullivan Design Studio, Aug. 2013** > Steve Simpson is not only a creative architect but is a fantastic listener. He understands how clients live and function in their homes and as an end result designs homes his clients are thrilled to live in! Steve's homes are both aesthetically beautiful and extremely functional for each individual client's lifestyle. Contractors who work on his projects are also a big fan of Steve's work. We have worked with Steve Simpson and his staff on various projects and will continue to recommend him to our clients. **★★★★★ — Tara Moeller, July 2013** > Steve and his team are top notch professionals. From nuts to bolts, they answer every question (at all times of the night) and as a first time home builder, that was so important to us. We felt so comfortable with Steve's designs and his interaction with the contractors that it was a non-stressful and exciting process. I would recommend him and his firm to anyone that wants to deal with a talented, professional, and extremely diligent group. **★★★★★ — Jane Antonacci Interior Design, March 2013** > I have worked with Simpson Design Group on two different projects where my firm was brought in for the interior design work. Led by Steve Simpson, Steve and his group have a great sense of proportion, style and detailing. I really appreciate his attention to all of the details, which is sometimes missing with other architects I have worked with. Steve always has good ideas on how to solve complicated transitions. As a professional myself, I can always count on Steve to be a good collaborator with me, to solicit and respect opinions of the other professionals on the team and to be a good facilitator on the team. His classical aesthetic, sense of scale and proportion, and ability to work very quickly is all appreciated by the clients. You really can't go wrong with hiring or collaborating with SDG. **★★★★★ — Allwood Construction Inc, March 2012** > Choosing to work with SDG is one of the best decisions a homeowner can make. Every single set of plans we have ever received has been high quality, free of errors, and well designed. Most importantly, each time a client brings us plans drawn by SDG they always express what a pleasure it was working with them. Keep up the great work! ## Selected projects - [Magnolia II](https://www.houzz.com/hznb/projects/magnolia-ii-pj-vj~2828631) - Location: Not specified - Photos: 24 - [Webster](https://www.houzz.com/hznb/projects/webster-pj-vj~2472871) - Location: Palo Alto, CA - Photos: 13 - [Rebecca Lane](https://www.houzz.com/hznb/projects/rebecca-lane-pj-vj~2031179) - Location: Not specified - Photos: 26 - [Triple L](https://www.houzz.com/hznb/projects/triple-l-pj-vj~1277829) - Location: Not specified - Photos: 25 - [Shades of White](https://www.houzz.com/hznb/projects/shades-of-white-pj-vj~452199) - Location: Not specified - Photos: 15 - Description: A modern farmhouse in shades of white. - [Park Lane](https://www.houzz.com/hznb/projects/park-lane-pj-vj~2085228) - Location: Not specified - Photos: 20 - [Two Oaks](https://www.houzz.com/hznb/projects/two-oaks-pj-vj~2137120) - Location: Not specified - Photos: 21 - [Amherst](https://www.houzz.com/hznb/projects/amherst-pj-vj~143936) - Location: Los Altos Hills, CA - Photos: 12 - [Cornell](https://www.houzz.com/hznb/projects/cornell-pj-vj~918821) - Location: Not specified - Photos: 6 - [Barron Park](https://www.houzz.com/hznb/projects/barron-park-pj-vj~1280869) - Location: Not specified - Photos: 20 - [El Cerrito II](https://www.houzz.com/hznb/projects/el-cerrito-ii-pj-vj~613268) - Location: Not specified - Photos: 7 - [Fox Hollow](https://www.houzz.com/hznb/projects/fox-hollow-pj-vj~59195) - Location: Woodside, CA - Photos: 17 - Description: This modern farmhouse is nestled in the dense redwoods on a three acre wooded lot set alongside a creek and riding tail.
