The Sienna Company, Inc., is an architectural, design/build company with over four decades of experience in the central coastal region of California. We have designed and/or built of scores of single family residences for private clients and for speculation. We not only listen to the needs and wants of our private clients, but also gently educate them to options and trends for which they may be unaware - that is why you will see a wide variety of architectural styles in our portfolio. In addition to design excellence, we know the proper protocols to reduce time in the oftentimes confusing permitting process. Our objective is to provide the highest quality design and construction within our client's budget and schedule. Our success has been built by combining professional and creative abilities with attentive, personable service.
